FIELD: electricity.
SUBSTANCE: when a three-phase symmetrical system of phase voltage becomes unsymmetrical and at any time interval two phase voltage absolute values become equal to each other and a half of the linear value and the third value is by one and a half time more than the phase value, then a conclusion is made about a break in the linear and neutral wires.
EFFECT: enlarging functional capabilities of the method.
