Abstract

FIELD: electrical engineering. SUBSTANCE: device has converting unit 2 whose output is connected to recording unit 3 made in the form of microcomputer, three-phase inverter 4, and current sensor 5 built up of parallel-connected resistors and connected through its output to one of inputs of three-phase inverter 4 and to input of converting unit 2; other input of three-phase inverter 4 is connected to terminal meant connection to check-up circuit; inverter output is connected to terminals for three-phase power plant. EFFECT: improved validity of information; improved design. 2 dwg
