Overload Relay in Electrical Power Systems An overload relay is a protective device that detects excessive current in an electrical circuit and trips or disconnects the circuit to prevent damage. Key Functions 1. Overload protection- Protects electrical equipment from damage due to excessive current. 2. Current monitoring- Monitors current levels in the circuit. 3. Trip signal-Sends a trip signal to disconnect the circuit in case of overload. Applications   1. Motor protection- Protects motors from overload and overheating. 2. Power distribution- Used in power distribution systems to protect equipment. 3. Industrial control- Used in industrial control systems to protect machinery. Benefits 1. Equipment protection- Prevents damage to electrical equipment. 2. Reduced downtime- Minimizes downtime by detecting faults early. 3. Improved safety- Enhances safety by preventing electrical fires and accidents.
