Abstract: Insulation systems that present an electrical stress grading through the disposition of resistively graded networks between insulating layers is described. The resistively graded networks may be implemented by coating insulating material with resistive material, and wrapping the insulation material around a conductor. The resistive material may be linear or non-linear material. Fabrication of the insulating material, the resistive material, and the coating process are also discussed, as well as the application of the insulation to the conductor are also discussed.

Abstract: An electrical machine of a vehicle electrical propulsion system includes a stator, a rotor, and a stator winding all disposed within a housing thereof. The stator defines a central bore elongated along a longitudinal axis, and multiple slots circumferentially disposed around the central bore. The rotor is held within the central bore and rotates relative to the stator. The stator winding includes a core conductor, an insulation layer surrounding the core conductor, and a conductive shield layer surrounding the insulation layer. The stator winding extends through the slots of the stator. The stator winding includes an in-slot portion within the slots of the stator and an end-winding portion outside of the slots. The conductive shield layer surrounds the insulation layer along both the in-slot portion and the end-winding portion of the stator winding.

Abstract: Aspects of the present disclosure are directed to systems and methods for detecting Partial Discharge (PD) associated with wide bandgap semiconductor-based electrical drive systems in real time. In one aspect, signals, including noise associated with drive switching and other background noises are detected using a sensing device. The signals are received by a real-time spectrum analyzer. The spectrum analyzer transforms the signals into the frequency domain and determines or registers the frequency domain profiles of the signals. The spectrum analyzer performs signal discrimination between at least one other signal included within the signals and switching noise based on their frequency domain profiles. Based on the discrimination analysis, the presence of a partial discharge signal may be detected. A physics-based signal discrimination approach can also be used for signal discrimination, for example utilizing pressure-dependency of characteristics of a PD signal.
