General

Awareness of the necessi ty of power quality is increasing, andpower factor correction (PFC) willbe implemented on a growingscale in future. Enhancing power quality – improvement of power factor – saves costs and is a fast return on investment.In power distribution, in low- andmedium-voltage networks, PFCfocuses on the power flow (cos ϕ)and the optimization of voltagestability by generating reactive

power – to improve voltagequality and reliability at distribution level.

How reactive power isgenerated

Every electric load that works withmagnetic fields (motors, chokes,transformers, inductive heating,arc-welding generators) producesa varying degree of electrical lag,what is called inductance. This lagof inductive loads maintains thecurrent sense (eg positive) for atime even though the negative- going voltage tries to reverse it.This phase shift between current and voltage is maintained, current

and voltage having opposite signs.During this time, negative power or energy is produced and fedback into the network. When current and voltage have the samesign again, the same amount of energy is again needed to buildup the magnetic fields in inductive

loads. This magnetic reversalenergy is called reactive power.In alternating voltage networks(50/60 Hz) such a process repeats50 or 60 times a second. So anobvious solution is to briefly storethe magnetic reversal energy incapacitors and relieve the network (supply line) of this reactiveenergy.For this reason, automatic reactivepower compensation systems(detuned/conventional) are installedfor larger loads like factory plants.Such systems consist of a group of capacitor units that can be cut inand cut out and which are drivenand switched by a power factor controller as determined by acurrent transformer.

Power factor Low power factor (cos ϕ)

Low cos ϕ results ina higher energy consumption

and costs,a less power distributed via the

network,a power loss in the network,a higher transformer losses,a

increased voltage drop inpower distribution networks.

Power factor improvement

Power factor improvement can beachieved by a compensation of reactive power

with capacitors,a active compensation – using

semiconductors,a overexcited synchronous

machine (motor/generator).

Types of PFC(detuned or conventional)

a individual or fixed compensation (each reactive power producer is individually compensated),

a group compensation (reactivepower producers connected asa group and compensated as a

whole),a central or automatic compensa-

tion (by a PFC system at acentral point),

a mixed compensation.

Fundamentals ofPower Factor Correction

What is power factor correction?

The rational use of electricalenergy calls for economical gener- ation, transmission and distribution with little loss. That meansrestricting all factors in electricalnetworks that cause losses. One of these factors is lagging reactive

power. Consumers in industrialand public electrical networks areprimarily of an ohmic-inductivenature.The purpose of systems for power factor correction in networks is tocompensate the generated lagging reactive power by leadingreactive power at defined nodes.In this way impermissibly highvoltage drops and additionalohmic losses are also avoided.The necessary leading power is

produced by capacitors parallel to

the supply network, as close aspossible to the inductive con- sumer. Static capacitive compensation devices reduce the laggingreactive power component trans- mitted over the network. If network conditions alter, the requiredleading reactive power can bematched in steps by adding andtaking out single power capacitors(regulated PFC) to compensate thelagging reactive power.

Key componentsPFC controller

Modern PFC controllers are microprocessorized. The microprocessor analyzes the signal from a current transformer and produces switching commands to control the contactors that add or remove capacitor stages. Intelligent control by

microprocessorized PFC controllersensures an even utilization of capacitor steps, minimized number of switching operations and optimized life cycle.

Fuse

An HRC fuse or MCCB acts as asafety device for shortcircuit protection.

Capacitor contactor

Contactors are electromechanicalswitching elements used to switchcapacitors or reactors and capaci-

tors in standard or detuned PFCsystems. The switching operationcan be performed by mechanicalcontacts or an electronic switch(semiconductor). The latter solution is preferable if fast switchingis required for a sensitive load for example.

Reactor(compensation and filtering)

Power distribution networks areincreasingly subjected to harmonicpollution from modern power electronic devices, socalled nonlinear loads, eg drives, uninterruptible power supplies, electronicballasts. Harmonics are dangerous

for capacitors connected in thePFC circuit, especially if the capacitors operate at resonant frequency.The series connection of reactor and capacitor to detune the seriesresonant frequency (the capacitor's resonant frequency) helpsto prevent capacitor damage.Critical frequencies are the 5th and7th harmonics (250 and 350 Hz).Detuned capacitor banks alsodecrease the harmonic distortionlevel and clean the network.

Capacitor

Power factor correction capacitorsproduce the necessary leadingreactive power to compensatethe lagging reactive power. PFCcapacitors should be capable of withstanding high inrush currentscaused by switching operations(> 100 * IN). If capacitors are

connected in parallel, ie as banks,the inrush current will increase(≥ 150 * IN) because the chargingcurrent comes from the grid aswell as from capacitors parallel tothe switched one.

Benefits of power factor correction

a Amortization in eight to24 months through lower power costs

Power factor correction reduces

the reactive power in a system.Power consumption and thuspower costs drop in proportion.

a Effective installation use

An improved power factor meansthat an electrical installation worksmore economically (higher effective power for the same apparent power).

a Improved voltage quality

a Fewer voltage drops

a Optimum cable dimensioning

Cable cross-section can bereduced with improvement of power factor (less current). Inexisting installations for instance,extra or higher power can betransmitted.

a Smaller transmission losses

The transmission and switchingdevices carry less current, ie only the effective power, meaning that the ohmic losses in the leads arereduced.

Voltage fluctuations (transientovervoltage, up/down voltagefluctuation, flicker)

These are mostly caused by thepower consumption of large loadslike welding machines and arcfurnaces, or by heavy power fluctuations. These random voltagefluctuations are often also referred

to as flicker, because they arenoticeable as visible alterations inlighting installations. They are not

only disturbing to the human eye,they can also disrupt sensitiveproduction processes. On weak networks, flicker can affect largegeographic areas. Dynamic voltage compensation is a possibleremedy.Harmonic distortion is the result of nonlinear loads and can also leadto malfunction of the equipment connected. Apparatus can bedamaged by resonant effects ina network. Active and passivefilters offer protection against thisphenomenon.

Commutation notches are usually produced by power electronicdevices and can be reduced by circuitry measures.

Design of capacitors

a MKK/MKP technology

The broad field of application for capacitors combined with physicaland economic considerationscreates the need for different dielectric technologies.When it comes to low-voltagepower factor correction, MKK/MKP

(metalized plastic film/polypropylene) has demonstrated that it iscurrently the most suitable andmost economic technology. Thethickness of the dielectric differs asa function of voltage rating. Themetalization (with zinc and aluminum as its major constituents)and edge enhancement withextra junctions or cross-profilemetalization play a significant rolein achieving high current handlingand stable capacitance at high

operating temperatures. Heavy edged and special film cutting

technique (optimized combinationof wavy and smooth cuts) produces a maximum effective surfacefor the metal spraying or contact- ing process (winding design). Thisresults in exceptional surge current capability. The pinching effect onthe film edge of the winding – thecause of contact edge problems – is demonstrably eliminated in thisway.

a Self-healing

An electric breakdown is possibleas the result of thermal or electricoverload or at the end of servicelife. This results in a small arc that evaporates the metalization in theregion of the breakdown in amatter of microseconds. The gaspressure caused at this spot by thehigh temperature blows the in the

meantime vaporous metalizationout of the breakdown region.Which means that a non-conduct- ing isolation region free of metalization is formed here.

During and after the breakdownthe capacitor is fully functional. Thereduction in capacitance caused by self-healing is less than 100 pF, ie of an order that can only be verifiedby a precision measuring instru- ment.

a Vacuum impregnation

The active winding elements areheated and then dried for adefined period. Impregnation (egby gas) is performed in a highvacuum. In this way air and moisture are extracted from the inner capacitor, and oxidation of the electrodes as well as partial dischargesare avoided. Afterwards capacitorsare hermetically sealed in cases (egaluminum). The elaborate processensures excellent capacitancestability and long service life.

a Overpressure disconnector

Electrical components do not haveunlimited service life, that appliesto self-healing capacitors too. Aspolypropylene type capacitorsseldom produce a pronouncedshortcircuit, fuses do not offer reliable protection. All capacitors featured in this cata-

log are consequently fitted with adisconnector that responds tooverpressure. If numerous electricbreakdowns occur at the end of

service life or as the result of thermal or electric overload, the for- mation of gas produces a fast risein pressure inside the capacitor case. With cylindrical cases thiscauses a change in lengthbecause of curvature of the lid or stretching of the expansion bead.Expansion beyond a certaindegree will separate the internalwires and disconnect from theline. Then the capacitor receivesno more energy and the development of gas stops.

To ensure full functionality of anoverpressure disconnector, itselastic elements must not behindered, ie– connecting lines must be flexible

leads (cables),– there must be sufficient space

for expansion above the connec- tions (stated for the different models),

– folding beads must not beretained by clamps

Definitions

a Temperature class of capacitorsto standard IEC 831-1

Capacitors are divided into temperature classes. Each class isrepresented by a number followedby a letter, eg –40/D. The number is the lowest ambient temperatureat which a capacitor may operate.

The upper limit temperature isindicated by the letter (see tableabove).

One should always remember that the useful life of a capacitor depends very much on temperature. Proper cooling of a capacitor must ensure that the maximumcase temperature is not exceeded,otherwise service life is degraded.When configuring a circuit, oneshould make sure that capacitorsare not subjected to heat from

adjacent components (reactors,bus bars, etc). Forced cooling ispreferable for compact designs. And it is highly inadvisable toarrange capacitors directly abovereactors.

a Enclosure of capacitors (IPxx)

For different models there aredifferent types of enclosure. Thetype of enclosure is indicated by adesignation consisting of the twoletters IP followed by two digits.

a Maximum admissibleovercurrent

The nominal current (IN) is the

current resulting for nominalvoltage (UN) and frequency (Hz),excluding transients. The maximum admissible overcurrent (Imax)of 1.5 * IN to IEC standard 831 ismaintained by all capacitors inthis catalog. The figures for overcurrent allow for the combinedeffects of harmonics, overvoltageand capacitance tolerance.

a Maximum admissibleovervoltage

Capacitors from EPCOS are suitable for operation on overvoltagesquoted by IEC 831 (see table).

a Useful life

The statistical useful life of power capacitors is governed by thefollowing factors:– duration of overload,– ambient temperature and the

resulting case temperature,– maximum rms current and the

resulting case temperature,

– maximum voltage.The calculated service life of thevarious series is stated for nominaloperating conditions. If components are stressed less than theabove IEC 831 factors, longer useful life can be expected, and acorrespondingly shorter one if nominal parameters are exceeded.

Application notes

a Fuse protection

Power capacitors can be protectedagainst shortcircuits by fuses or magnetic shortcircuit releases.Preferable are slow-blow, low- voltage high-breaking-capacity fuses. The fuse rating should be1.6 to 1.8 times the nominalcurrent of the capacitor. Magneticshortcircuit releases should beset to between 9 and 12 timesnominal current to prevent themresponding to high inrushcurrents.

a Switching

When a capacitance is switched toan AC system, the result is a resonant circuit damped to a greater or lesser degree. In addition to thenominal current, the capacitor accepts a transient current that isa multiple of (as many as 200times) its nominal current. Fast switching, low-bounce contactorsshould be used, observing theswitching capacity for capacitivecurrents stated by the producer.Recommended are special capacitor contactors with leading contacts that feature prechargingresistors to damp inrush currents(see chapter 3).

a Discharging

Capacitors must be discharged tomaximally 10% of nominal voltagebefore cutting them in again.This prevents an electric impulsedischarge in the application, influences the capacitor's useful life inPFC systems, and protects against electric shock. The capacitor must be discharged to 75 V or lesswithin 3 min. There must not beany switch, fuse or any other disconnecting device in the circuit between the power capacitor andthe discharging device. EPCOSsupplies capacitor dischargeresistors to all series, or alternative- ly discharge reactors (chapter 6)be supplied.

a Use in networks withharmonics

Harmonics are produced in theoperation of electric loads with anonlinear voltage/current charac- teristic (eg rectifiers and invertersfor drives, welding apparatus anduninterruptible power supplies).Harmonics are sinusoidal voltages

and currents with higher frequencies of a multiple of the 50 or 60 Hz line frequency. In low- voltage three-phase systems the5th and 7th harmonics are especially troublesome. Detuned capacitors should be used for power

factor correction in systems sub- ject to harmonics. These represent a series resonant circuit of power capacitor and reactor. The circuit istuned so that the series resonant frequency is below the harmonicsappearing in the system. This produces an inductive response to allfrequencies above the series resonant frequency, avoiding reso- nances with system inductances.Depending on the selected seriesresonant frequency, part of theharmonic current is taken up by the detuned power capacitors.The remainder of the harmoniccurrent flows into the superordi- nate system. The use of detunedpower capacitors thus contributesto reducing voltage distortionthrough harmonics and lessensthe disturbing effect on proper operation of other electric loads.

a InstallationSpecifications like VDE 0100, VDE

0101, VDE 0560 part 4 and 46,

EN 60831 and IEC 831 apply to

the installation and operation of

power capacitors. They should be

sited in cool and well ventilated

locations away from other heat-

radiating elements. Natural heat

dissipation is generally sufficient for cooling purposes if enough air

is able to flow to and away from

them and the capacitors are

spaced at least 50 mm apart.

Otherwise, in a less well ventilated

environment, forced cooling (fans)

will be necessary, scaled so that

the maximum admissible ambient

temperature is not exceeded.

– undervoltage detection– overvoltage detection– low measurement current – exceeded measurement current

– insufficient capacitor output – harmonics limits– over temperature

a Principle

The new, microprocessorized (fast 16 Bit processor) PROPHI is usedfor power factor correction in thelow-voltage sector. It features intelligent control and an LCD display with indication of harmonics andnumerous other parameters.

The single-phase, electronicmeasuring system detects thereactive and active component of the network through the current and voltage path. From this it calculates the phase shift betweenthe fundamentals of current andvoltage and compares this to theset target power factor.

If there are deviations, capacitor stages are cut in and out by theoutputs. This contactor control isoptimized so that the desired cos ϕis achieved with minimum switching operations.

Application

Short circuit protection

Advantage:

a Easy replacement

Equipment and systems need tobe safeguarded so that they pre- sent no danger to persons or theenvironment in the event of adefect or failure. This protection isalso important so that all thefunctions of equipment or systems become available again asfast as possible after a defect or failure. Possible solutions arefusible cutouts (exchangeable) or automatic circuit-breakers.

Types of protection

Fuse elements must meet therequirements of the major interna- tional standards and recommenda- tions, eg IEC 947-1, 947-2, 947-3and 947-4, EN 60947-1 and60947-2, VDE 0660T107,CSA C22.2, UL 1077 and JIS.Equally important are thosestandards concerning climaticrequirements.

Personal protection

Integrated personal protection (eg

IP54) is defined by EN 60529 andDIN 40050 and also applies tofuse elements.This also covers protection against foreign bodies (graded by the first digit) and the ingress of water andmoisture (second digit).

HRC-Fuses

aHRC-fuses do not protect a capacitor against overload - they are for short-circuit protectiononly

a The HRC fuse rating should be1.6 to 1.8 times nominal capacitor current

a Do not use HRC-fuses for switching (risk of arcing!)

Features

a Excellent damping of inrush current a Improved power quality (eg avoidance

capacitor contactor a Soft switching of capacitor and thus

better useful life

a Enhanced mean lifetime of PFC systema Reduced ohmic lossesa Rugged terminalsa High temperature stability

a Principle

Only devices specially designedfor the purpose should be used toswitch PFC capacitors. Capacitor contactors should be designed toavoid contact bounce and theresulting high transients. Theinrush currents must be limited toless than the nominal current of the contactor and the capacitor.

In modern PFC capacitors, highpower density and reduction of losses have led to low inductanceand small series resistances.Circuits of capacitors, especially the parallel connection of capacitors that are already activated,lead to extremely high inrushcurrents (> 200 x IN). This has anegative effect on the useful lifeof both contactors and capacitors,besides degrading the power quality in a network.

In capacitor contactors withprecharging resistors, theseresistors are switched by leadingauxiliary contacts. The auxiliary contacts close before the maincontacts and precharge the capacitor. This significantly reduces highinrush currents on the capacitor.

Features

a Excellent damping of inrush current a Improved power quality (eg avoidance

of voltage sags)a Longer useful life of main contacts of

capacitor contactor a Soft switching of capacitor and thus

better useful life

a Enhanced mean lifetime of PFC systema Reduced ohmic lossesa Leading contacts with wiper function

Capacitor contactor for switching detuned and conventionalthree-phase capacitors

a Principle

When a capacitance is switchedto an AC system, the result is aresonant circuit damped to agreater or lesser degree. In addition to the nominal current, thecapacitor accepts a transient current that is a multiple of (as many as 200 times) its nominal current.Fast switching, low-bounce contactors should be used.

Because of the leading contacts,the inrush current spikes (reversecharging operations) are limited or damped by resistance wires. Thesecurrent spikes would lead to welding of the contactor's main contacts and they are also harmful for the capacitors. Reduction of theinrush currents also avoids transients and voltage sags.

Leading contacts with a wiper function are used in these capacitor contactors, ie each leadingcontact is linked to the contactor yoke by a permanent magnet. Theleading contacts close before the

main contacts and open when themain contacts are with certainty closed. This feature of the capacitor contactors guarantees effective, stable operation throughout useful life. The single controlledleading contacts also enhanceresistance to soiling during operation.

The capacitor contactors aresuitable for direct switching oflow-inductance and low-loss capacitor banks (IEC 831, VDE 0560)with or without detuning reactors.They feature leading auxiliary

switches and damping resistors toreduce peak inrush to < 70 * I in(inrush current).The capacitor contactors are weldresistant up to a possible peak inrush current of 200 x Iin. Thebackup fuses gL (gG) should bescaled for 1.6 to 1.8 * Iin. All capacitor contactors come withan auxiliary contact (normally open).

9.2. Antiresonance three-phase filter reactor

Features

a High resistance to harmonicsa Very low lossesa High linearity to avoid choke tilt a Low noisea Simple mountinga Long useful lifea Temperature protection (NC contact)

a Principle

Electrical energy is a significant production factor for industry,and its efficient use should be aprimary objective. Reducing thereactive current component by PFC correction helps to saveenergy.The increasing use of modernpower electronic apparatus(drives, uninterruptible power supplies, etc) that produce nonlinear current influences andloads the network with harmon-

ics (line pollution).

The power factor correction or capacitance of the power capacitor forms a resonant circuit inconjunction with the feedingtransformer. Experience showsthat the self-resonant frequency of this circuit lies typically between250 and 500 Hz, ie in the regionof the 5th and 7th harmonics.Resonance can lead to the follow- ing undesirable effects:– overloading of capacitors,– overloading of transformers and

transmission equipment,– interference with metering and

control systems, computers andelectrical gear,

– resonance elevation, ie amplifi- cation of harmonics,

– voltage distortion.

These resonance phenomena canbe avoided by connecting capacitors in series with filter reactors.Detuned systems are scaled sothat the self-resonant frequency isbelow the lowest line harmonic.The detuned PFC system is purely inductive seen by harmonics abovethis frequency. For the 50 Hz linefrequency, the detuned systemacts purely capacitively, thuscorrecting the reactive power.

GeneralPhaseCap capacitors in cylindricalaluminum cases were designedfor power factor correction inlow-voltage plant. Loads likemotors and transformers consumeactive power as well as reactivepower. Generators, supply cablesand other electrical distributionequipment, in turn, should berelieved of reactive power. TheMKK (metalized plastic compact) AC series (> 2.5 to 30 kvar) isintended to increase packing density per bank and cut component costs. Improved thermal responseand simplified installation areadvantages of the cylindricalaluminum case.

Technical Data

The compact PhaseCap capacitor isa self-healing, metalized polypropylene film capacitor. The current- carrying metal layer (electrode) isvapor-deposited onto one side of the film.

Compact design – low height,weight and volume

Three electrically separated, partialcapacitors are wound concentrical- ly in a single operation onto aninsulated metal core tube, whichguarantees excellent winding precision. The electrodes are connected by metal spraying the face endof the winding element. The partialcapacitors are star, delta or seriesconnected.

The compact MKK winding elements are housed in a cylindricalaluminum case and hermetically sealed by a press-rolled metal lid.

Triple safety system

a Dry technology: instead of aliquid impregnating agent, thecapacitor is filled with gas. So

there is no risk of fire caused by spurting or leaking oil. Dry design is a must for ecologically sensitive applications and insur- ance follow-up.

a Self-healing: the capacitor repairsitself after overload.

a Overpressure disconnector: thisprevents the capacitor frombursting at the end of its usefullife or through electrical or thermal overload.

Innovative and reliable SIGUT ®

connection technology

SIGUT terminals ensure reliable andstraightforward connection, even ina parallel capacitor circuit, withbenefits likea simplified parallel connection of

Extended useful life of115,000 operating hours

After a long drying phase in a highvacuum to eliminate moisture fromthe active element, the capacitor isimpregnated. The case is filled withinert gas and sealed. Then routinetest are performed for gas leakage.

This production process helps toavoid oxidation and partial dis- charges (corona effect), promotingcapacitance stability over anextremely long period, an essential

in filter circuit applications.

High inrush current withstandcapability is crucial

Capacitors used for power factor correction undergo a lot of switching operations. The high inrushcurrents that go along with thismust be handled without degrading useful life. The pulse strengthof this technology comes in partic- ular from the enlarged, sensitivecontact area (improved metalspraying). The breakthrough camewith a Siemens patent called thewavy cut, plus heavy edge film

design. PhaseCap capacitors caneasily handle inrush currents of upto 200 times rated current.

GeneralThe new PhaseCap HD series is afollow-on development of the MKK AC series, covering the power range above 25 through 60 kvar with just one capacitor in acylindrical aluminum case. ThePhaseCap HD is especially intend- ed for heavy-duty industrial applications with extreme demands for useful life, constant capacitanceand high inrush current withdstandcapability.

Such applications require typical

power steps of 25 or 50 kvar switched by a PFC controller viaeach capacitor contactor. The for- mer series was limited to 25 kvar.The new MKK AC series was devel- oped to increase packing density per bank and cut component costs.

This is a first-time implementationof 60 kvar with only one capacitor in a cylindrical aluminum case,improving thermal response andsimplifying installation.

Technical Data

High inrush current withstandcapability is crucial

Capacitors used for power factor correction undergo a lot of switching operations. The high inrushcurrents that go along with thismust be handled without degrading useful life. The pulse strengthof this technology comes in partic-

ular from the enlarged, sensitivecontact area (improved metalspraying). The breakthrough camewith a Siemens patent called thewavy cut, plus heavy edge filmdesign. PhaseCap HD capacitorscan easily handle inrush currents of up to 200 times rated current.

And where it is crucial

a Parallel connection of capacitorsa Non-detuned capacitorsa Capacitor banks using standard

contactorsa Restoration after voltage

interruptions and brownouts

Extended useful life of130,000 operating hours

After a long drying phase in a highvacuum to eliminate moisture fromthe active element, the capacitor isimpregnated. The case is filled withinert gas and sealed. Then routinetest are performed for gas leakage.

This production process helps to

avoid oxidation and partial dis- charges (corona effect), promotingcapacitance stability over anextremely long period, an essentialin filter circuit applications.

The compact PhaseCap HD capacitor is a self-healing, metalizedpolypropylene film capacitor.The current-carrying metal layer (electrode) is vapor-deposited ontoone side of the film.

Compact design – low height,weight and volume

The entire capacitor is composed of three single-phase element stacks.The electrodes are connected by metal spraying the face ends of thewinding elements. The capacitor

elements are delta connected. Thewinding elements are housed in acylindrical aluminum case andhermetically sealed by a press-rolledmetal lid.

Triple safety system

aDry technology: instead of aliquid impregnating agent, thecapacitor is filled with gas. Sothere is no risk of fire caused by spurting or leaking oil. Dry design is a must for ecologically sensitive applications and insur- ance follow-up.

a Self-healing: the capacitor repairs itself after overload.

a Overpressure disconnector: thisprevents the capacitor frombursting at the end of its useful

life or through electrical or thermal overload

Innovative and reliable SIGUT ®

connection technology

SIGUT terminals ensure reliable andstraightforward connection, evenin a parallel capacitor circuit, withbenefits likea simplified parallel connection of

input ends in series,a protection against electric

shock hazard (IP20 to VDE 0106part 100),

a additional connection of discharge resistors for extra reliability and safety,

aclamping device to prevent loosening of screws,

a cable cross-sections up to35 mm2.
