Abstract
In order to strengthen the safety protection of the construction of the adjacent charged object and ensure the safety of the construction. Based on the MEMS electric field sensor technology, the MEMS electric field monitoring and alarm device is developed for the two different electric field conditions of DC and AC. The device has wireless transmission, GPS/Beidou Positioning and other functions. It can realize real-time local alarm, remote server monitoring based on GPRS signal transmission, mobile APP online monitoring and so on. Both DC and AC power frequency electric fields are measured in a large range of range of 0~1000kV/m, the resolution is 20V/m, and the total uncertainty is within 2%. In the Changji-Guquan and other transmission line projects, the functions are well tested and the results are accurate.
