Faults often occur in three-phase power systems. With the increasing demand for electrical power, one key challenge is the ability to identify and analyze these faults when they occur.In this paper, the performance of long transmission line in a balanced system has been discussed. This paper is the first in the series of four papers for fault analysis in a three-phase system. A three linesto ground (LLLG) fault occurred in the system, which automatically operated the circuit breakers and left them open.Simulink was used to view the waveforms of the current and voltage at both normal and fault conditions. The result showed that at the fault point, the sudden increase in current was accompanied by a drop in voltage. The system was also able to leave the breaker open all through the operation, suggesting the occurrence of a permanent fault.
