PEC-H3A Three-phase Watt-Hours Metter Testing Devices

详情

Check the errors of three-phase Watt-Hour meter active and reactive power at one time, and also check the errors of main meter and sub-meter at one time; Display the following electrical parameters: U, I, P, Q, Φ, F etc. Test CT transformation ratio, showing in waveform; Test 2~*1 harmonic wave of current and voltage; Judge wrong line connection; Test communication baud rate of multifunctional meter and read its number; PT and CT secondary load function; Calibrate transformer’s errors automatically; Able to hold upload and download data (FAT*2 documentation) in Flash disk and update it; Supply power by batteries, supply power and charge online with wide voltage range(*7.7~**0V); Worst case accuracy: ±0.*5%, ±0.1%.Voltage AC *****0V Current Terminal 5A Transformer 5A *0A **0A **0A ***0A transformer 5A *0A ±0.2% (with self-calibrate function) **0A **0A ***0A ±0.5% Constant of electric energy impulse 5A FL=****0P/KWh FH=3.6×*******0P/KWh others FL=****0×5/rated current (P/KWh) FH=3.6×*******0×5/ rated current (P/KWh) Frequency ****5Hz Phase testing range *****-***0º Transformer rate ratio < ±0.5% Voltage influence < ±0.*1% Frequency influence < ±0.*1%(****5Hz) Temperature influence < ±5ppm/ ℃(typical) Variation within *4hours (0.1level) < ±0.*2% (0.5 level) < ±0.*1%
