Design & Implementation of Three Phase Fault Detection And Protection

Abstract

The project involves creating an automatic tripping mechanism for the three-phase transmission system. In the event of a transient fault, the project's output resets, however in the event of a permanent malfunction, the output obtains the permanent trip state. Several problems can occur in a three-phase power supply system that serves industrial and residential consumers. These failures are the result of some defects, which can be transient or permanent. These flaws could cause significant damage to the electricity system. This can disrupt power delivery and cause a halt in numerous industries connected to the grid. In a three-phase electrical system, these faults are categorized as LG (Line to Ground), LL (Line to Line), and 3L (Three lines). This system may solve such a problem by automatically identifying the failure and disconnecting the system from the power source, preventing large-scale damage to system components. The system automatically distinguishes between a brief disruption and a permanent malfunction, and cuts the supply accordingly for a short or lengthy period of time.
