Abstract

A protection system for an electrical device may include at least one temperature sensitive element located in a region adjacent to a component of the electrical device and configured to provide an output related to an actual temperature in the region. The system may also include a controller configured to determine the actual temperature in the region based on the output of the at least one temperature sensitive element and to determine a predicted temperature of the component based on the actual temperature in the region and on a predetermined heat dissipation characteristic of the electrical device.
