The purpose of the talk is to give an overview of physical phenomena and challenges in electric insulation systems for airborne applications. First of all, the general context will be remembered. The embedded electric power is expected to significantly increase in future aircrafts. In order to manage this increase, while limiting the mass and volume of electric conductors, there is a need to increase the voltage. However, the transition to higher voltages in airborne applications is a real challenge.
In this lecture, concrete examples will be presented. Examples of questions, which will be discussed during the presentation, are: how to design a partial-discharge-free cable? How to test a complex equipment, like a converter, with respect to partial discharges? How to determine creepage distances at high altitude? Is there a need to take the space charge phenomenon into account in sizing of the electric insulation system, or can it be neglected? What is the aging effect on dielectric performances, and how to demonstrate that no electrical insulation failure will occur for a 30 years' application?
We will try to bring - at least partially - answers to these questions, to share our vision on how to manage the electrical insulation and to give perspectives in order to design a safe and reliable insulation system for airborne applications.
