FIELD: electricity.
SUBSTANCE: device contains terminals of network A, B, C, three voltage-check relays with group of normally closed, group of normally open and additional group of contacts, common capacitor, phase throttles and input terminals. Thus network terminals are connected to AC source, each relay is connected on phase voltage between similar phase and neutral wire. Common capacitor is connected between previous and recovered phases. Phase throttles are connected in break of corresponding phases between network terminals and input terminals. And throttle of recovered phase is bridged. Throttles of composite phases are used for additional turn of adjacent phase voltage vectors.
EFFECT: device downsizing and weight reduction.
