Cable terminations are essential for connecting a cable to a piece of equipment such as a circuit breaker, transformer, motor, etc. Proper terminations are of great importance in order to provide faultless cable systems. Improper terminations could result in overheating, partial discharges, eventual breakdown, flashover and breakdown in the...

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...

Partial Discharges(PD) are commonly produced in defects within the insulation systems of high voltage equipment. These discharges are typically nanosecond current pulses in the amplitude range of milli-amperes. A long term exposure of the insulation system to these partial discharges accelerate the aging mechanisms that eventually lead to the...

The phenomenon of partial discharge has been long studied in various power components and in recent times, it has been agreed that the occurrence of such discharges can be considered as a vital parameter of component health. Partial discharges in power cables is a pervasive phenomenon that over time may lead to...

To enable the next generation subsea boosting and processing facilities, high power electrical connectors are strongly needed and considered one of the most critical components of the system.
Electrical tree growth is a precursor to electrical breakdown in high voltage insulation materials. Therefore, the study of the tree growth dependency...

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...

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...

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...

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...

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...

Kanas, V. (author)
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...

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...
