【摘要】 对称三相三线制电路有功功率和无功功率的测量是电气工程中的主要工作之一.系统研究、总结了通过使用一只瓦特表测量得出三相负载的总有功功率和无功功率的思路,并给出接线电路图。这给对称三相三线制电路的功率测量提供了既简单又易操作的新方法,具有的实用意义.更多还原

【Abstract】 In electrical Engineering,it is one of the major work that measure the average power and reactive power on symmetric three-phase three-wire circuit.This paper advances the idea of measuring power of three-phase load,by using one Wattmeter,and draws circuit.It is both simple and easy the new method of the measuring power on symmetric three-phase three-wire circuit,and has practical significance.更多还原
