Major Performance of best current transformer
●Power frequency withstand voltage
The power frequency withstand voltage of the primary winding to the secondary winding and the grounding shell and the secondary winding to the ground shell is 3kV, and the experimental time is 5min. There is no damage to the insulation and no discharge phenomenon on the surface
●interturn dielectric strength
The secondary winding is open, and the primary winding is open to expand the rated current and maintain for 1min. The insulation between turns of the secondary winding of the transformer is not damaged
Environmental conditions of utility current transformer
●The highest temperature does not exceed 55℃, and the daily average does not exceed 35℃
●Daily average humidity is not more than 85%, monthly average h…
