Here one question my arise that both CT and Power Transformer are Transformers but Open Circuiting CT…

Aim/Purpose of the IR Test: To ensure that, each winding of the Current Transformer, has sufficient Insulation Resistance with respect to Earth (CT Body) and between the two Secondary Cores. Principle: Insulation Resistance is the Ratio of the Applied Voltage (DC) to the total Leakage Current. Leakage current should be as small as possible ,…
