Abstract
An electrical fuse maintenance system includes sensor adapted to measure the current flowing through a fuse element, the voltage on the fuse element, the temperature of the fuse element, and/or the temperature of an environment surrounding the fuse element, a controller configured to monitor the current, the voltage, the temperatures over a period of time while the fuse element is connected to an energized electrical power unit. Based on the monitored current, voltage and temperatures, the controller is adapted to estimate a service life remaining of the fuse element.
