Critical security systems for energy supply depends upon energy storage by batteries or the cable supply. "What if this self-sufficient must be supplied?" The main focus of the paper lies on construction and adaptation of an impulse coupling which generates a sufficient voltage to supply to a monitoring system by using rotational energy at lower rotational speed and thus making a system self-sufficient energy supply system. Another main focus lies in the optimization of the failure rate in a system because of mechanical components. In this research project the theoretical approaches are checked by a suitable parameter frame in a real system. A fault tree analysis (FTA) was pulled up for the evaluation of the failure rate, to show potential failures and to validate these, we carried out other simulations by means of the Finite elements method (FEM)
