Experiences from implementing a risk based maintenance strategy using an integrated network information and maintenance system

Maintenance and renewal are important parts of distribution system asset management, as means to control risk. Distribution companies are hence increasingly recognising risk assessment and risk management as important tools in this context. This paper reports on experiences from implementing a risk based maintenance strategy using a maintenance management system. The paper illustrates benefits which can be achieved through implementing a risk differentiated maintenance strategy on a company portfolio of MV/LV substations, resulting in better risk control in addition to lower overall cost for the distribution network company.
