    The type and routine test are very important for transformer. As it checks the quality of material used and the procedure of transformer manufacturing hence provide us details of life of transformer, the transformer behaviour on different faults. As power transformer is highly expensive as well as important part of distribution system. Hence it become important to test them before using it. Along with this the transformer oil testing is also highly important.

    To perform all these test now a latest technique is used SFC (Static Frequency Converter) instead of M-G set because of there low loss, low power requirement. In india only KVTEK is a company manufacturing it.

    When doing the REF test, to bypass the main winding impedence and take only CTs in picture, there’s a method..
    any one can post, how to do the connection..
