"Requirements and application of UHF PD Monitoring Systems for gas insulated systems and Increased operation reliability through continuous PD monitoring"
Synopsis
This tutorial explores the requirements and applications of ultra-high frequency (UHF) partial discharge (PD) monitoring systems for gas-insulated systems, as well as the enhanced operational reliability achieved through continuous PD monitoring of high-voltage assets. Based on CIGRE Technical Brochure 933, the session outlines essential hardware and software specifications, performance expectations, and strategies for reducing false alarms through advanced signal analysis and defect recognition. It also highlights real-world applications of continuous PD monitoring in power cables, transformers, and rotating machines, demonstrating how versatile, multi-channel systems can provide early detection of critical defects and support proactive asset management.

Speaker
Wojciech Koltunowicz received his M.S., PhD and DSc degrees in electrical engineering from the Warsaw University of Technology in 1980, 1985 and 2004 respectively. From 1984 to 1987, he was a research scientist in the High-Voltage Department with Institute of Power (IEn) in Poland. From 1987 to 2007, he worked at CESI in Italy, where he was mainly involved in the HV testing and diagnostics of electrical equipment. In 2007, he joined OMICRON Energy Solutions GmbH in Berlin, Germany, where he is involved with the monitoring of HV equipment and diagnostic services. He is convenor of CIGRE WG D1.66 "Requirements of PD Monitoring systems for GIS/GIL Systems" and a member of CIGRE AG D1.02 for High Voltage and High Current Test and Measuring Technique and Diagnostic and a member of AG D1.03 for Insulating Gases. He is also a member of IEC TC42 MT 14 (IEC TS 62478), and senior member of IEEE. He is the author of more than a hundred technical and scientific publications.
