An ice plant has a load of 100 KVA, 3 Phase 80 percent power factor lagging. To be able to serve this load, two single phase transformer are to be connected open delta. What is the minimum KVA rating of each?

A 10 MVA three phase load is to be served by a three phase transformer at aline voltage of 13.8 kV. The supply side voltage(line-line) is 138 kV. Varioussingle phase transformers are available in the warehouse but all havewindings with voltage ratings under 100 kV and current ratings under 250 A.Is it possible to serve the load using only three single phase transformers? Ifso, specify the three phase connections and the low and high voltage ratingsof the single phase transformers.

Whats the primary line current for delta/wye 480v to 120/208v, three-phase transformer that has secondary line current of 200A?
