An electric field monitoring system device

technical field

The utility model relates to an electric field monitoring system, in particular to an electric field monitoring system device for substation power facilities.

Background technique

The development of a city is inseparable from electricity. However, some citizens are "disguised by talking about electricity", and have misunderstandings about some electric facilities, worrying that it will produce electromagnetic radiation that is harmful to human health. Since "substation radiation" is invisible and intangible, no matter how the rumors are dispelled, some citizens still feel that what they hear is false and would rather believe it. At present, the conflicts between citizens and power companies around power facilities, especially substations, are often reported in the media. At the same time, after some power equipment is damaged, the electric field generated will be different from that in normal operation. The difference in electric field can be used to infer the power of power facilities. Therefore, it is more and more important to establish a system that can monitor the electric field strength of power facilities.
