Please provide a step by step solution to the
problem. Please explain how the problem is solved so I would understand how to solve it. Thank you
Provided: Sbase = 46MVA
Problem: The plant capacity of a 3 phase station consists of two 10000 KVA generators of reactance 12%each and one 5000 KVA generator of reactance 18%. The generators are connected to the station 4.16KVbusbars from which the load is taken through three 5000 KVA step up transformers each having areactance of 5%. Determine the rupturing capacity in MVA in which the circuit breakers on:a. low voltage side of the transformerb. high voltage side of the transformerc. the allowable circuit breaker settings at the low voltage side of the transformer with 5 cycle duty.
