CPRI DEVELOPS DIGITAL AC PEAK - PEAK/Ö2 METERFOR HIGH VOLTAGE AC MEASUREMENT
Background:
For carrying out di-electric tests withalternating voltage, as per Internationalstandards, the value of the test voltage isdefined as its peak value divided by Ö2.Generally the test voltage is beingmeasured with ordinary meters which readsr.m.s value which is nothing but Peak//Ö2.But this is true only for a pure sine wave.Hence the standard also specifies that theratio of peak to r.m.s value of the testvoltage shall be equal to Ö2 times within± 5%.
The costs of AC measuring instrumentsfulfilling the above requirement of IEC60060-1 & 2 are high and there are veryfew people to develop these instrumentsacross the Globe. Considering this fact,High Voltage Division of CPRI decided todevelop such instruments with their vastexperience in commercial testing in highvoltage laboratory and also with theexpertise available in house.
Introduction:
The Measuring Instrument developed byCPRI can be used in association with anyhigh voltage AC divider. It has a uniquefacility to check the performance of theinstrument and also to verify the quality
of the input voltage according to thestandard.
Design Aspects:
The development of this measuringinstrument consists of the following:
1) Precision Input Attenuators:
Apart from the system divider, preciseattenuator with necessary frequencyresponse is required to limit the inputvoltage to the acceptable limits of theADC. This instrument is designed insuch a way that it directly reads theinput voltage in kV if the externaldivider ratio is 1000. Otherwise theinstrument can be tuned to suit theratio of any existing divider.
2) Measurement Circuitry:
A custom built circuit has beendeveloped to suit the norms specifiedby IEC 60060- 1 & 2.
3) Electric and Magnetic Fieldinterferences:
Since this measuring instrument hasto work in the field of few hundredkilovolts, the instrument has to beprotected for electric and magneticfields. Enough care is taken to combatwith this problem.
4) Ultra Isolation Input:
The operating voltage of theinstrument has been supplied throughan Ultra Isolation transformer toprotect from any surges from thesupply.
5) Performance Check for theinstrument:
This is a unique facility to check theperformance of the instrument in bothPeak mode and Peak/Ö2 mode.When the cal button is pressed inPeak mode the display will read 100and in Peak//Ö2 mode the display willread 141.4 confirming theperformance of the instrument.
6) Input Voltage Quality Check:
By measuring the input voltage inboth Peak mode & Peak//Ö2 modethe quality of the input voltage canbe verified by taking the ratio of both,which should be Ö2 ± 5% accordingto the standard.
Specifications:
A) Operating Voltage 230 V ± 10%
B) Maximum Signal Input 200 V ACPeak
C) Input Connector BNC
D) Display 3 ½ Digit DPM
E) Resolution 0.1 kV
F) Frequency Response 10 Hz to 500Hz
G) Measurement Options Peak & Peak/ Ö2
H) Built in Performance check.
Testing of Hardware:
The instrument has been tested at HighVoltage Laboratory of CPRI, Bangalore.The performance of the instrument is onpar with any imported measuringinstrument.

FREQUENCY RESPONSE ANALYSIS (FRA) A TOOL FOR CONDITION BASED MONITORING OF
YOUR VITAL ASSETS (POWER TRANSFORMERS)
method for detecting mechanicaldeterioration in power transformers.
FRA is not an absolute method, but amethod of comparison. Three evaluationprocedures can be used for detectingmechanical windings displacements inpower transformers. They are time- basedor finger print comparison, construction-based or symmetrical phase comparisonand type- based or sister unit comparison.If any significant deviations in the resultsoccur, the transformer is faulty andappropriate action has to be taken.Inclusion of FRA measurement in routinetest protocol on an assembled transformerat the time of manufacturing in the factorycan also provide confidence on theworkmanship and mechanical integrity ofthe transformer.
CPRI is carrying out FRA measurements atsite using Sweep Frequency ResponseAnalyzer. The test method requires a 3-lead approach, with the leads providingsignal, reference and test response.Measurements of voltage ratio is carriedout by applying input voltage to oneterminal with output voltage obtained atanother terminal of windings with all otherterminals either open or earthed. Frameor transformer tank is always earthed. Theinstrument has inbuilt processor for datastorage, processing and display. Theinstrument basically comprises of ananalog sweep frequency voltage source,which gives constant magnitude output of10Vp-p at 50 ohms, for a frequency rangeof 10Hz to 10MHz and has two measuring
Power transformers are the mostexpensive and strategically importantcomponent of any power generation andtransmission system and their failure is avery costly affair. Power utilities strive toincrease the life period of a transformerand to decrease their life cycle cost. Thiscan be achieved by using intelligentcondition monitoring and diagnostictechniques. The choice of diagnosticmethod and instrumentation depends onthe nature and type of the fault to bepredicted. When a transformer is subjectedto electro-dynamic stresses originatingfrom magnetic forces caused by externalshort-circuit currents or excessivemechanical accelerations during transportwinding deformation / movements result.Power utilities are interested to detectmechanical and electrical damages ontransformer in service. Monitoring anddiagnostic techniques, which can evaluatethe integrity of a transformer, are essentialto evolve optimum and better reliabilityof the equipment.
Conventional condition monitoringtechniques such as thermal monitoring, oilanalysis, partial discharge measurements,recovery voltage measurements etc areunlikely to detect mechanical damage untilit develops into a dielectric or thermalfault. Hence, a specialized technique isclearly required for the monitoring andassessment of mechanical condition. Thereis no traditional method, which is efficientenough to detect the deformation.Frequency Response Analysis (FRA)technique can be a successful diagnostic
channels thatsimultaneously samplethe input signal. Theinstrument is suited foron site and has asuperior signal to noiseperformance at thehigh frequencies,which is considered tobe important for thedetection of windingmovement.
CPRI has carried outFRA field measure-ments on number of
transformers for various utilities likeNALCO, WBSEB, KIRLOSKAR, BHEL, DELHITransco etc. Presently CPRI has work ordersfrom NHPC, Manipur and VTPS, AP Gencofor conducting FRA measurements at theirrespective sites. CPRI has the requiredexpertise to conduct the measurements,interpret and diagnose the results. FRA isconsidered to be very sensitive to detectthe changes in the transformer structureand hence useful in assessing the state ofhealth of the transformer with regard toits mechanical integrity and feels that itshall be included as a routine diagnostictool for carrying out measurements onlarge power transformers 1) Atmanufacturers works 2) beforecommissioning the unit at site and 3) as apart of test schedule for condition basedmonitoring as required from time to timefor the existing aged units. Photographicview of a 30-year-old 160 MVA, 220/132/33kV, Autotransformer undergoing FRAmeasurement at site is given in Figure. Atypical FRA magnitude plot for all commonwindings of this shell form typeautotransformer is given in Figure. Basefingerprint frequency responses, ifavailable, will be useful to diagnose thedisplacement/ deformation of a particularwinding. In the absence of fingerprints ofthis transformer, comparison of frequencyresponses among the different phasewinding indicated integrity of the windingstructure with respect to each other.Subsequent FRA measurements can usethese responses as base for assessingwinding displacement/ deformations infuture.
