摘要
推导了在非正弦电路中,电动系功率表的读数与单相负载的有功功率的关系.指出在正弦交流电路中无原理性测量误差,当它在非正弦电路中,用于测量负载的有功功率时,它的读数就是非正弦电路中单相负载的有功功率.
The relationship between wattmeter reading and the active powers absorbed by single\|load in non\|sinusoidal circuit has been derived. And it is concluded that the reading of wattmeter in which there is no principal error or little principal error under sinusoidal circuit is the active power absorbed by single\|load in non\|sinusoidal circuit.
