A ________ is a transformer with separate primary and secondary windings wrapped around a laminated core.

A. Wound Current Transformer
B. Window current transformer
C. Bushing Current transformer
D. Ring current transformer

Answer: A. Wound Current Transformer

Explanation:
  • A wound current transformer is a transformer with separate primary and secondary windings wrapped around a laminated core.
  • For this type of transformer, the primary winding of more than one turn is wound upon the core and provides the primary section of the transformer.
  • Such primary winding is so designed that it could be able to carry the short-circuit current of the system.
  • According to the design and turn-ratio requirement, the secondary winding is accordingly wound to provide the required current on the secondary circuit of the system.
