Design method of high frequency current sensor based on neural network

The high frequency current sensor is widely used in the partial discharge detection of electric power equipment. Transmission impedance is the most important technical indicators, mainly depends on the sensor coil turns, integral resistance and core performance. In the conventional design of high frequency current sensor, the choice of coil turns, integral resistance and magnetic core performance depend on experience, and cannot be accurately designed, which is very inconvenient. In this paper, a new design method based on the BP neural network was presented.
