基于ADE7758掌上型电流互感器现场测试仪的设计与实现

Designing On-the-spot Detector for the ADE7758 Inductive Palmtop

在高压供电低压侧计量(简称高供低计)的电能计量装置中,低压电流互感器(CT)是重要的计量设备。计量装置的整体误差就是由互感器的误差和电能表的误差构成的,因此对电流互感器的现场测试就十分必要。由多相数字电能表芯片ADE7758和单片机(MCU)78E58构成的低压电流互感器现场测试仪,可以检测互感器的比差、角差。

It is important to test the precision of the current sensor in the device of computation for power supply. The paper mainly discusses the design of testing on - the - spot current sensor based on ADE7758 and 78e58, and it can detect comparative error, angle error of current sensor.
