单相有功电能表设计

Single phase Available Power Watt hour Meter Design

本文介绍了一种全电子固态单相有功电能表的设计，通过对电压有效值测量，实现对电能的测量方法和电路。数据处理采用美国ＴＩ公司生产的仪表专用单片机ＭＳＰ４３０。

This paper intends to describe a available power watt hour meter by means of RMS value measure with high accurarcy,low power consuming and a simple interface to a microcontroller.
