摘要
阐述了不同三相电路所应采取的有效测量方法,总结了一瓦特表法、二瓦特表法、三瓦特表法各自的适用范围及三相电路功率测量的接线特点。在分析了功率表读数在不同接线方式下的物理意义的基础上,论证了一般条件下三相功率的实际测量方法与符合定义的测量法之间的等价性。
This paper formulates effective measurement methods in the light of different three-phase circuit.And the applicability of the one-wattmeter method,the two-wattmeter methods and the three-wattmeter method are summarized.The connection traits of three-phase power measurement are summarized too.It demonstrates that the actual methods of measurement of three-phase power coincides with the methods of measurement to accord with definition under generic conditions on the basis of having analyzed the meaning of wattmeter reading in the different power measurement techniques.
