Whether you prefer to install a transformateur a sec [dry transformer] or oil cooled transformer following are few preparations that will be needed.

  • Standard or special transformer tests

There are number of tests performed on the transformer before they are to be installed which are standard set of testing. Also, there are few special tests also need to be performed as specified by the manufacturer.

  • Site considerations

Necessary site preparation has to be done so that the transformer can be safely installed and all the safety codes that are recommended must be ensured. Transformer should not block any traffic movement if it is installed in outside location.
