Weband a set of measurements performed with a network analyzer. Both the measurements and the simulation results are shown in Fig. 3 where the agreement is apparent. Using this validated cable model, we now simulate the propagation of a pulse through a system consisting of an ideal PPS signal generator with parametrized pulse rise time The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material. Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material. The carbonized areas are more conductive than the pristine insulator, increasing current flow, resulting in increased heat generation, and eventually the insulation becomes completely condu…
