Protection Relays For Industrial Use Contact Load: Low Power

Protection relays are specialized electronic devices used in the electrical power system to protect equipment and prevent power outages. They are used to detect and isolate faults (such as over-current, over-voltage, and short-circuit) and to trigger the appropriate protective action, such as opening a circuit breaker or disconnecting a portion of the electrical network. Protection relays are critical components of a power system as they help ensure the stability and reliability of the electrical grid by quickly detecting and mitigating faults. There are various types of protection relays, each designed for specific protection functions, such as over-current, over-voltage, under-voltage, and earth-fault protection. These relays are essential for ensuring the safe and reliable operation of electrical power systems.
