Message of Engr. Armando R. Diaz

I would like to call this Annual Convention a “homecoming”. A homecoming, which makes family members come together. This occasion brings nostalgia, once more waking up old memories of yesteryears that bounded us together to become not just friends or colleagues but a family. A family that shares pleasures, dreams, experiences and knowledge for a fruitful advocacy aimed for the advancement of technology and the development of eco-consciousness in a progressive nation seeking further advancement in the industrial world..Ladies and gentlemen of Institute of Integrated Electrical Engineers … my family…Magandang umaga po sa inyong lahat.

Welcome to IIEE’s 36th Annual National Convention. The Institute of Integrated Electrical Engineers conferences like this one, is one of the most enjoyable and rewarding privileges of IIEE membership. Occasions like this in IIEE, opens doors to countless opportunities. Here, you meet old friends and make new ones. Thus, you expand your network of friends and discover new sources of information that would update you to new knowledge necessary in modern industry.

Occasions like this also makes you feel proud of your profession, inspiring you to learn some more, encourage you to share your skills, and motivates you to participate in nation building, which our country direly need in these fast changing times of industrial, and economic development.

To the romantic, especially those active members whose days with IIEE had been illustrious, similar conferences bring back old memories…flipping calendar pages backwards..

Pilit na ibinabalik ang ala-ala ng lumipas, sinasariwa ang ligaya sa kabila ng hirap at dusa upang maging matibay at matatag ang institusyong ito, na ngayo’y isa nang simbolo ng ating piniling propesyon, mandi’y kanlungan ito ng karunungan,karanasan,at matalik na pagkakaibigan.

This conference particularly, is one of the golden pages of my book life. It is the most important chapter that describe my love affair with my profession.

Thirteen years ago in 1998 , I was awarded the honor of being the most outstanding professional in the field of industry, Five years ago in 2006 , I was inducted as one of the Governor at Large and as well as conferred an IIEE Fellow.

All these happened here at PICC. Now, 2011, the year of metal rabbit ,which gave us a lot of things to look forward to, I am delivering my final message as your National President here at PICC… the very place where it all started . Needless to say , this one is indeed memorable to me.

Today, I am proud of IIEE’s numerous achievements..

I wish that everyone, like us in IIEE Board are equally or better inspired in what we are doing today and what we have done during the year. If we as a citizen have an obligation to fulfill for our country, we as professionals have obligations to our profession, as members of IIEE, we are obliged to serve society. My friends, I wish to see the day , that someone from these attendees be a National President of our prestigious IIEE. To have a hand in running the institute is an admirable honor, which is more than just a star on one’s shoulder. It is a pride and great privilege more than just any other.

National Presidents before me have laid-out their agenda to make IIEE a better IIEE. I am proud of their achievements, which we enjoy today.

My vision is to make IIEE a gainfully distinct pool of citizen-friendly and environment conscious electrical engineers, integrated to the development of a nation. My vision is focused on new avenues where IIEE could actively venture. Nation building through modern technology and industry will be our quest. We drew our 4-Circuit Program to be our working guide .We called it Circuit Program to jive with words common in the practice of our profession. The 4-circuit program aims to give more muscle to the institute; advocate membership strength and professional competence; a new functional policies and public relations programs; and emphasize new methods in reducing the industries carbon print in the environment.

We began our public relations program with an Electrical Safety Enforcement and Awareness or ESEA. Last February 20, 2011, we signed a memorandum of agreement with ICASEA for a three-year electrical safety program which was designed primarily “ to enhance the enforcement of Philippine Electrical Code, build capacity for the improvement of local electrical inspector’s skills and increase public awareness toward electrical safety.

To give prominence to the campaign we requested AGHAM as sponsoring partner to make representation to the Phil Congress thru Cong. Angelo Palmones to declare the month of May this year and thereafter as ELECTRICAL SAFETY MONTH.

Ladies and Gentlemen with this Executive Proclamation..193...This will put us all in the forefront of a scheme to provide electrical safety in the household, streets, offices, and factories in every barangays, towns, and cities of the country… There is no thrill quite like doing something you did not know you could.

Nakita natin ang katotohanan sa salawikaing “ hindi tayo makakatuklas ng bagong dagat kung wala tayong lakas ng loob na mawala sa ating pananaw ang pampang.”

Once more we have proven that in life, nothing is impossible…More could be done, if we shall stay together and diligently with passion, for our profession, for ourselves, for our family, for the society, work….for the country, Let us do all these together.

Thank you and Merry Christmas to all!

IIEE Leads Disaster-Management Advocacy

The Institute of Integrated Electrical Engineers (IIEE), Inc. is not only an institution serving its immediate constituents of professionals but deserves a whole lot of credit for intending to go the extra mile in serving the general community through its own initiative of advocating a “Disaster Management” campaign on top of other priorities in pursuit of public safety and security.

Over the past several years, responses to major disasters have become apparent from local relief organizations to the international community in aid of the government’s capability to alleviate the suffering of victims of calamity. However, due to constraints on disaster risk reduction procedures, the present system manages to get to the bottom of these incidents barely repairing the damage. Be that as it may, mere food and material provisions only temporarily eliminates the inconvenience and nothing more.

The rapid growth of population and increased settlement in hazardous locations just escalates the frequency and severity of natural disasters. Studies made by the University of Delaware’s Disaster Research Center manifests that disasters are the results of human failure to introduce appropriate disaster management measures for the reason that human actions before the strike of the hazard can prevent it developing into a disaster. (“At Risk-Natural hazards, people’s vulnerability and disasters” by B. Wisner, et. al.).

Just recently, the organization channeled its voluntary involvement in mitigating disaster-inflicted calamities costing lives and properties which has become a usual sight globally. The very recent in the country being the flooding caused by tropical typhoon “Sendong” leaving 1,010 casualties with hundreds still missing in Mindanao (Inquirer Headline, 19Dec2011) by Institutionalizing a “Disaster Response Committee” as ardent move.

It may be that IIEE does not mobilize response units directly under a commanding officer but the skills of its members are well-suited for the role of preventing hazards from coming to

fruition.

In a joint meeting between the Council of Former Presidents (CFP) and IIEE Board of Governors (IIEE-BOG) last November 25, 2011 at the Institute H e a d q u a r t e r s , it invited r e p r e s e n t a t i v e s

from two of the country’s powerful forces often tapped during disaster control call-ups; the Philippine Navy Reserve Forces (PNRV) and the Armed Forces of the Philippines (AFP). Representing the authorities were Lieutenant Commander Ferdinand Juan of the Philippine Navy Reserve Force who is also the Chief-of-staff of the Naval Affiliated Reserve Force, and Lieutenant Colonel Dennis Bumanlag of the AFP, both belonging to the Scout Ranger Regiment.

Lt. Commander Juan entitled his presentation “Power to save more lives” which he tailored specifically to suit the Institute’s reflection. There was a clear manifestation that the Institute could deliver its expertise having an absolute reserve of 36,000 active members of professionals, 77 local chapters and 8 foreign chapters possessing the engineering know-how and capability to design a habitat that is less vulnerable to risks.

This assemblage provided just the right amount of stimulus to drive more responsible citizens towards risk reduction strategies and pre-planning activities where preparedness would be the ultimate objective. This call to action can be described as a pooling of all resources available for a good cause.

Motor Performance DataRESEARCH BY THE ElECTRIC POWER RESEARCH INSTITuTE, INC. (EPRI)

6.1 Motor Performance History

Not every motor in a plant or other facility will be monitored or have data collected for tracking or trending. Once the importance of a motor has been established based on plant or system design, then a program for condition monitoring should be established for that motor.

When faced with a motor problem, it would be valuable to have operational history to review. However, many motors are either not instrumented or not deemed important enough to have this data collected. Many times when called in to evaluate a motor’s condition, the person performing the evaluation is making a fairly strong assumption regarding the past handling and performance of a motor if there is little or no condition monitoring data available. Also if themotor was not quarantined until proper investigation, valuable data could be lost.

Surrounding the motor is the system that consists of power supply, driven equipment through a mounting and coupling set-up, and the environment

affect a motor’s condition. Failure toconsider external influences may lead to an incorrect diagnosis of a motor failure.Although a complete system analysis is not the focus of this report, it is important to recognize that the motor is only one component of a system. Many factors will affect the system that includes the motor and then contribute to motor failure. The converse of the previous sentence istrue also. Figure 6-1 illustrates the symbiotic relationship between a motor and the system that it operates in.

Table 6-1 list the typical stresses that will affect a motor and the most likely component that will be affected:

6.2 Capturing Data

Electric motors are fairly rugged pieces of equipment and should provide years of trouble free service. There is a minimum amount of data that can be collected for motors that are deemed important to system or plant operations.

After installation, motors are typically checked out to ensure proper operation. Items such as proper supply voltage, running current, motor speed, bearing and winding temperature (if possible) were recorded in some form at initial installation. If this basic information was not collected, it would be prudent to collect that information for important motors.

The importance of a motor does not totally depend on it’s rating (such as horsepower, voltage) but on it's application. There may be small motors in terms of horsepower rating but because of application, it may limit the operation of a system or plant.

Technical Feature

Without baseline data, a condition that has been reported as a problem may have existed since the installation of a particular motor. If the motor has been operating for many years, it appears that the conditions may be acceptable for that motor in that particular application. If it is notbroken, why fix it?

The responsible motor person should have the tools available to capture data for important motors in order to make determinations on motor condition and to evaluate if the data represents a condition that will be detrimental to the continued operation of a motor.

One of the most important tools available is external inspection. The general condition of a motor as well as any abnormal condition such as lubricant leakage, plugged air passages, abnormal sounds and smells can be noted. Motors that are instrumented make the task of data collection and condition monitoring somewhat easier and more consistent.

Trouble Shooting SummaryThe analysis of motor problems must include the system in which a motor is located. The three major elements include:

• The Power Supply: Distribution System and Motor Controls• The Motor: Stator, Rotor, Bearings and Accessories• The Load: Driven Equipment and

The Process Upon inspection, the motor may be found damaged but the root cause of failure may be either the power supply or the load. Hence, these three elements must be treated as a single system to accurately determine a root cause. Failure to do so can result in affecting a motor repair and only have it fail again because the source of the problem has not been removed or corrected.

Throughout an investigation, one must continue to ask the question: “Is this damage the result ofexternal or internal forces acting upon the motor?”

Normally, a good starting point is to assure that the correct voltage is being delivered to the motor terminals. This can normally be done at the motor control center without disconnecting, the motor leads in the terminal box.

Next a review of the driven equipment and the process can be helpful. There are occasions when it may be necessary to disengage the motor form the load to assure that the drive train is free to rotate.

Most large motors have a number of protective devices that need to be considered when trying to determine why the motor alarmed or tripped off the line. These devices may include some of he following:• Over current devices• Current differential protection• Winding RTD’s or equivalent• Bearing RTD’s or equivalent• Surge Protection• Vibration Sensors• Pressure differential switch on filters• Zero speed protection

Modelling and Simulation of Active Power Filters for Harmonic Compensation, voltage Sags and Swells Mitigation and

Power Factor CorrectionMichael C. Pacis, Jesus M. Martinez Jr., and Jaypee v. Tecson

Abstract— The two major problems in the electrical industry today are sagging and swelling of line voltage and harmonic currents. Voltage sagging and swelling may result to equipment malfunction and shut down. Harmonics also affect the electrical equipment to fail and deteriorate the waveform of the current. To mitigate the voltage sags and swells, uninterrupted power supply was used. But uninterrupted power supply is an example of non-linear load which creates harmonics in the power system. Active power filters were used to eliminate the harmonics in the system. This study aims to create three models of active power filters that compensate the harmonics, mitigate the voltage sags and swells, and also correct the power factor. The models were simulated to know which of the three active power filter models gives the best performance. The simulation tools that were used in this study were MATLAB/Simulink and TINA PRO. Based on the results, the active power filter models compensate the harmonics, mitigate the voltage sags and swells, and correct the power factor of the system. Evaluating the models, the active power filter Model-A gave the best performance by reducing the total harmonic distortion of the system.

index Terms— active power filter, harmonics, voltage sags and swells, power factor correction

I.INTRODuCTIONAs time passes by, the world of technology evolves to a more advance and becomes widely developed. Different devices were formed such as high-end personal computers, laser printers and other electronic equipment. These devices are very sensitive to voltage sags and swells. Bingham defined voltage sags in his study as “the decrease in voltage lower than a user defined low limit” while voltage swells was defined as “voltage that surpass the user defined high limit” [1]. The more advanced and sophisticated the equipment is, the more it is sensitive to sagging and swelling of voltages. Voltage sags and swells are the most occurring power system problems today that can cause electrical equipment to fail or

shut down [3]. To mitigate the voltage sags and swells, uninterrupted power supply (UPS) were used. Uninterrupted power supply is an example of non-linear loads. Other examples of non-linear loads are laptop, stereo, fax machines, television set and telephone system [5],[6]. Non-linear loads create harmonic current and increase the deterioration of the power systems voltage and current waveforms. These loads causes the sine wave of the current o deform [2]. Harmonics in the power system can be measured through the measurement of total harmonic distortion (THD) [4]. Due to the current wide use of non-linear

loads, harmonics became a major issue in the electrical industry. Active power filters were used to compensate the harmonics in the power system. This research paper focused on modelling and simulating active power filters that can compensate both harmonics and voltage sags & swells which both cause severe problems in the electrical power system.A study was conducted by M. Tarafdar Haque [7] regarding simulation of active power filter as an efficient and economical way of eliminating harmonics in the power system. The controls of the active filter were based on the instantaneous active and reactive power theory. MATLAB was used as a simulation tool for the active power filter. The study turned out that the active filter produced better results for correction of power factor and elimination of harmonics compared to the usual method which is passive filter for conditioning current harmonics and capacitors for correcting the power factor. This study offers to solve other major electrical power system problem. Not only that the active power filter models can compensate harmonic and correct power factor but rather it can also mitigate voltage sags and swells. This study will also widen up the features of an active power filter and will serve as a new solution for the power system problems. The researcher created three different models of active power filter. At the end of this study, the researcher will choose which of the three active power

filter models gave the best performance. From the models generated in this study, interested researchers could innovate and enhance it by creating a complete equivalent circuit or a prototype of the active power filter models. The purpose of this study is to create three different models of active power filters and evaluate their performance on different harmonic conditions. Simulating tools such as MATLAB/Simulink and TINA PRO can be used to evaluate the performance of the active power filter models. After simulating each active filter model one by one, each model must compensate the harmonics, correct the power factor and mitigate the voltage sags and swells. At the end of this study, the researcher will evaluate and compare the results of the simulation of the models and choose the best active power filter model among the three models. Another purpose of this research paper is to construct an equivalent circuit for the voltage sags and swells submodel.

Furthermore, this study will help the electrical power system from the generation side up to the distribution side because this will serve as a solution for harmonics, voltage sags and swells, and power factor correction in the power system. There will be reduction of voltage drop in long transmission lines. There will also be reduction of losses, therefore, wasted energy will be minimized [6]. There will be extra

apparent power available for additional loads that may be inserted in the power system. Commercial and industrial customers will save more money because their electricity bills will be reduced. There will be continuous production and service because electrical disturbance will be mitigated. All the end users will benefit because the equipment will be protected at the same time its life will be extended. The simulation tools to be used in this study are MATLAB/Simulink and TINA PRO. This study focuses mainly on the creating three different active power filter models and evaluating each model’s performance in seven different harmonic cases. The harmonic currents to be compensated by the Simulink filter model will range from second harmonic current to seventh harmonic current. For the Simulink model for voltage sags and swells, there will be two cases for voltage sags mitigation and two cases for voltage swells mitigation. For the TINA pro simulation, there will be ten cases for power factor correction. Since the usual load in the industry is an inductive load, the simulation for power factor correction in tina pro will cover lagging power factor. The simulation for Simulink power factor correction model will cover both lagging and leading power factor. However, this study is only limited to single phase circuits and single phase active power filter models.

II. METHODOLOGyThe methodology of the study was based on Figure 1. Three active power filter models were simulated to eliminate the problems. Each active power filter model was composed of submodels for voltage sags and swells mitigation, harmonic compensation and power factor correction. The researcher decided to simulate separately the submodel for voltage sags and swells since all three active power filters have the same voltage sags and swells mitigation submodel. The researcher used two different softwares to simulate hand in hand the models. MATLAB/Simulink was used first to simulate the voltage sags and swells submodel and harmonic compensating submodel combined with power factor correction submodel. TINA

PRO was used to simulate the circuit for the power factor correction.

A. MATlAB Simulink model for voltage sags and swells mitigationThe first submodel generated was the voltage sags and swells mitigation. The block diagram of the voltage sags and swells mitigation submodel was composed of the rectifier, switch mode DC to DC regulator and inverter [4]. Figure 2 shows the block diagram of voltage sags and swells mitigation submodel while Figure 2 shows the Simulink model for the voltage sags and swells mitigation. The model of the voltage sags and swells shown in Figure 3 was the equivalent of the block diagram in Figure 2. The block diagram was used to serve as a guide to build the voltage sags and swells mitigation submodel.

Iv. SIMuLATION RESuLTS uSING TINA PRO By looking at Table 7, the power factor from 0.50 was corrected to unity. The capacitance for case one was 192uF to correct the power factor of 0.5 to 1. For trial one, capacitor switches were opened to see the old power factor. For trial two, the capacitor switches were closed to give a correct capacitance that will correct the old power factor to unity. The computations matched the results of the TINA PRO simulation. TINA PRO simulation shows the implementation of the Simulink model for power factor correction.

v. CONCLuSIONInitially, the active power filter mitigated the voltage sags and swells of the circuit then it compensated the harmonic currents in the line current. The sagged or swelled voltage was rectified to convert AC voltage to DC by using the bridge type rectifier and capacitor. The DC output of the rectifier was controlled by the switch mode DC to DC regulator. The feedback comprising of a multiplier, a constant block that acts as a reference voltage, a PID controller and a low pass filter circuit was the error checker of the DC to DC regulator to maintain a certain DC value. For the practical application of this, voltage divider was used to regulate the voltage which was showed on the equivalent circuit of the voltage sags and swells mitigation model.

The first low pass filter which was interpreted as a capacitor and acts as an AC filter eliminates the fundamental frequency and harmonics while the second low pass filter that acts as a DC filter eliminates the harmonics and the switching frequency. The output of the regulator was multiplied to a square wave generator in order to change DC back to AC. The square wave of the circuit can be an internal clock or a 555 square wave oscillator. Since the model for voltage sags and swells mitigation is very effective, the output of this circuit will always be an RMS voltage of 220V because of the DC to DC regulator. Regulating the voltage was done in DC to utilize the available DC – DC switching technique which is popular today. The active power filter compensates all harmonic currents and reduces the total harmonic distortion of the system. It also smoothens the distorted waveform of the load current into a pure sinusoid. Among the three active power filter models, active power filter Model-A gave the best performance compared to the other two models. Model-A reduced the percentage of total harmonic distortion of the systems greater than the two remaining models.

Since all the voltage and current whether distorted or not became in phase with each other in all cases, the power factor of the system were all corrected to near unity. Tina pro simulation was the implementation of the MATLAB/Simulink model for the power factor correction. The active power filter will switch on the correct capacitance to correct the power factor to unity once the active power filter detects the load voltage and load current. Therefore the active power filter models were effective in correcting the power factor of the system to near unity.

Power Quality Case Study:

Harmonic Problem

Measuring Tools: Power Quality Analyzer Operator: Access Frontier PTE lTDFeatures used: Current, Harmonic Spectrum, THD

Problem Description

This case history comes from an electrical contractor. Several of this contractor’s clients operate large commercial buildings. One of these clients asked for help with a large transformer that had suddenly started vibrating and making a loud buzzing sound. The client was concerned that the transformer was ready to fail and he would be faced with an expensive replacement. The contractor dispatched an engineer at once.

When the engineer arrived at the plant, he took out his notebook and his Fluke 43B. He then made the following notes and one line diagram:

Transformer size: 1500 kVA

Transformer configuration: Delta/wye, 480V 3-phase secondary

Secondary Load: Motors, lighting, and office machines for a large office building

Note: The client says the transformer is lightly loaded because many of the tenants have recently moved to a new location.

Measurement Data

The engineer recorded the following data using the Fluke 43B:

Secondary voltage total harmonic distortion: 2.7%Secondary voltage balance: within 1%

Secondary current: 57A rmsSecondary current spectrum:Fundamental 55 Amps 2nd harmonic 1.6 Amps 3rd harmonic 2.5 Amps 4th harmonic 0.7 Amps 5th harmonic 2.4 Amps 6th harmonic 0.4 Amps 7th harmonic 4.0 Amps

Theory and Analysis

The voltage measurements do not show anything abnormal. The voltage total harmonic distortion is well within the maximum allowable value of 5%. Voltage balance between phases also looks good. The secondary current of 57A indicates the client was correct in stating the transformer was lightly loaded. No overheating was noted.

When a transformer is in trouble, this contractor’s engineers always use a Fluke 43B to measure the harmonic spectrum of the secondary current. The spectrum acts like a fingerprint, indicating the types of loads present. In the above case, the presence of the 3rd harmonic shows that part of the load consists of single-phase devices (e.g., fluorescent lighting ballasts) connected phase to neutral. In the above data, the amount of the 3rd harmonic is relatively low and appears to be normal.

The 5th and 7th harmonics indicate that part of the load is a large 3-phase device with semiconductor rectifiers

in the input circuit. The most common example would be an adjustable speed motor drive operating a fan or pump. When a 3-phase motor drive is operating normally, the input current waveforms are symmetrical about zero. That is, the positive going portion of the waveform looks like the mirror image of the negative portion. When all semiconductors are operating normally, the input currents have no dc offset and only odd harmonics are present.

The engineer noted that the spectrum had even harmonics (2nd, 4th, and 6th). These abnormal harmonics indicate the presence of dc current in the transformer secondary winding. Compare the example spectrums in Fig. 2 and Fig. 3. Unfortunately, dc current tends to saturate the transformer core at the peak of one half of the ac waveform. When the core goes in and out of saturation, it will vibrate and make a loud buzzing noise.

The engineer suspected that the plant load contained a large motor drive and that one of the input semiconductors had failed open. If one semiconductor is open, the circuit on that phase becomes a half-wave rectifier—it produces dc current. The trick here is that the motor drive will continue to operate at low speed because the other two phases are operating normally.

Solution

The engineer asked if any large motor drives were operating. The plant manager confirmed that one large drive was operating a ventilation fan. The engineer instructed the plant manager to have the drive shut off. When the drive was shut off, the transformer immediately stopped vibrating.

Equipment PQ Performance StandardsDean Arnold S. Sempio and Rolan S. Mercado

MERALCO

Various “ride-through capability standards” were made in order to aid manufacturers and the electric utilities in establishing a common viewpoint of how electrical equipment would behave on certain voltage events. Manufacturers design equipment based on the “compromised” levels between the equipment capability and grid performance of the utility. Developed in the 1970s (originally, the CBEMA, Computer and Business Equipment Manufacturers Association) and revised in 2000, the ITIC (Information Technology Industry Council) curve is now one of the most common tools available to engineers; using the ITIC curve can help point map the sensitivity of electronic equipment or help improve the performance of a power distribution system. Here is the ITIC curve:

The ITIC curve shows two lines representing the upper and lower limits. In the upper limit, voltages up to 500% of the nominal may not cause damage to IT equipment IF the duration is below the curve’s specified time limit. This category includes voltage transients as well as voltage swells.

The SEMI F47 standard is another voltage sag susceptibility curve which is intended specifically to semiconductor manufacturing equipment, which include etch equipment, thermal equipment and ion implant equipment.

SEMI F47 “Specification for Semiconductor Processing Equipment Voltage Sag Immunity” defines the voltage operating limit that semiconductor processing equipment can operate through without stopping its operation. Voltage values below the SEMI F47 curve may cause the semiconductor equipment to malfunction or stop operating altogether due to lack of the required operating energy.

These tools are incorporated into several power monitoring equipment output as aid to the engineer’s study on voltage tolerance of equipment as well as providing a list of disturbances in the power grid being monitored. The usefulness of these tools is illustrated in the case study below:

Semiconductor Processing Equipment

Problem

A semiconductor manufacturing company has requested a power quality monitoring due to “voltage fluctuations” (i.e. voltage sags) affecting the operation of their equipment, particularly their tunnel furnace. A Power Quality monitoring device was installed at the panel serving the customer equipment.

PQ Monitoring Results

The data from the monitoring showed that the voltage regulation, voltage unbalance and voltage harmonic distortion to be within industry parameters. However, the data from the monitoring also captured several voltage sags events. The characteristics of the voltage sags (voltage magnitude and duration) were plotted in the SEMI F47 curve:

In the days before computers, most electrical loads consume power linearly – that is, the current drawn traces the voltage waveform. Today, the widespread use of electronics in the industries has created a demand for better power quality as electronic equipment are not as tolerant of voltage waveforms and events as the old loads. Ironically, these electronic equipment are non-linear loads that draws non-sinusoidal current and causes voltage waveforms to be distorted.

Technical Feature

According to the company, the tunnel furnace has stopped operating more than 7 times during the monitoring period; much more than the three events that violate the SEMI F47 curve. This suggests that the equipment is much more sensitive to voltage sags as it should be.

SolutionA UPS unit was recommended to increase the voltage sag tolerance by providing power to the equipment controls during a voltage sag event. The customer was surprised when the equipment vendor pointed out that there is a UPS option for their equipment, the customer need only to specify for the UPS option to be installed.

variable Speed Controls

Problem

A customer in the manufacturing business has complained that frequent voltage sags has reduced the operating time of a vital equipment being controlled by a variable speed drive.

Power Quality monitoring

A Power Quality Analyzer was installed at the panel serving the customer equipment. The data from the monitoring shows that the voltage regulation,

voltage unbalance and voltage harmonics were all within industry limits and should pose no problem to the VSD operation. However, the following voltage sags were captured by the equipment:

Most of the sags captured were verified by the customer as enough to cause the stopping of the VSD operation.

Solution

The data showed that most of the voltage sags were “shallow”; the voltage values went down to only 88% from their nominal values. A cost effective solution was recommended as the PQ engineer observed that the equipment is being sole load of a secondary transformer. It was recommended that the transformer’s

tap setting be changed to increase the secondary voltage. The increased voltage will still be within the operating limits of the VSD but will increase the stiffness of the electrical system against voltage sags.

Conclusion

The usefulness of equipment operating standards is not limited to utilities and equipment manufacturers. Ultimately, the equipment users will also benefit from the increased reliability and use of equipment that passes these operating standards.
