To isolate the transformer from external sources (correct)

Study Notes

Transformers convert AC voltage and current into DC, and vice versa.
Transformers have no rotating parts, so they never run on DC supply.
Transformers convert only voltage and current, and frequency remains constant for all load.
A pressure relief valve protects the transformer from internal fault.
A Bucholz relay protects the transformer from internal fault.
An isolation transformer is used for isolation purposes only.
