摘　　要：文中提出了一个在大面积集中使用电子节能灯时值得注意的中线电流太大的问题,通过对三相四线制中线电流的数值及波形的测试,分析了电流大的原因及由此可引发的几种危害,提出了选择中线的原则。This papar puts forward a question that current in middle wire is too large when electronic lamps saving energy are used on a large scale. This paper also analyzes the cause of large current and several harms caused by it,and puts forward the principle of choosing middle wire by testing the value and waveform of current in middle wire of three- phase four-wire system.
