Note:
The specific objectives of this project include: (1) Developing “theoretical”-based Multiphysics models to understand phenomena behind i) internal partial discharges (PD) in solid dielectrics, and ii) electrical breakdown in air, under fast, repetitive voltage pulses in low pressure and harsh environments (-60°C - +250°C, and 0-100% humidity; Note: the harsh condition part will be optional research if the resources are available); (2) Carrying out experimental investigations to characterize the influence of the factors in i) and ii) above and validate the models and theories developed in (1); (3) Conducting experimental investigations to identify the critical frequency for (a) various solid dielectrics with gas-filled cavities and (b) various electrode geometries in air; and (4) Developing a Multiphysics theory capable of quantitatively modeling PDs and air breakdown over a wideband frequency to theoretically determine the critical frequency for insulating materials and compare it to the experimental data provided in 3).
