So the power company upgraded me to a 50 KVA transformer after the 25 KVA exploded. I am running 200 amps at 120v constant. Anyone know if this is safe on that size transformer? I dont want to blow another one, they will charge me a ton of money.
How long have you been running the 25 KvA one?
If you have been running it for a long time, then there shouldn't be much risk.
But if it happened the first time you used, then you might want to do the power calculation.
