Protection Relays
Protection Relays: Safeguarding Electrical Systems
Protection relays are specialized devices designed to monitor electrical circuits and equipment, detecting abnormal conditions and taking corrective actions to prevent damage, minimize downtime, and ensure the safety of electrical systems. These relays play a critical role in safeguarding equipment, personnel, and facilities in various industrial, commercial, and utility applications.
Protection relays operate based on preset conditions and parameters, continuously monitoring electrical parameters such as voltage, current, frequency, and phase angle. When abnormal conditions occur, such as overcurrent, under/over-voltage, phase imbalance, or ground faults, the relay activates to isolate the faulty section of the electrical network. This action prevents further damage, mitigates risks, and ensures uninterrupted operation of essential equipment.
