We have isolation transformer 25kvA & ONLINE UPS 15KvA
(3PHASE I/P,3PHASE O/P)where isolation should have
connect,before UPS or after please brief.
It should be connect before the Input Filter of the UPS..
Pls have a look on this Circuit Diagaram:-

I have calculated load for an office building which is 1200 KW as all the load is single phase therefore its 1200 kw single phase. Now i have to design Transformer and Generator for this load Please kindly give me exact answer that how much capacity of Three Phase Transformer and Three Phase Generator is required for this load.
We all have seen transmission and Distribution lines In transmission lines the voltage is high and current is low(to reduce I^2r loss) and in distribution lines voltage is low but current is high however the size of transmission wires is bigger than that of distribution wires even though the amount of current carried by the distribution lines is more than that of transmission lines why?
