In addition to after-laying of new-installed high voltage (HV) power cables the use of on-site non-destructive on-site testing and diagnosis of service aged power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. In this paper based on field experience an...

PD diagnostic using Oscillating Wave Test System (OWTS) is very powerful measurement and very sensitive measurement. Many parameters can influence the quality of the measurement and several problems can occur during performing PD measurement. In this study, several parameters which can influence the quality of the measurement and problems...

In this study, three artificial defects that represent different type of installation defects are observed by electric field simulation and different energizing and PD detection method. Several measurement issues related to the un-conventional PD measurement are also investigated. The investigation of all these important factors is performed to...

Large rotating machines in all kinds of applications ages due to operating stresses. Since many years the condition of stator insulation in these motors and generators is investigated using measurement of partial discharge (PD) and dielectric loss factor (tan delta). In particular, off-line and on-line methods of applying PD detection have...

During the last 50 years electricity demand has significantly increased. Large amounts of electricity are transported from the generation to the consumption sites. Overhead lines or underground cables are used to transport the required energy. High voltage levels are used to reduce the transmission losses. Power transformers are responsible for...

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...

Nowadays there are many partial discharge (PD) measurement systems on the market. There are systems that measure according to the IEC60270 standard (conventional measurement) and systems that don’t, the so called ‘’unconventional measurement systems’’. For PD measurement in power cables, measurement according to the standard has some...

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...

In many applications of high voltage engineering, electrical and thermal stresses increase due to an ongoing decrease of product dimensions. In particular, the electrical industry is interested in applying nanofluids in transformers to be able to decrease transformer size and weight. The requirement for nanofluids is to enhance the electrical...

With the current state of power electronic conversion operating at Direct Current (DC) can in some cases be more efficient than ordinary Alternating Current (AC). DC voltage energy transmission and distribution is, thus, playing an increasingly important role. The continuity of the electrical energy supply is essential for a well-functioning...

A large power transformer, is often, a custom designed equipment that entails a complex and capital intensive manufacturing process. It is an integral part of the power system and the cost of failure during service can be significant. Due to its importance in the power system, transformers should perform reliably under the conditions for which...

Standing time, prior to testing, is a necessary part of the oil-filled transformer manufacturing process and its duration is design dependent. Caution on part of the manufacturer to avoid failure of expensive transformers leads to the overestimation of standing time, consequently impacting annual production. Thus, a need for optimizing (reducing...

The acquisition parameters of an unconventional Partial Discharge (PD) measuring system affect the way the PD pulses are recorded and in turn, the results of the data processing. The noise based on the oscilloscope's vertical resolution is a feature of the sampled signal that is always present when a digital acquisition system is used. In PD...

Clustering techniques are of main interest for separation of partial discharge (PD) sources. The separation is achieved if it is possible to extract from the PD pulses specific information related to the source. In this sense, this paper explores the capability of fundamental quantities derived from PD current pulses such as the peak amplitude...
