Wihartady, H. (author)The short circuit arc is the most dominant fault in the power system that leads to single phase to ground fault. South Sumatera 150 kV system in Indonesia consists of two different string insulator types in the transmission line, with and without arching horn. In this study, some fault situations in that system is reconstructed by using ATP Draw...master thesis 2009

Dakhlan, D.F. (author)The thesis describes the modeling of the internal faults in three-phase three-winding power transformer related to the differential relay protection behavior due to those faults. This transformer model is based on the mutually coupled [RL] matrix and entirely compatible with ATP/EMTP software. The model uses the real power transformer and the...master thesis 2009

Sihombing, H. (author)The ambient conditions could influence the breakdown strength of gas insulated substation. It is important to check if this influence will put the GIS into severe condition, especially in the presence of protrusion. A risk assessment is thus important for making decision if the GIS is safe to be operated.master thesis 2009

Nie, L. (author)Wind energy promises to become an important source of energy in the near future. Penetrating large-scale wind power into power systems presents a lot of challenges to power system operators, generation companies and wind turbine manufactures. In order to design less expensive and more efficient wind turbines, manufacturers have tried a lot of...master thesis 2009

Firmansyah, M. (author)The concentrated winding is proposed to replace the distributed winding due to the advantages in a manufacturing process. It is easily wounded by a machine in the former and the impregmentation process that can be carried out separately for each individual coil. These advantages can lead to the automation process in winding processes, reduced...master thesis 2009

Gebrekiros, Y.T. (author)This thesis deals with characterization of epoxy nanocomposites with different filler types and filler percentages by performing space charge measurements and DC ramp breakdown tests. The space charge measurements were performed at three field levels (10, 15, and 18 kV/mm) using the PEA method. The results were then analyzed. In addition to this...master thesis 2009

Louh, A. (author)The Dutch electricity grid is considered one of the most reliable in the world. However in the near and far future, significant changes will occur, that will endanger its stability, reliability and safety. Introduction of an embedded wireless sensor network, to determine the state of the power system at any time, in order to cope with these...master thesis 2009

Setyawan, J. (author)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...master thesis 2009

Van Oosterom, J. (author)A solution is investigated for an auxiliary power supply for the HISPEM project, where a DC/DC converter is needed which is fed by a 540 V DC bus and has an output voltage of 12 V DC. A design using the flyback converter is made, using two different solutions to deal with the relative high input voltage.master thesis 2010

Hong Viet Phuong, N. (author)Nowadays, the amount of distributed generation (DG) units is increasing rapidly. Most of them are represented by microturbines, combined heat and power (CHP) plants and synchronous generator. At this moment, IEEE 1547 standard states that DG clearing time should be based on the during-fault voltage range. However, DG units will be required to be...master thesis 2010

Imoru, O. (author)The principle of Inductive Power Transfer (IPT) is very old but it is rarely used for transferring power from source to load via a medium. This is because normally the medium restricts the power transfer due to losses or the shielding effects. However, for low energy applications, an acceptable amount of power could be transferred from the...master thesis 2010
