  1. 1. Interactive, Effective & Professional Comsol Applications : Based on COMSOL Modules Joule Heating & Corona Discharge

    University essay from

    Author : Axel Sigstam; Linus Olofsson; [2023]
    Keywords : COMSOL; Hitachi; applications; skin effect; joule heating; corona discharge; townsend;

    Abstract : This thesis will cover how two applications were developed using the commercial software COMSOL Multiphysics. The first application, the Joule heating application, simulates joule heating while taking the skin effect into consideration. The second application, the Corona Discharge application, is used to simulate corona discharges. READ MORE

  3. 2. Air and Silicon resistivity design space for dielectric simulations

    University essay from

    Author : Oscar Hammarberg; Anton Larsson; Adam Steiner; [2022]
    Keywords : electrical bushings; simulations; humidity; electrical breakdown; corona discharge; comsol multiphysics;

    Abstract : Electrical bushings are a type of hollow or solid conductor withinsulation designed to allow a conductor to pass through a conductingbarrier without making electrical contact and are very important forsafe transportation of electricity. The bushings vary in size, but allbushings have a solid or hollow conductor. READ MORE

  4. 3. Dielectric Response and Partial Discharge Characteristics of Stator Winding Insulation System with SiC Stress Grading

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Amar Abideen; [2020]
    Keywords : Stator Insulation; Dielectric Frequency Response; Polarization Depolarization Current; Insulation Modelling; FEM simulation;

    Abstract : The typical construction of a stator coil includes the use of end corona protection (ECP)coating, which is made of semi-conductive materials like silicon carbide (SiC). Thepurpose of ECP is to smooth the electric stress distribution near the slot exit, limitingthe electric field and partial discharge (PD) activity within the insulation system. READ MORE

  5. 4. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mohammadjavad Javadi; [2020]
    Keywords : Corona discharge; Suppression ring; High voltage capacitor banks;

    Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.

  6. 5. Investigating new Service System Solutions for High Altitude Balloons : Feasibility Study and Design Challenges

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Joakim Peterson; [2016]
    Keywords : High altitude balloon; service system; corona discharge;

    Abstract : The high altitude balloon operations at Esrange Space Center have been goingon since 1972, and about 550 launches have been performed. Their present service system for the high altitude balloons is about 18 years old. To be able to meet the requests from their customers, SSC have started the development of a new service system.
