Evaluation of the Caoping electric field observation system in Lixian County, Gansu Province

In this paper, we briefly conducted an observation overview of the Caoping electric field in Lixian County, collected observation data for graphical analysis, and compared and measured the parameters of observation quality (correlation coefficient and difference). The conclusions of the study follow: The newly established observation system operates well and produces high-quality data internally; Two observation systems can observe simultaneously without interfering with each other and can receive external abnormal information, such as geomagnetic storms; The solid non-polarized electrode selected for the main observation system better correlation. This article serves as a reference for electrode layout and electrode selection in the observation of ground electric fields at other stations.
