FIELD: electricity.
SUBSTANCE: invention relates to power supply systems and control over telemechanics of long metal communications. Disclosed is a method which consists in arrangement of autonomous power supply of telemechanics devices, communication and monitoring of plant health due to collection and conversion of guidance currents directly from their receiver, i.e. communication. At the same time the low-voltage power supply device selects only the positive polarity of low voltage, which is harmful for communication. Guiding currents from the receiver are converted into electric power for power supply of telemechanics, communication and the proposed in the invention method of continuous monitoring of serviceability of drainage protection.
EFFECT: providing quality and continuity of electrochemical protection of metal communications, avoiding the need for repair and replacement of telemechanics and communication elements.
