| Abstract: | 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. |
