Abstract The methods for maintaining and monitoring the condition of power system have changed significantly with advancement modern communication information technology. A strong foundation use digital twin technology data science in diagnosis switchgear health status is provided by efficient collection enormous, high-dimensional equipment operation data. This research proposes a technology-ba...

Abstract In order to clarify the distribution law of radiation optical field gas insulated switchgear disconnector defect and determine detection range partial discharge sensor, model based on uniform geometrical theory diffraction is established ray tracing method, light calculated when occurs at key positions such as basin insulator, shield, support insulator barrel. Based maximum irradiance,...

Breaking electric contact has been made for closing the circuits, respectively for taking over the temporary current conduction or for the long time conduction also for re-opening the closed electric circuit, putting out the current in this way. Although the contacts are the small parts of equipment volume in which they were mounted, there are complex exigencies and obviously different from cas...

Discussing the state of the art of current limitation in medium voltage range shows the limits and drawbacks of today's current limiting techniques. Focusing on up-to-date research projects in the field, the major part of this paper explains various kinds of current limitation by means of super conducting materials. The two major principles, resistive and inductive limiters, are introduced as w...
