This dataset was generated through field experiments conducted by KT-400SZ (Shenzhen Ketan Electronic Technology Co., Ltd.), which consists of a natural electric field detector, a dedicated detection cable, a dedicated signal probe, a USB data cable, and host software. The host and probe are connected by a detection cable, with the host connected to two positive and negative electrodes. By inserting positive and negative electrodes on the surface to receive the electrical components of the geomagnetic field on the surface, the measured information contains both dynamic and static information of the natural electric field.
