1. Modularization of High Voltage Section
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Today, Alstom has several types of High-Voltage sections (HV), which are adapted for every new type of train. Some are very similar in size and components and others are more different. LÄS MER
2. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. LÄS MER
3. Strömmätsystem för 10 000 Ampere : Enligt Rogowskiprincipen
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : På RISE (Research Institutes of Sweden) finns en betydande kalibreringsverksamhet där avdelningen för högspänning önskar utöka sin strömmätningskapacitet för AC strömmar vid kraftfrekvens upp till 10 000 A. Syftet är att med hjälp av Rogowskiprincipen bygga en mätrigg för kalibrering av strömtransformatorer i fält. LÄS MER
4. Investigation of MIDEL 7131’s Dielectric Breakdown Strength and Thermal Behaviour : Master Thesis, an experimental study using concentric-like electrodes at elevated temperatures to study breakdowns
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Dielectric insulation are constantly exposed to various stresses, while also being expected to last for long periods of time. Naturally, they degrade with use and in demanding operational environments, this degradation phenomena can be accelerated, leading to costly consequences. LÄS MER
5. Early Anomaly Detection in Electrical Bushings Manufacturing at Hitachi Energy
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The manufacturing of electrical bushings for high voltages is complicated and highly demanding technology-wise. This process has more than 10 steps where a single mistake in the chain could cause a complete failure of the final product. A faulty bushing represents high costs to the company both economically and in terms of public image. LÄS MER
