Q.

During short-circuit test of a transformer, core losses are negligible because

  • Athe voltage applied on the primary side is low
  • Bthe current on the secondary side is rated current
  • Cthe voltage on the secondary side is zero
  • Dfull-load current is not supplied to the transformer
Correct Answer : (A)

the voltage applied on the primary side is low

Hints :

During short-circuit test of a transformer, core losses are negligible because the voltage applied on the primary side is low.
