Device and method for protecting an electric machine

摘要

An aim of an embodiment of the invention is to better use the time forecast for switching off an overload protection device. For this purpose, the determination of a trigger-release time reserve is related to a corresponding evaluation. In such a manner, it is possible, for example to dynamically determine whether a desired process can be carried out in the total length thereof or automatically disjointed, thereby making it possible to generate corresponding warning signals.
