Whether in domestic, industrial or even power plants, phase relays are key elements to maintain the stability and order of the three-phase voltage that supplies machinery, motors or turbines. From the classic phase failure relay, without any adjustment, to the sophisticated digital relay capable of evaluating the state of each phase and acting according to what the user decides, seeing the state of the three-phase line on a screen, all form part of a wide range of controllers.
