Thanks for your input as you were correct on the 480X208/120 and the average current was @ 60 amps per phase. The transformer seems to be about 60% loaded and has been there since 1999. I am perplexed as to how the primary current can shoot up without tripping anything on the secondary side. Looking at the numbers for the current would suggest to me locked rotor current or a fault in the transformer or its feeder, and I am leaning toward the latter and is why I need information on the procedure for megging said 75 KVA dry type. Any info on this or any other input would be greatly appreciated.
Thanks,
Watthead
