Power Factor Meters
The Laboratory can provide calibration for 50 or 60 Hz single-phase power factor meters with measuring range from zero to unity, leading or lagging.
Calibration will be made by applying appropriate sinusoidal voltage and current signals with known phase relationship to the meter under test. The ranges of test voltages and currents are 25 V to 250 V and 50 mA to 100 A respectively.
