Partial discharge measurement of transformer with ICT facilities

Abstract

Recent development in Information and Communication Technology (ICT) has drawn attention of scientists and engineers to develop ICT enabled laboratories. In this context development of an ICT enabled high voltage laboratory with facilities of remote operation is required because of its demand in the Engineering education as well as the assessment of insulation for continuous monitoring of the health of power equipment. The insulation of the power equipment is degraded due to the cumulative effect of the electrical, thermal, chemical and mechanical stress caused by the partial discharges (PD). Partial discharge detection and measurement constitute an important tool for quality assessment of insulation systems in high voltage (HV) power equipment. This paper reports on the development of ICT enabled remotely operated high voltage laboratory (ICTRHVL) for on-line measurement of partial discharges (PDs) of a model transformer. The remotely operated high voltage laboratory includes the partial discharge assessment facilities with ICT enabled technology will help the users to perform partial discharge tests and assessment on-line, in real time on real equipments, by sitting at their own place by local area network (LAN) as well as through the internet.
