FIELD: electricity.
SUBSTANCE: method to connect three-phase electric circuits includes connection of at least one three-phase source of energy and at least one load connected as star with a zero wire, at the same time the common point of the load star is connected to the common point of the energy source star by serially connected active resistance Ro and inductance Lo.
EFFECT: expansion of functional capabilities, reduction of current in a zero wire down to zero, provision of sinusoidal shape of current in the zero wire, transition of capacity spent in the zero wire into load of energy-saving lamps.
