FPA AC CURRENT TRANSDUCERS

Power transducer FP series power Transducer

Quick Overview

交流电流、电压变送器是一种能将被测交流电流、电压转换成按线性比例输出的直流电流或电压的仪器。配以相应的指示仪表或装置,可在电力系统交流电路中实现对电流、电压的测量和控制。 FPAR、FPVR与FPA、FPV、FPAX、FPVX的区别是真有效值变换,不随波形畸变而影响测量精度,因此特别适用于波形畸变严重的地区。

1.Introduction:

The AC current feeder is an instrument that converts the measured AC current into a DC current or voltage that is output in a linear ratio. With the corresponding indicator instrument or device, the measurement and control of current and voltage can be realized in the AC circuit of the power system.

The difference between FPAR and FPA is the true rms transformation, which does not affect the measurement accuracy with waveform distortion, so it is especially suitable for areas with severe waveform distortion.

  Models and specifications:

FPA: 1 unit of avg. to rms conversion

FPAX: 3 unit of avg. to rms conversion

FPAR: Ture rms conversion

FPAT:Dual output(avg. to rms conversion)
