4. A REVIEW ON THREE PHASE FAULT ANALYSIS WITH AUTO RESET ON TEMPORARY FAULT AND PERMANENT TRIP

The paper is about a tripping mechanism for a threephase power supply in a power system. After a brief interruption in the event of a temporary fault, the project output resets. A permanent fault causes tripping condition. Because of temporary or permanent faults,electrical grid substation that supplies power to many consumers fails.The fault has harmed powering the system's equipment. It is quite common in India. Power supply system faults are LG (Lin to Ground), LL (Line to Line), 31. (Three lines), and faults in three phase systems affect the entire power system. To address the issue, a system that detects faults and automatically disconnects the power supply is being developed in order to avoid large-scale damage to control gears.
