FIELD: power engineering; recording ice on conductors of high-voltage power transmission lines. SUBSTANCE: icing indicator has transmitting device, case in the form of sleeve made of heat- conducting diamagnetic material and fitted onto line conductor, n ferromagnetic clip-shaped plates fixed on case at design distance from each other for turning through 360 deg./n, microphones, power supply, and wires for connecting microphones and transmitting device to power supply. EFFECT: enhanced reliability, facilitated installation, wiring, and servicing of icing indicator. 1 cl, 1 dwg |
