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.
