In power system, electronic current sensor instead of electro-magnetic current transformer is the intending trend. Thus the principle of electronic current sensor applied in plug and switch system is introduced firstly, and then the configuration characteristics such as the influence of temperature, the multi-layer and asymmetric winding of coil, the location of current source, etc. are analyzed. At last, the collective influence of many factors is considered. The analysis result will provide the guidance for the performance improvement of electronic current sensor.
