I have a 2500 KVA transformer, 12,470 V to 480 V Delta to Wye which was showing a negative 4 PSI vacuum with the guage needle bouncing noticeably. It is now showing negative 7.6 PSI.
The temperature has warmed up and the pressure should have gone closer to 0 rather than further to the negative.
I am concerned there may be a leak which could contaminate the oil in the tank. If there was a leak the pressure should have gone closer to 0.
The transformer is operating at approximately 2800 Amps and the maximum Amps is 3008 so 93%. Outside temperature was plus 8 C.
Are there any thoughts on this situation our there?
Any information would be appreciated.
