*Voltage & Current Measurements

Measured voltage signals are obtained through collecting and processing, and the true

RMS of 3 line_line voltage or phase voltage is displayed on the screen of PMC16.we

adopt direct input if the measured voltage is 0.4KV, and use voltage transformer as

input if the measured voltage is 0.69KV-35KV.

PMC16 allows for a voltage measurement of up to 999999V.

Measured current signals are obtained through collecting and processing, and the true

RMS of 3-phase current is displayed on the screen of PMC16.we adopt direct input if

the measured current is no more than 5A,and use current transformer as input if the

measured current is above 5A.

PMC16 allows for a current measurement of up to 32000A.

The secondary circuit current of the zero-sequence current transformer used in zero-

sequence current measurements is0.02-1A. Measured current signals are obtained

through collecting and processing, and the trueRMS of zero-sequence current is

displayed on the screen of PMC16.
