The burden is defined as the load connected across its secondary potential transformer.
The burden is specified as VA.
The burden in PT is given by:
\(R_{Burden}={V_{out}\over I_{sec}}\)
The rated burden of a PT is a VA burden that must not be exceeded if the transformer is to operate with its rated accuracy.
From the above explanation, we found Both A and R are true and R is the not the correct explanation of A.
