PURPOSE:To enable to transmit for a long distance and to increase the reliability of signal transmission, by providing the repeater compensating the attenuation of signal in parallel with the distribution lines between stations opposing each other, in the system transmitting signal through the use of distribution lines. CONSTITUTION:Between the lines of the distribution ines 2, the circuit connecting the primary winding of the transformer 42 and the capacitor 41 in series is provided, and the secondary winding of the transformer 42 is connected to the pulse generating circuit 45 which generates pulses when the secondary winding of the transformer 42 is more than a given level through the filter circuit 43 and the gate circuit 44. Further, the thyristor 46 triggered with the output of the circuit 45, diode 48 connected in anti-parallel with the anode and cathode of the thyristor 46, and the capacitor 47 connected in series with the anode of the thyristor 46 are provided, and the repeater is constituted by connecting the other end of the capacitor 47 and the cathode of the thyristor 46 between the lines of the distribution lines 2. |
