Non-contacting Voltage Presence Detection by Electric Filed Measurement on Tower Post of Transmission Line

Abstract

A feasibility study for development of a non-contacting voltage presence detector was performed. This detector is intended to be used for maintenance of the overhead transmission lines. A detection method by measurement of electric field on the surface of the tower post was proposed and investigated by means of electric field measurements at the transmission test line and numerical calculations. The results showed good performance to realize the non-contacting voltage presence detection.
