Test No. 1 and 8 belong to life evaluation tests.As the tr
has been in use, tests No. 4 and 5 may not be necessary.For
Inter-turn short, test No .2 may prove useful if the
previous values are available and magnetic balance test (
No.1 )is really useful.Oil test is just for knowing the
present condition.If the tr has failed within the guarantee
period , we have to take extra care while furnishing the
test results. The firm may put the blame on you,for the
damages for applying the voltages to test.Simple tests and
relay operations are sufficient.It is more difficult to
prove that a tr is healthy by all means.
