This paper expounds the working principle of non-contact voltage detector and the electric field sensor which made by the technology of microelectromechanical systems (MEMS), determined the requirements of the detecting area and the threshold of the detector through simulation, and correct the threshold by carrying out experiments, which shows that by setting the threshold of the detector at 25kV/m, when the detector is 10-15m away from the conductors, or 2m away from the tower toward the conductor at the tower body whereas the same high as the conductor or on the crossarm, the detector can effectively identify whether the conductor is power on or off. The MEMS no-contact voltage detector and the method put forward by this paper can solve the problem of voltage detecting on UHV transmission lines, which has wide popularization and application value.
