Abstract:

For Rogowski coil, as the current carrier passes through the coil center, it fails to locate the lightning current. With the aim of measuring and locating the lightning current at the same time, this paper developed a lightning current sensor. In this paper, the physical model, geometric parameters, and manufacturing process of the lightning current sensor were introduced, and then a novel sensor coil was developed. To verify the reliability of the sensor, experiments were also performed. The good response characteristics of the sensor were also demonstrated. Last but not least, the sensitivity of the sensor was calibrated, and the formula was determined, which demonstrated sensor output voltage and derived by current and distance, providing theoretical and experimental evidence for practical application.
