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...

Characterization of a new method for partial discharges measurements in HVDC GIS

Detection of partial discharge (PD) in any high voltage equipment is of great importance to improve the reliability of the device and the power system. Characteristics of PDs, such as: rate of occurrence, magnitude, location and the type; gives information of the assets that must be considered. Nowadays, there are many different methods for...
