Abstract - Now-a-days the demand of electricity or power are increases day    by day this results to transmits more power by Increasing the transmission line capacity from one place to the other place. But during the transmission some faults are occurred in the system,  such as L-L fault (line to line), 1L-G fault (single line to ground) and 2L-G fault (double line to ground). These faults affect the power system equipment’s which are connected to it. The main aim of this paper is to study or analysis of faults and also identifies the effect of the fault in transmission line along with bus system which is connected to transmission line. Mainly the major faults in long transmission lines is 3 Phase fault which are harmful to the  electrical equipment. A proposed model in transmission line is simulated in MATLAB software to analysis and identified the faults and limit the fault. Fault block was taken from the  sim-power system block library.The whole modeling and simulation of different operating and different conditions of fault on transmission line on IEEE 14 Bus System, their faults three line short circuit of the proposed work is presented in this paper.
