GENERATOR FOR INJECTING CURRENT SIGNALS INTO THREE-PHASED LOW 380V VOLTAGE LINE AT 50 Hz FREQUENCY

摘要

FIELD: electric engineering, possible use during organization of communication channels using three-phased electric supply lines at 380V without processing by high frequency rejecters. ^ SUBSTANCE: invention is realized due to optimal selection of working frequency range with consideration of lengths of 380V lines, and also consideration of absence of harmonic interferences of 50 Hz frequency in selected frequency range. ^ EFFECT: 100 times increased transfer speed of current signals. ^ 1 dwg
