Ground Fault Protection Relays (GFPRs) play a crucial role in modern electrical systems, ensuring both safety and reliability. Electrical faults, particularly ground faults, can cause severe damage to equipment, disrupt operations, and pose significant risks to human life. By detecting and responding to these faults promptly, Ground Fault Protection Relays serve as essential components in industrial, commercial, and residential electrical networks.

    A ground fault occurs when an unintended electrical path is formed between a live conductor and the earth or a grounded object. This situation can arise due to insulation breakdown, moisture, mechanical damage, or human error. When a ground fault occurs, the current flows through an unintended path, potentially causing overheating, fire hazards, or equipment failure. Ground Fault Protection Relays are designed to detect these abnormal currents and isolate the affected section of the electrical system before extensive damage occurs.
