Detection And Protection Of Power Phase Loss And Neutral Failure
Abstract: A protection circuit provides a control voltage to a 3 -phase contactor, where the three phases of the 3 -phase power supply are inputs to the 3 -phase contactor. The protection circuit includes: four input terminals, configured to be connected respectively to the three phases and to the neutral line of the 3 -phase power supply; an output terminal, providing the control voltage to a control line of the 3 -phase contactor; and control circuitry configured to provide the control voltage when any one or more of the three phases are live and when the neutral line is connected, and to provide no control voltage when all three phases are disconnected or when the neutral line is disconnected.
