摘要
提出了一种用单片机测量电机功率的新方法，即只需检测一组线电压、一个线电流，就可得到电机的总功率．与两瓦表法相比，节省了一个电压互感器和一个电流互感器。
A singal chip microprocessor is used to measure motor power. This way can be used to measure the gross power with measuring one line current and one line to line voltage. So only one current transformation and one voltage transformation are required. This method is more simple in hardware and software than two wattmeter method.
