Hello all. I work on a World War 2 era battleship memorial. We had a sizable leak and on of our general lighting transformer banks got wet about 2 inches up. They are three individual single phase 440/120 20 KW transformers wired in a delta configuration. It blew the A and C phase 100 amp primary fuses, the B didn't blow. We are drying them out with heaters and the megger readings from phase to ground are all over 275 on the 1000 VDC scale and rising. The phase to phase readings are 1.2 on A, 0.1 on B, and 1.3 on C, all on the 250 VDC scale for more accuracy. Has anyone ever dealt with such a circumstance? Does it just take a lot of time and heat to dry out water trapped between the windings? Is there anything we should do other than applying heat? Any other suggestions would be welcome.
Thank you very much.
