I am doing a line diagram for the machine shop in earlier threads, and on their only print they have, it shows the sub station and the (2) 4160 services. The first one is cut and dry, it shows a 600Kva 460V dry transformer in the back, but it is really a 600Kva 440V...Not the problem..
The problem lies with the 208V side. There are 3 "pot" transformers making up the service, not 1 big transformer like the 440V side.
The print states, (3) Pot 100kva..
The service has parallel 500MCM pulled in to the MDP.
Is it safe to assume that this really is a 300KVA 208V service? They are additive aren't they?
So this would ponder the thought that a 45Kva 3 ph transformer is really (3) 15Kva cores?
