Energy harvesting technology for AC overhead insulated transmission line based on electric field induction
To solve the problem of the energy harvesting (EEH) effect of the condition monitoring devices power supply on the transmission line is not ideal. The authors designed three kinds of EEH schemes based on AC electric field induction, which can effectively improve the output power of load power supply. The EEH principle of each scheme was analysed in detail, and the influence factors such as the shape of outer energy harvester, capacitance compensation and impedance matching characteristics were analysed. Finally, the experiment showed that 140.9 mW of power was obtained in direct-mode field EEH when the line voltage level was 10 kV. The high-potential field EEH mode obtained 4.1 mW of power. The harvesting effect of the inner energy harvester with the same potential as the aluminium wire was obviously better, and 30.7 mW of power was obtained. Finally, based on the third mode, when the load resistance was 2200 Ω, the rectifier received 23.7 mW DC output. The experimental results are in agreement with the theoretical analysis, which verifies the effectiveness of the electric field induction power supply technology.
