Year: 2025

Type: article

Abstract: The article presents the results of studies of a voltage sensor based on a system of galvanically coupled bodies. The necessity of taking into account the sources of external electric fields when determining the equivalent capacitance of the passive body included in the sensor is shown. The results of a study using computer simulation by the finite element method of the influence of the fields of the active body on the equivalent capacitance of the passive body, as well as the influence of the electric fields of neighboring phases on it, are presented. When studying the influence of the electric field of an active body, the change in distance both from the active body to the measuring resistor and from the measuring resistor to the passive body was considered. The last section of the article presents the results of experimental studies of the influence of the electric field of an active body on the equivalent capacitance of a passive body, which confirmed the results of computer modeling.
