FIELD: electric instrument engineering. ^ SUBSTANCE: meter has phase wire current-to-voltage converter, phase wire power-to-frequency converter, zero wire power-to-frequency converter, indication unit and power source. Two magnetically-connected LC circuits are used for galvanic decoupling voltage and current circuits of meter. ^ EFFECT: reduced phase error of meter; reduced self-consumption of meter. ^ 2 cl, 1 dwg |
