摘要
利用瓦秒法检查电能计量装置的接线是用电检查日常工作。在相关的计量规程里,对瓦秒法的规定过于原则,可操作性并非最佳,通过变换其公式,对功率因数提供几种测量途径,摸索到瓦秒法“快、准”的实践方法,文章还通过实例进行了验证。
Examination of connecting lines for electric energy metering devices used W-second method is daily work of power supply inspection. Within pertinent metering regulations, operability are excessively not the optimum to W-second method regulation. Quick and accurate method is obtained through formula transferring and several ways to get suitable power factor are given. Finally the method is verified with practical examples.
