FIELD: electric power engineering.
SUBSTANCE: invention relates to electric power engineering. Installation contains in each of three phases capacitors (1-3), which with one outputs are intended for connection to three-phase network A.B.C with zero wire N, and the second outputs are connected to outputs of two in-series according to connected diodes (4,5). Novelty is that to one extreme output of diode (5) is connected according to third diode (6), second output of which is intended for connection to zero wire and switch (7), second output of switch (7) is connected to common point of second output of first capacitor and output of first diode (4).
EFFECT: reduced power losses.
