Abstract

PURPOSE:To make it possible to detect securely phase absence of a power supply, a fault of a diode, etc., by providing the 1st to the 4th signal AC power supplies, etc., and then by providing a transmitter with a selection switch unit and a receiver with an abnormality detection circuit respectively. CONSTITUTION:Alternate positive and negative signal waveform voltages selected by the selection switch unit of a transmitter are extracted corresponding to the output of a high-frequency oscillator and then transmitted as conversion signal waveform voltages, so that even positive and negative signal waveform voltages in the same phase can simultaneously be transmitted via the same transmission line. Further, a receiver is provided with an abnormality detection circuit and when the time width of each transmitted signal waveform voltage and each signal waveform voltage from a diode rectifying circuit exceeds a prescribed value, an abnormality detection relay is put into operation. Therefore, the fault of the diode of a diode matrix circuit of the transmitter or receiver and the phase absence of the 1st to the 4th signal AC power supplies can securely be detected.
