对于数字式功率表将出现负读数。测量三相对称负载的无功功率在三相对称系统中，三相电压完全对称，各相负载阻抗完全相同，则各相电流亦完全对称，此时仅需要用功率表测量出一相负载的有功功率P，再乘以3倍，则得三相总功率，即P=3Pφ=3×Uφ×Iφ×cosφ无功功率的测量为了测得三相无功功率，可按接线，将功率表的电流线圈串入任意一相线路中，而将电压线圈电路连接到另外两相的电源端上，由于三相电路中任意两相间的线电压总是与星形联接时的第三相相电压相位差90°。

如何预防电气火灾？完善短路保护和过载保护，安装断路器和漏电保护器。线路敷设规范，连接可靠，线径符合使用要求。用电设备完好，设备与电源连接可靠，不超载使用电气设备。安装使用合格的电气元件和设备。定期检查绝缘性能、电器元件功能及设备状况，特别是短路保护和过载保护的可靠性。电气火灾怎么扑灭？从灭火的角度出发，电气火灾有两个特点：一是电气设备着火或引起火灾后并未与电源断开，仍然带电；二是有些电气设备(如电力变压器、断路器、电动机起动装置等)本身充油，发生火灾时，可能喷油甚至爆炸，造成火灾蔓延，扩大火灾范围。
