METHOD OF CONTROLLING ELECTRIC POWER CONSUMERS VIA POWER MAINS

摘要

FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering for remote control of remote from each other electric power consumers by transmitting control commands via the power mains with the voltage of up to 1,000 V.EFFECT: technical result is ensuring both alternate and combined control of multiple consumers; according to the method included at the inlet of the four-wire power transmission line to the break of the zero wire is a source of variable in value and (or) in phase EMF, and at the line outlet by the change of phase voltages given are commands for controlling electric power consumers.1 cl, 4 dwg
