HV pulse measuring device on output of pasture fence has contactless sensor for acquiring electrical field strength at close distance from HV line

摘要

A contactless sensor (17) is used for acquiring an electrical field strength at a close distance from a high voltage line (14). The material of a PCB forms a dielectric layer (19) between laminations (20,21). The HV side the lamination (21) is connected with a ground potential while the HV side lamination (20) feeds the measurement signal of an evaluation unit and indicating element (33) across the measurement line (22).
