摘要
FIELD: instruments for accounting operations of alternating-current electric motors. SUBSTANCE: device has at least one voltage detector, which first and second input terminals are connected to corresponding power supply circuits of electric drive; while first and second output terminals are connected to corresponding terminals of voltage winding of power recorder. In addition device has idle time compensator, which is designed as at least one voltage transformer, which first and second terminals of primary winding are connected to corresponding power supply circuits of electric drive, secondary winding is connected in parallel opposing to output winding of current detector. EFFECT: possibility to subtract power of idle operations from total power consumed by drive. 1 dwg
