WebSep 21, 2024 · This benefit is of little use if the system does not detect the first fault and fix it. As a result, earth fault detection relays will monitor the phase-earth voltage on each line. (This will create a very weak star (wye) point on the system.) When an earth fault is detected on one phase then that phase is deliberately shorted to earth.
