FIELD: electricity.
SUBSTANCE: substation transformer start-up method, at which, first, two input terminals are connected to two phases of a three-phase network at transition of phase voltage of the third phase of the network through zero, and then, the third input terminal is connected to the third phase of the network at transition of linear voltage from two previous phases through zero.
EFFECT: simpler implementation of the method and elimination of additional losses in a three-phase transformer owing to providing accuracy of initial moment of actuation of two phases.
