Three single phase transformer are balanced delta delta each rated 120 kVA supplying a 3 phase load of 360 kVA. If one of the transformer is removed for repair and the remaining are banked open delta. FIND THE FF: a. the load carried by the remaining transformer b. the KVA overload by the remaining transformer c. the KVA overload in each transformer

A 220-kVA transformer with .2% resistance and 4% reactance and another  120-kVA transformer with 3% reactance and .15% resistance with the same  voltage ratio. the phase angle is 33 degree and the total load .25 MVA. How much the load of each transformer.  what are the load currents of each transformer  if a1 =20 and a2=25?

Three single phase transformers are connected in a Delta-Wye configuration.  Each transformer is rated 13kV/64kV.  The transformers are connected to a 3 phase 13kV (L-L) supply and the balanced three phase load is 788KVA. What is the current magnitude in the secondary winding of each transformer? explain the steps too please

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.
