Setup and preliminary results of an online thermal condition monitoring system for MV cable joints

摘要

Collaboration with the Electricity Authority of Cyprus (EAC) and the University of Cyprus (UCY) has allowed development of an experiment in a distribution substation. Temperature condition monitoring units were installed on selected underground cable joints within MV sub-station in Cyprus. Real-time current loading data, weather conditions as well as surface temperature by the cable joints are used for the development of the thermal prognostic models. This paper introduces a novel thermal condition monitoring system and presents the first preliminary results.
