Abstract
A surge current delay time period is added to a current limit delay time period in order to permit a longer time for a possibly temporary larger-than-steady-state electrical current, such as for a start-up power requirement. A system is described for permitting a legitimate surge current by distinguishing true over-current fault conditions from temporary surges in terms of high current duration time.
