Fault Analysis of Three Phase Using Auto Reset for Temporary Fault and Trip for Permanent Fault

In power systems, faults are common occurrences that can cause disruptions in the supply of electricity, leading to downtime and significant economic losses. Fault analysis is critical in identifying the root cause of these faults and developing mitigative measures to prevent further occurrences. In this paper, we present a fault analysis method that uses an auto reset for temporary faults and trips for permanent faults in three-phase systems. The proposed system is based on a microcontroller-based circuit that continuously monitors the system for faults and initiates corrective actions based on the nature of the fault.
