A novel contact less over voltage Monitoring Method based on the principle of Electrostatic Coupling

A novel contact less voltage method based on the principle of Multi-conductor electrostatic coupling was presented in this paper. The actual voltages of the transmission lines can be deduced by the inductive voltage of the sensor and the transition matrix. The performances of steady state and transient state of the sensor were simulated by ATP. The experiments were done in Wuhan high voltage research institute. Results of the tests and simulations show the feasibility and availability of the presented method.
