Online monitoring solution for transmission line lightning arrester based on electric field energy operation
Date: 2025-11-17Read: 11
1. Power supply principle
Unlike lightning arresters in substations, transmission line lightning arresters work on high-voltage transmission lines without power supply conditions, and monitoring equipment cannot work. Even if built-in batteries are installed, they can only work briefly and cannot operate for a long time. This product overcomes the shortcomings of traditional monitors by converting electric field energy into electrical energy to achieve power supply. Its power supply principle is shown in Figure 1.
2 Data Collection and Computation
We used 16 bit AD to collect the leakage current of the lightning arrester, calculated the total leakage current and various harmonic currents using FFT algorithm, and designed a circuit and program for recording the number of lightning strikes.
3 Data transmission
The monitoring device uses a 2.4G radio frequency wireless method to transmit data to the data receiving device, which then transmits the data to the data center via GPRS.
