FLUKE 5500A Calibrator Multifunction Standard for Calibration of Digital Multimeters SPECIAL FEATURES

I. Precision Static Energy Meter Calibration
The Laboratory is regularly calibrating and certifying Precision Static Energy Standards like
1. L & G make TVE 102 / E (Class 0.05 
2. Schlumberger make SM 3050 (Class 0.07)
3. Zera, TPZ 303 (Class 0.02)
by using Three Phase Power and Energy Calibration Standard ROTEK, Model 8000 – 3P having an accuracy of 0.01% and Standard Watt-Converter Model ROTEK MSB 001 A having an accuracy of 0.005%. Various Electricity Boards in the country such as MSEB, MPEB, GEB, Goa Electricity Board, KSEB, NTPC, BSES, BEST, Grid Corporation of India and several other private organizations are availing these facilities to calibrate their Energy Standards.

II. Harmonic Analysis
Electrical Calibration Laboratory is having large experience to carry out the Harmonic Analysis in Carbon, Chemical, Cement, Still & all other Continuous Process Plants. Harmonic Analysis is carried out by using DRANETZ ENERGY ANALYSER MODEL 8000-2 having harmonic analysis option HUR - 50. Following are the features of the Harmonic Analyser:
1. Measurements made easy by clamp-on CTs
2. No shut down for continuous Process Plants
3. Sample rate every 5 seconds
4. Instant printouts of data for power line parameters like V, I, W, Vcf, Icf, Vthd, Ithd PF etc.
5. Printout of phasor diagrams and wave shapes
6. Measurement of Individual Harmonics & their phase angle w.r.t. fundamental.
7. All printout contains the date and time of the measurement.
