摘要
介绍三相三线智能电表的计量原理,分析正确接线时出现负电流的原因并用实例进行验证,最后给出在线判断轻载用户无功补偿过量或不足的方法。
The measurement principle of the three-phase and three-wire smart meter was introduced.The reason of the negative current under the correct wiring condition was analyzed and verified by examples.Finally,an online method for judging the over-or under-reactive compensation of light load users was given.
