Early identification of procedure flaws can help keep away from anomalous occasion movement. Fault identification can be cultivated through different methods. This paper displays the writing review of real techniques and ebb and flow condition of research in the field with a determination of essential commonsense applications. Key Words: fault, staggering expense, different methods, ebb. 1. INTRODUCTION This paper speaks to the Line Protection on the utilizations of fault location innovation. This tends to the recognition of those irregular conditions where a conductor breaks and does not contact either another conductor or a grounded component. Recognition of fault on line is finished via mechanization. As fault examination wound up imperative prerequisites of the electric power framework to wind up progressively exact. There are mixes of an electrical switch and a transfer security framework in a run of the mill fault cleaning framework. The primary parts in security framework are wiring, transducers, assistant power supply, switches, circuit breakers, transfers and the working loop of the electrical switch. Prior fault is naturally cleared by electromagnetic transfers. The electrical amount, which is voltage or a flow, was changed to a mechanical power which worked the transfer when a preset edge was surpassed. However at this point a days the strong state transfers are grown with the goal that the activity can be performed effectively and precisely. 1.1 TYPES OF FAULTS There are mainly two types of faults in the electrical power system. Those are as following: 1.
Symmetrical
2.
Unsymmetrical faults.
This technique is used to reach a strong conclusion of the power grid monitoring & controlling without manpower is SCADA. 1.
Symmetrical faults: These are very severe faults and occur infrequently in the power systems. These are also called as balanced faults. There are mainly two types namely 1. Line to line to line to ground (L-L-L-G) and 2. Line to line to line (L-L-L)
Three phase fault analysis or information is required for selecting set-phase relays, rupturing capacity of the circuit breakers and rating of the protective switchgear. 2.
Unsymmetrical Faults: These are very common and less severe than symmetrical faults. There are mainly three types namely 1. Line to ground (L-G), 2. Line to line (L-L) and 3. double line to ground (LL-G) faults.
