Iron losses are negligible during short-circuit test of transformer since
Iron losses are negligible during short-circuit test of transformer since
- The current on secondary side is negligible
- Full-load current is not supplied to the transformer
- The voltage on secondary side does not vary
- The voltage applied on primary side is low
Correct answer: 4. The voltage applied on primary side is low
