Construction of Novel Online Partial Discharge Monitoring System using Power Line Communication

Abstract

A lower-cost and higher sensitive partial discharge (PD) detection method is required, but it has not been established yet. This article presents a novel online PD monitoring system using power line communication (PLC) with ferrite core (FC) as a PD sensor. Combining PLC and ferrite core is expected to allow us to develop a low cost and highly sensitive continuous monitoring technique. This paper presents a concept of PD detection by PLC, constructed test circuit and experimental verification.
