Protective relays are critical components in electrical power systems, acting as the “nervous system” that detects faults and initiates rapid isolation of affected sections. Their primary purpose is to safeguard power system equipment, maintain system stability, and ensure personnel safety by preventing damage and limiting fault propagation.
In modern electrical power systems, integrating Low Voltage (LV) boards with Supervisory Control and Data Acquisition (SCADA) systems is essential for efficient real-time monitoring and control. This process enhances system reliability, optimizes energy usage, and improves operational decision-making.
