As we know electricity or electrical power are increases day by day and transmits more electrical power by increasing the transmission line capacity from one sub-station to another sub-station. During some faults are occurred in the long transmission line system, such as single line to ground fault (L-G), double line to ground (2L-G), triple line to ground fault (3LG) and Line to line fault (L-L). These types faults are affecting the electrical power system equipment’s/component which are connect in EHV Transmission line. Mainly the major faults in long transmission lines is (L-G) single line to ground fault which are harmful to the electrical equipment. A proposed model in 300km/440kv EHV transmission line are simulated in MATLAB software to analysis and identified the faults.Fault block was taken from the sim-power system block library. The whole modelling and simulation of different operating and different conditions of fault on EHV transmission line, their faults are L-G fault, 2L-G fault, 3L-G fault and three line short circuit of the proposed work is presented in this paper.
