FIELD: devices for inspecting state of insulation of underground pipelines. ^ SUBSTANCE: pipeline insulation condition remote control system has cathode protection station, current detector, anode, signal converting unit, copper-sulfate comparison electrode mounted in ground. Output of signal conversion unit is connected with input of modulator which has output connected with input of transmitter. Output terminals of transmitter are connected with winding of transmitting aerial. Communication channel is made in form pipeline. Operator's desk equipment has receiving aerial which has winding connected with input of receiver. Receiver has decoder. Output of operator's desk receiving equipment is connected with computer. Windings of transmitting and receiving aerials are disposed in dielectric flat-shaped frames. Any frame is made in form of tabs disposed along radius with spaces. Any winding is made of isolated wire in form of spiral. ^ EFFECT: widened operational capabilities. ^ 2 dwg |
