Summary on Grant Application Form |
|
A pre-requisite for achieving an improved reliability and linearity in many vacuum-insulated electrical devices and systems is a much enhanced performance of the associated high voltage solid insulating structures. To achieve this objective, an investigation is proposed to advance the understanding of the mechanisms responsible for the surface flashover phenomenon that ultimately limits performance. Pulsed field techniques would be used to study the electrical evolution of the discharge process, whilst synchronised fast optical photographic and spectroscopic techniques would record its complementary optical signature.A parallel technical strand draws upon these findings to evolve an optimum insulator design specification based on surface processing, external geometry, triple junction profile and conditioning procedures. The performance of such re-engineered insulating structures would be evaluated under operational device conditions.
