Three-phase energy meter field calibrator
3.2 Check the active and reactive power of energy meter at the same time
The calibrator simultaneously measures the active and reactive error of energy meter.
For example: Three-phase three-wire electronic energy meter 3 × 100V, 5A clip-on ammeter
input, the active constant of the energy meter is 8000r/kW.h, and the constant of rewatt-hour meter
is 8000r/kvar.h. If the photoelectric calibration method is used, the number of active turns is 3, and
that of reactive turns is 2.
