  • Method and apparatus for monitoring poly-phase currents in poly-phase equipment
    Patent number: 4241336
    Abstract: A method of and a device for monitoring poly-phase currents in poly-phase equipment, in which a phase signal representative of the current in each phase of the equipment is obtained, the phase signals multiplexed so as to obtain a single multiplexed signal, and the multiplexed signal then processed to extract from it an output signal or signals representative of, for example, overload, unbalance, earth fault or short circuit conditions.
