Question

Quizplus · Accepted Answer

Open circuiting the inactive winding prevents circulating current due to transformer action between the idle winding and the energized winding, which can cause overheating and damage to the transformer. Open circuiting the inactive winding helps to prevent circulating current due to transformer action between the idle and energized winding, as the circuit is broken and the current cannot flow through the inactive winding.

The Inactive Winding Must Be Open Circuited To_____________ Circulating Current
