Biography

Diagnostics, Maintenance and Replacement Strategies Applied to Insulators & Cable Systems

Dr. Ross is Director at the Institute for Science & Development, Ede and Professor at HAN University of Applied Sciences. He is also Asset Management Research Strategist for the transmission grid operator in the Netherlands and parts of Germany. He worked in the past at KEMA in the area of reliability and post-failure forensic investigation and his present fields of specialization include reliability statistics, electro-technical materials, sustainable technology and superconductivity. He is author of ‘Reliability Analysis for Asset Management of Electric Power Grids’ based on his extensive experience with power utilities.

The term ‘Smart’ is related to the fourth industrial revolution, dubbed Industry 4.0. Reliability 4.0 concerns ‘smart’ production or systems that incorporate four key themes: interconnection, information transparency, technical assistance (e.g. using sensors) and decentralized decisions. This presentation discusses the background of maintenance activities and styles with focus on power cables and associated insulators. First, the 4.0 wave is compared to preceding waves. Next, basic maintenance strategies are explained in terms of hazard rate. Finally, maintenance activities including inspection, servicing and replacement are discussed for the three main styles, i.e. corrective, period-based and condition-based maintenance.
