FIELD: power engineering. SUBSTANCE: installation has two coincidence units 8 and 11, shift shaper 9, and shift register 10; tap detectors 7 are connected to first inputs of first coincidence unit 8 whose outputs are connected to inputs of shift shaper 9 connected to shift register 10 whose outputs are connected to second inputs of first coincidence unit 8 and to first inputs of second coincidence unit 11 whose second inputs are connected to ice detectors 13 and whose outputs are connected to switching unit 12. EFFECT: improved design. 3 dwg
