Partial Discharge Inception Voltage of Voids Enclosed in Epoxy/Mica versus Voltage Frequency and Temperature
(Journal article; Peer reviewed, 2020)Detection of partial discharges (PDs) is widely used as a condition assessment tool for high voltage equipment. Application of low frequency test voltage is often preferred in the case of test objects with a large capacitance. ... -
Partial Discharge Measurements for Studying Cavities in Mass Impregnated Cables
(Master thesis, 2012)A hypothesis regarding temperature dependant discharge levels was the starting grounds for this student work. Based on calculations and conversations with experienced people in this field, there should be cavity-induced ... -
Partial Discharge Testing and Prediction Modelling at High DC Voltage
(Master thesis, 2020)Internal partial discharges can be the cause of irreversible insulation degradation in High Voltage components, which can ultimately cause breakdown. Furthermore, they could become a condition indicator of the components, ... -
Partial Discharges and Breakdown Voltage in Designs with Triple Junctions under AC Stress.
(Master thesis, 2016)Today, manufacturers of medium voltage equipment are searching for alternatives to sulfur hexafluoride (SF$_6$) as the insulating gas. The advantageous thermal and molecular properties make it suitable as an insulating ... -
Partial Discharges in Narrow Gaps on Power Electronic Converter
(Chapter, 2014)The quest for power electronic converters to operate in a subsea pressurized environment that is completely filled with appropriate dielectric liquid brings about the need to study the insulation performance of liquid in ... -
Partial Discharges in Voids at Variable Voltage Frequency and Temperature Diagnostic Testing of Stator Mainwall Insulation
(Doctoral theses at NTNU;2020:143, Doctoral thesis, 2020)The main purpose of this thesis is to improve diagnostic testing by PD detection at variable voltage frequency by developing and experimentally testing theoretical models proposed for measurement of PDs in voids in a ... -
Partial Discharges on an Epoxy Surface due to Water Droplets
(Master thesis, 2011)Offshore wind turbines are exposed to a very harsh environment and can sustain significant damage during operation. In this thesis work, the possibilities of partial discharges in an insulation system of an offshore wind ... -
Partial Discharges under HVDC stress
(Master thesis, 2021)Sammenkobling av strømnett på tvers av Nordsjøen er en nødvendighet for å balansere et europeisk strømnett med stor grad av fornybare energikilder. Nettene kobles sammen ved hjelp av høyspente likestrømskabler, som kan ... -
Partial Orders in Representation Theory of Algebras
(Master thesis, 2008)In this paper we investigate some partial orders used in representation theory of algebras. Let $K$ be a commutative ring, $Lambda$ a finitely generated $K$-algebra and $d$ a natural number. We then study partial orders ... -
Partial oxidation of methane by chemical looping
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:232, Doctoral thesis, 2011)The catalytic partial oxidation of methane has recently received a great deal of attention as a process for production of synthesis gas. In this work, the catalytic partial oxidation was carried out anaerobically, in the ... -
Partial oxidation of methanol to formaldehyde in an annular reactor
(Peer reviewed; Journal article, 2021)A structured reactor with annular configuration was applied for studying methanol oxidation to formaldehyde over silver. By eliminating gas phase reactions, high formaldehyde selectivity (93–97%) was obtained at low methanol ... -
Partial Serre duality and cocompact objects
(Journal article, 2023) -
Partial-face Recognition using Patch-based Deep Learning: An experiment of face recognition on masked faces
(Master thesis, 2021)Behovet for delvis ansiktsgjenkjenning for å gjenkjenne delvis-ansikter fra CCTV-opptak eller andre bilder eksisterte siden fremveksten av teknologi. Når de prøver å gjøre en forbrytelse, dekker gjerningsmennene ansiktet ... -
Partially distributed optimization for mobile sensor path-planning
(Chapter, 2017)Mobile sensor platforms may provide low-cost, versatile means for obtaining high resolution information from spatially distributed processes. The aim of this paper is to efficiently calculate receding horizon-type motion ... -
