Three winding transformer commissioning test sheet
(OP)
Can someone please post/mail me a typical commissioning scedule for power transformers including all transformer tests and functional tests.

If in MV also has NLTC, for having a benchmarking test the contact resistance of all taps (usually 5 taps)
IEEE-STD 62-1995 (I think so) is a good reference.
Insulation power factor including capacitance test is advisable also.
This tests will be important as zero test (benchmarking) for future diagnostics.
