Electric Heating of Subsea Pipelines: Design and Testing of an Applicable Ring Core Transformer
(Master thesis, 2013)As it becomes profitable to extract oil and gas from smaller and smaller reservoirs, jumpers (t-offs) connected to the main pipelines become necessary. This master?s thesis has investigated a simple transformer design which ... -
Electric hydraulic interaction
(Master thesis, 2011)The hydraulic models representing hydro turbines and conduit system found instandard model libraries of power system analysis tools are often simplied mod-els. Subsequently, important information about the dynamics of the ... -
Electric Motor Development for Shell Eco-Marathon: Manufacturing an ironless axial flux permanent magnet Motor with Hallbach array and Development of existing Motor for the Shell Eco-Marathon Competition
(Master thesis, 2012)This thesis describes the process of making a new engine for the car DNV Fuel Fighter 2 that participated in the Shell Eco-Marathon Europe 2012 in Rotterdam. The decision was made to construct a new engine based on an ... -
Electric Propulsion System for the Shell Eco-marathon PureChoice Vehicle: Controlling the lights and alternative storage devices such as batteries and supercapacitors
(Master thesis, 2008)This report is divided into six main chapters. It starts off with an introductory chapter explaining the different propulsion strategies that have been considered during the last semester, and the final propulsion system ... -
Electric steam methane reforming - Economical and environmental implications of replacing methane with electricity for heating in a steam methane reformer
(Master thesis, 2021)Grønn energi har fått en trekkraft som et resultat av økt fokus på bærekraft, og det blir forsket på mer enn noen gang før. Ettersom fossile brennstoff er skadelig for miljøet, er det på tide at de byttes ut. Hydrogen er ... -
Electric Storage Possibilities in the Future Power System
(Master thesis, 2013)In recent years, the amount of renewable energy sources in Europe has increased substantially. During the work on this thesis, wind and solar energy is added to the simulating tool, PSST. Where wind and solar energy are ... -
Electric stress-induced slip lines in jammed particle monolayers
(Peer reviewed; Journal article, 2016)Drops fully covered by particles, so called Pickering emulsion drops, are used to stabilize emulsions and are ideal templates for producing particles and advanced capsules. Recent studies show how electrohydrodynamic ... -
Electric Traction Power System Stability: Low-frequency interaction between advanced rail vehicles and a rotary frequency converter
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:56, Doctoral thesis, 2010)Low-frequency instability in AC electric traction power systems has come to be a concern in recent years. Power oscillations in the range of 10-30 % of the system’s fundamental frequency are reported from all over the world ... -
Electric Utility Customer Segmentation from Advanced Metering Systems Data
(Master thesis, 2020)Denne masteroppgaven er skrevet for Institutt for elkraftteknikk ved Norges teknisk-naturvitenskapelige universitet (NTNU), Trondheim, i samarbeid med Lyse Elnett AS og Centre for Intelligent Electricity Distribution ... -
Electric vehicle charging and end-user motivation for flexibility: a case study from Norway
(Journal article; Peer reviewed, 2021) -
Electric water heaters as flexible energy resources in the power grid
(Master thesis, 2023)Usammenhengende kraftproduksjon fra vind- og solenergi kan være utfordrende for strømnettet. Forbrukerfleksibilitet fra aggregerte elektriske varmtvannsberedere er en lovende løsning for å håndtere denne utfordringen, ... -
Electric-field-induced annihilation of localized gap defect states in amorphous phase-change memory materials
(Peer reviewed; Journal article, 2022)Structural relaxation of amorphous phase-change-memory materials has been attributed to defect-state annihilation from the band gap, leading to a time-dependent drift in the electrical resistance, which hinders the development ... -
Electric-field-induced structuring and rheological properties of kaolinite and halloysite
(Journal article, 2013)Electric-field-induced structuring of kaolinite and halloysite particles was studied in respect to their electrorheological (ER) response in silicone oil and in paraffin dispersions. The structural and morphological ... -
Electric-Hydraulic Interaction - Impact of Hydraulic Properties on Stability in Isolated Operation
(Master thesis, 2016)The models for hydraulic systems found in standard Power System Analysis tools are often based on simplified mathematical models. These simplifications may lead to inaccurate representations of the dynamic behaviour of ... -
