Power Relay Protection Direction

Home / Power Relay Protection Direction

Directional relays are protective devices that isolate faults in power systems by detecting the direction of fault currents. This White Paper describes the sense, the potentials and the use of directional protection and directional zone selectivity functions, hereafter called "D" and "SdZ D" respectively.

DIRECTIONAL PROTECTION

But in modern networks with more than one power source, or in networks that have multiple lines for conveying electrical power the directional protection is essential in order to achieve selectivity.
