A three-phase identification method and device for live detection of arc extinguishing performance of circuit breaker are proposed. In this paper, a sensor with three antennas is used to detect the electromagnetic wave radiated by the circuit breaker, and the three-phase identification is realized by controlling the receiving angle of the antenna and comparing the amplitude of the received electromagnetic wave. The method proposed in this paper has the technical advantages of simple implementation and low cost of detection device, and can realize the three-phase identification of live detection of circuit breaker arc extinguishing performance.
