Good morning everyone,
I am upgrading a facility that is changing from using hydraulic motors to electric motors, lighting and instrumentation. The facility is currently fed from an outside padmounted 500 kva 12.47v/480v transformer. In order to save money I have been instructed to try to keep all the loads within the 500 kva range.
Here's my dilemma:
The outdoor transformer also feeds another building (small building) to a 480v/208v 75kva transformer. My total kva load with both buildings is 442 kva. However when I add 1.25% diversity I get 553 kva which is over the 500 kva. Is it unethical to keep this transformer or should I just bite the bullet and add the next higher transformer? I didn't know whether I'm within an operating range of a 500 KVA transformer? I think I'm too far out of the range.
Thanks
