What are the 5 losses of transformers?
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.

Why are eddy currents undesirable in transformers? Answer : Eddy currents are undesirable in transformers because they cause **energy loss** and **heat generation**, which can reduce the efficiency of the transformer. Here's how: 1. **Energy ... currents. By minimizing eddy currents, transformers can operate more efficiently and with less heat generation....
