  1. 1. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Sara Lenman; Sofia Blaad; [2023]
    Keywords : Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Abstract : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. READ MORE

  5. 4. Processing of Noisy Controlled Source Audio Magnetotelluric (CSAMT) Data

    University essay from Uppsala universitet/Geofysik

    Author : Julia Fridlund; [2019]
    Keywords : CSAMT; noise; magnetotelluric transfer functions; robust processing; transients; bias; CSAMT; brus; magnetotelluriska överföringsfunktioner; robust processering; transienter; bias;

    Abstract : Controlled Source Audio Magnetotellurics (CSAMT) is a geophysical method for characterizing the resistivity of the subsurface with the help of electromagnetic waves. The method is used for various purposes, such as geothermal- and hydrocarbon exploration, mineral prospecting and for investigation of groundwater resources. READ MORE
