Profitability of Condition Monitoring in the Electric Distribution Grid

• The deployment of sensors enables the development of condition-based maintenance, as opposed to the traditional time-based and corrective maintenance. This work explores the conditions under which the use of sensors to improve maintenance scheduling on overhead lines is economically profitable. We propose a novel methodology that converts sensor measurements into an asset condition assessment, and then into a maintenance decision. The cost of predictive maintenance is then compared to the cost of corrective maintenance over several decades, ultimately allowing to evaluate the profitability of investing into sensors. This work enables to identify the parameter values that result in profitable investments in sensors. The results show that the use of sensors is particularly justified for short-lived assets, supplying many clients.
