Transformer insulation resistance measurement

transformer insulation resistance measurements

The transformer copper loss refers to the loss which at the beginning of the secondary wire DC resistance creates, therefore only needs the transformer on to add on the nominal current then, the concrete operation is the secondary coil direct pipe nipple, adds the voltage on a side, amounts to until
