An Overview on Detection of Temporary Fault and Permanent Fault for 3 Phase Load

Abstract

Abstract: To Maintain reliability in Power System it is important to protect the 3 phase devices like inductive, resistive, etc against various faults occurring in it. This fault should be identified and analysed quickly for their remedies. The Project Aim is to develops an Automatic Tripping mechanism for the three-phase system. In the case of a temporary fault, the output of the project resets automatically within second. While in event of Permanent fault condition the permanent Trip. Due to these faults, the power system may suffer from considerable damage. This can lead to disturbance in power supply and may cause a standstill to various industries linked to the system. In a three phase power system, these faults are classified as LG (Line to Ground), LL (Line to Line), 3L (Three lines). This system can overcome such problem which by sensing the fault automatically and disconnects the system from the supply so that large scale damage to the system equipment can be avoided. The system automatically differentiates between a temporary disturbance and a permanent fault and appropriately cuts the supply for a short duration or long respectively. The purpose of this project is also to send the information to the mobile by using Global system for Mobile Communication (GSM) technology.
