Do I need to measure DC resistance when current transformer is connected? Why?
There is no such project in the calibration of transformers. Generally not required.
The verification items for current transformers and voltage transformers include:1, appearance inspection2 insulation resistance measurement3. Insulation strength test4, winding polarity check5 basic error measurement6 、 stability test.
The GB1208 current transformer standard is not requiredHowever, the standard GB50150 standard for power system acceptance requires the measurement of one or two direct current resistance
