INDUCTION ELECTRICITY METER Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: electricity meter has rotating magnetic system with cores of current and voltage circuits. Cores are separated by gap in which counterpole is positioned. Magnitude of gap between cores of current and voltage circuits exceeds value of gap between voltage circuit core and counter pole. Cores of current and voltage circuits are positioned on upper plane of carrying bracket. Counting mechanism has reduction gear with reduction coefficient of the first worm-to-worm gear equals to 1: 60 and the second pair of gears is equal to 1:10. EFFECT: improved loading characteristic of meter; simplified regulation. 4 cl, 8 dwg
