Research on Energy Acquisition Method Based on Ceramic Capacitor Insulator

A method for encapsulating the ceramic capacitors inside the insulator and performing on-line energy extraction by the principle of capacitive voltage divider is proposed. Through the field test, the ceramic capacitor insulator with a score of 4nF/80nF can obtain a maximum output power of 2W, which verifies the feasibility of the method. By constructing a 10kV circuit simulation platform, it is found that when the secondary side of the isolation transformer series inductance or the two isolation transformers are connected in series, the output power is increased compared with the single isolation transformer, and the output power of the secondary side of the isolation transformer series inductance is higher.
