FIELD: electricity.
SUBSTANCE: according to the method since the moment of loss of voltage, operating current and non-availability of short-circuiting current in the line of main power supply source hold-up time-keeping is started for switching on of ATS network breaker; at that when this time is over in the line of main power supply source increase of operating current is tested and when at the moment of time-keeping ending operating current is increased to value equal to value of lost operating current in the line of main power supply source then summary is made about spurious tripping of the main and sectionalising circuit breakers and switching on of ATS network breaker.
EFFECT: broader functional capabilities.
