Zusammenfassung:FIELD: electric engineering. ^ SUBSTANCE: invention may be used when setting up communication channels with usage of three-phased electric networks (0,4-35)kV without processing thereof with high frequency rejecters. ^ EFFECT: increased generator efficiency, during generator operation "parasitic" current at frequencies f0±300Hz and f0±600Hz do not appear and energy of generator used for creating signal currents is not spent on generation of these currents, eliminated excess voltages between key contacts. ^ 1 dwg
