Partial Discharge Recognition of Defects in Gas Insulated Systems under DC Voltage

The thesis consists of 7 chapters. The first chapter will explain the background, motivations and the general overview of the thesis. Chapter 2 is a literature review describing the physics behind the creation of PDs. The conditions necessary for the occurrence of PDs are covered in addition to an analysis of the different types of PD in GIS...

Partial Discharge Analysis in HVDC Gas Insulated Substations

Nowadays, Gas Insulated Substations (GIS) are vital nodes of the Transmission Network due to their compact dimensions permitted by the use of SF6 as insulating medium and the high reliability guaranteed. Nonetheless, the strictly requirements of safety in operation and continuous power supply catalyse the attention to improve the reliability and...
