A Power Supply Method for On-line Monitoring Instruments based on Insulation String Embedded Resonators in Domino Form

With the development of smart grid, more and more intelligent instruments are used. This paper firstly summarizes the situation of power supply for online monitoring instruments. Consideration for more reliable and continuous, we creatively promote a kind of power supply method for online monitoring instruments based on insulation string embedded domino resonance coils. The principle of domino wireless power transfer technique is introduced and the mathematical model is established. Initial experiments are conducted. The results show that this new kind of power supply method meets the demand for power supply for on-line monitoring instruments and the insulation requirements in high-voltage environment.
