Demonstration Unit for Time Delay Relay Directional Over Current Relay

This is a demonstration panel to show the working of “DIRECTIONAL OVER CURRENT RELAY”. A protective relay is a device designed to trip a circuit breaker when a fault is detected.

A directional relay uses an additional polarizing source of voltage or current to determine the direction of a fault. The fault can be located upstream or downstream of the relay's location, allowing appropriate protective devices to be operated inside or outside of the zone of protection.
