THREE PHASE TRANSMISSION LINE  FAULT DETECTION AND  ANALYSIS SYSTEM

The Electric Power System is categories into many different sections. One from that is the transmission system, where power is transmitted from generating stations to substations via transmission lines into consumers. Both methods could operate various types of malfunctions is usually referred to as a “Fault”. Fault is simply defined as a number of undesirable but unavoidable incidents can temporarily disturb the normal condition of the power system that occurs when the insulation of the system damaged at Particular point. Moreover, if a Conducting object comes in contact with a open power conductor, a short circuit, or fault, is said to have happened. The causes of faults are many, and they include lighting, wind damage, trees falling across transmission lines ,line fall on building, vehicles or aircraft colliding with the transmission towers or poles, birds shorting lines or vandalism. In this study, the causes and effects of faults in the overhead transmission lines was the focus of the research. Some of the many reason of faults and some located methods will be discussed. These faults lead to substantial damage to the power system equipment and high voltage In India it is common, the faults might be LG (Line to Ground), LL (Line to Line), 3L (Three lines) in the normal supply systems and these faults in three phase supply system can be affect the power system
