Relay coordination ensures that protective relays in an electrical system operate in a prescribed sequence to isolate faults with minimal disruption to the rest of the system. It is crucial for maintaining system stability and preventing equipment damage by ensuring that the closest relay to a fault activates first, followed by others if necessary.

Relay operation involves using electromagnetic devices to control the opening and closing of electrical circuits, allowing automated switching and protection for electrical systems. This process is critical for ensuring reliability and safety in a wide range of applications from household appliances to large-scale industrial equipment.

Relay Operation

Fault isolation is the process of identifying and isolating a fault within a system to prevent it from affecting the overall operation. It is a critical component of diagnostics and maintenance strategies, ensuring that systems remain reliable and efficient by quickly pinpointing issues for resolution.
