多功能电力参数测试仪

Parameter Test Instrument of Multi-function Electronics Power

介绍了一种基于89C52单片机电力参数测试系统的组成和检测原理。系统利用双保持器解决了电压电流的同步测量。利用倍频锁相环路防止了被测信号的失真。同时解决了无法进行在线测试的难题,使得低压供电系统对电力的分配与调度更加合理,更加快捷。

This paper provides a new approach for the composing and testing principle about a type of digital electric power parameter testing system based on SCM89c52, It can measure voltage and current using the diploid hold unit, prevent the distortion about the measuredsignal from using limes frequency lock direction ring at the same time. k can also resolve the problems that can not be rneasured on the line. This can made it distributed and adjusted for the electric power more reasonable and instant.
