The study seeks to determine the real time in electrical power system, which consists of generating, transmitting and distributing equipment by using redistributing active power of electrical generators in order to organizing the overload operation of electrical power transmission line loading in such case that the spare loads of electrical station are not covering the important and necessary loads at failures. The most of laws related to electrical power systems design indicated to proper ratio of real time of electrical power system equipment along with characteristics of probability distributed functions in addition to statistics methods which give a high possibility to reduce the real time of considered loads; so; this leads to the requested solutions which reduce the damage of failures at any time.
