常に受信出来なくなる欠点を有している。That is, the transmission signal from the transmission fil leaks to the primary winding PK of the power relay transformer TO, and the power line (connected to the power receiving terminals p1 and p2) that supplies power from the power company etc. It becomes a noise signal and has a negative impact on other power equipment. Therefore, the output level of the signal sent out from the transmitter 1 is suppressed to a small level so that the leakage output level due to the signal sent out from the transmitter 1 at the primary side winding IP of the enemy relay transformer To is within the state. are doing. However, if the transmission path between the transmitter 1 and the receiver 2 becomes long, that is, the resistance value of the transmission path is large, and the output level of the signal sent from the transmitter 1 is too low, the This has the disadvantage that the receiver 2 cannot normally receive the signal sent from the transmitter 1.

出信号が上記受信機２で正常に受信出来る。Therefore, by setting the values of capacitors CO and C2 so that the signals sent from transmitter 1 are applied to the two ungrounded wires 5 and 6 in the same phase and with equal current values, the '1 power relay Since the directions of the currents flowing through the two windings of the secondary winding MS of the power relay transformer To are opposite, a voltage is induced in the primary winding P of the power relay transformer TO by the signal from the transmitter 1. Not done. That is, the transmission signal from the transmitter 1 does not leak to the primary winding P of the power relay transformer TO. Therefore, since the output level of the output signal 18 of the transmitter 1 can be set arbitrarily, the r%j of the above transmission +J, 1 and the receiver 2
Even when the transmission path becomes long, that is, when the resistance value of the transmission path is large, the transmission signal from the transmitter 1 can be transmitted to the receiver 2 by setting the M output level high. can be received normally.
