Abstract :
This paper describes a mathematical model of a 25 MVA and 78 kV powerformer that can be used to simulate internal fault waveforms for power system protection studies. The machine equations are solved using a suitable numerical technique in MATLAB. Simulation results showing the fault currents, during a single phase to ground fault and a two phase to ground fault, are presented.
