FIELD: power engineering.
SUBSTANCE: device contains transmission control block, made in form of high frequency generator, and receipt control block, connected to automatic remote control station being monitored. These blocks are interconnected through connection filters and communication capacitors by phase wire, which is used as spatially distributed sensor and to which measuring blocks are connected, which are in turn connected to signalers of limitary ice load. At input of transmission control block, prediction block is mounted, using meteorological sensor parameters as original signal, on basis of which durations of discrete high frequency signals are formed at input of transmission control block, with their amplitude being continuously modulated further by ice coatings, spatially distributed sensor and discrete measuring blocks. On basis of parameters of beginning of ice coating formation and limitary ice coating load, quantitative values of ice coating formation process and emergency ice coating load growth process are determined. Corresponding signals are received at dispatching station.
EFFECT: creation of a new system for controlling and predicting extreme ice coating situations, working only during influence of real ice and wind events on power lines, consuming no power on controlled supports, using triple modulation of high frequency oscillations for efficient usage on all power lines with high degree of diagnosing.
