Emission Free Construction Site-Thermal Overloading of the Charging System
Akhlaq, Muhammad (Master thesis, 2022)In Norway, many municipalities set the target toward the emission-free construction site. Skagerak Energi also took a step toward this emission-free construction site by charging the construction machinery with the help ... -
Influence of skin- and proximity effects on LV fuse gear
Torsvik, Sandra (Master thesis, 2024)ABB in Skien produces compact transformer stations for the distribution grid. Depending on the application, these can come with a significant number of different configurations. Manufacturers must prove that every unit ... -
Non-intrusive ultrasonic sound detection of internal arc fault in medium voltage switchgear
Tollefsen, Tonje (Master thesis, 2021)Arc fault protection is becoming ever more critical for all power systems to maintain the safety of personnel and reduce damage to expensive equipment. An internal arc fault is an unintentional event within an enclosed ... -
Thermal capacity and loading assessment for 24 kV XLPE-insulated cables in air
Kwak, Hyeonyoung (Master thesis, 2021)Charging large battery packs requires high currents, especially for short-term charging of electric vehicles. The ohmic losses heats up power cables and is the limiting factor for the current capacity. However, the power ... -
Thermal overloading of MV metal enclosed switchgear
Gløsmyr, Cecilie Dortea (Master thesis, 2022)Going electric is an important step toward a more environmentally friendly world by reducing greenhouse gases. Some electrical devices might be able to withstand a short-term overloading, which for example can be used for ... -
Utilizing novel laser scanning techniques to anticipate PD inception voltages in HV cable interfaces
Korpås, Harald (Master thesis, 2024)High-voltage (HV) cable systems are the foundation for the transmission of electricity, but they are susceptible to partial discharges (PD), particularly at joint locations, which can cause insulation failure leading to ...
