FIELD: power plants. SUBSTANCE: transducers, which are located in points for checking ice load on wire and rope, convert signals from outputs of ice load detectors into respective voltage of direct current of same or opposite polarity. Periodic switches of power supply of transducers in points of ice load detectors and presence of commutator of channels in receiving station provides transmission of output voltage of transducers through rope-earth transmission channel into inputs of respective receivers which monitor ice load of phase wires and lightning-protection rope. EFFECT: increased functional capabilities due to simultaneous monitoring of ice load of wire and lightning-protection rope in order to control equipment for thawing ice on wires and rope. 3 dwg
