Abstract :
In this paper HS Transform has been used for differentiation between inrush and fault current. Fuzzy C mean clustering technique has been used for fault current classification using Parseval´s theorem calculating that energy index for various cases. Simulation of the fault (with and without noise) was done using MATLAB AND SIMULINK software taken 2 cycles of data and 800 samples.
