A plant consists of two 10 MVA generators of reactance 18% each and two 5 MVA generators of 12% each. All are connected to bus bar to supply a load through three step up transformers of 8 MVA each having reactance of 8%. Determine fault MVA on HV side of any one transformer.

A plant consists of two 10 MVA generators of reactance 18% each and two 5 MVA generators of 12% each. All are connected to bus bar to supply a load through three step up transformers of 8 MVA each having reactance of 8%. Determine fault MVA on HV side of any one transformer.
Answer : To determine the fault MVA on the high-voltage (HV) side of any one transformer, we need to first calculate the total reactance of the system (the combined reactance of all generators and transformers) and then ... Thus, the fault MVA on the high-voltage side of any one transformer is **8.77 MVA**....
