  1. 11. Early Gear Failure Detection in Fatigue Testing of Driveline Components

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Govindraj Sannellappanavar; [2020]
    Keywords : Autoregressive modelling; Condition monitoring; Gear fault detection; Vibration analysis; Autoreggressiv modell; Feldetektering i växel; Tillståndsövervakning; Vibrationsanalys;

    Abstract : Early failure detection has been an integral part of condition monitoring of critical systems, such as wind turbines and helicopter rotor drivetrains. An unexplored application of early failure detection is fatigue testing of driveline components. READ MORE

  3. 12. DEVELOPMENT OF RISK INFORMED METHODS FOR ESTIMATING RADIATION RELEASE FROM CABLE FIRES AT HIGH ENERGY PHYSICS FACILITIES

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Daniel Funk; [2020]
    Keywords : Fire Safety Engineering; CERN; Fire-induced Radiological release; particle accelerator; Fire Protection; Fire Risk Analysis; Technology and Engineering;

    Abstract : CERN operates the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator. The LHC was built to advance the state of knowledge in particle physics by increasing the energy of colliding particles to the TeV range. READ MORE

  4. 13. Cross-Country Faults in Resonant-Earthed Networks

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

    Author : Gabriel Miguel Gomes Guerreiro; [2020]
    Keywords : Cross- country fault; resonant earthing; compensated network; MV network; distance protection; fault analysis; RTDS EMTDC.; dubbla jordfel; spoljordning; jordfelskompenserade elnät; mellanspänningsnät; distansskydd; reläskydd; RTDS EMTDC.;

    Abstract : Reliability requirements for power systems have been constantly increasing, as customers of electric power desire high power availability. In order to improve continuity of supply in medium voltage (MV) networks, utilities in many countries in Europe, North/South America and Oceania use resonant earthing and allow the operation of the network during a single phasetoearth fault for periods from several seconds up to several hours, since the earthfault current at the fault point in such systems is considerably reduced and is unlikely to damage equipment or create hazardous voltages for people or livestock.

  5. 14. Testing and analysis of an intelligent electronic device (IED) prototype for MTDC overhead line application

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

    Author : Ashen Gomes; [2020]
    Keywords : ;

    Abstract : A key problem faced with the implementation of a multi-terminal direct current (MTDC) grid is fault mitigation. One method extensively researched in mitigating a fault in MTDC is to use protection intelligent electronic devices (IEDs) and fast direct current circuit breakers (DCCBs). READ MORE

  6. 15. Modeling fault probability in single railroad turnouts in Eastern Region, Sweden, with the use of logistic regression models : A step from preventive to predictive preventive maintenance in railway maintenance planning

    University essay from KTH/Transportplanering

    Author : Filipp Zarov; [2019]
    Keywords : maintenance planning; railway turnouts; malfunction probability modeling; object-oriented databases; logistic regression models; underhållsplanering; spårväxlar; felsannolikhet modellering; objektorienterad databas; logistiska regressionsmodeller;

    Abstract : Turnouts are an important part of railway infrastructure for two reasons: infrastructure andmaintenance. For the infrastructure they provide the flexibility to allow the formulation and branchingof railway network and for maintenance they consume a large part of maintenance budget and have aprominent place in maintenance planning policy and activities.
