The test bench simulates the direction with respect to the relay by dictating the polarities of the voltage and the current and demonstrates the working of the directional overcurrent relay

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.
