Abstract

There are various methods available for estimation of fault currents in any Electrical Power network or system like per unit and impedance or ohmic methods which are more complex and requires to remember so many formulae. There is a simple method called as Power MVA method in which there is no need to remember any formulae except a minimum basic knowledge of series parallel resistance networks. But the calculations should be so accurate such that the sizing of electrical equipment and proper relay co-ordination can be done by the designer of system. To explain it in detail, a simple practical example from a nearby Industry is taken and estimates are done with Power MVA method. Also same are simulated with a software and the results are compared for their accuracy.
