Question

High leakage transformers are of 

A.

Small voltage ampere rating

B.

High voltage ampere rating

C.

High voltage rating

D.

Low voltage rating

Answer ( Option A)

Small voltage ampere rating

Solution

Leakage transformers are such transformer in which magnetic flux of the secondary is loosely coupled to the flux of the primary.

●This loose coupling ensures that the transformer can withstand short circuit conditions.         

●They are used in extra low voltage area where short circuit conditions are expected and the voltage ampere rating is small.       

&Key Points:-

Transformers are also known as stray field transformers.
