  • What is a fault and what are the different types? - USGS

    A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements over geologic

  • Bearing Fault Classification Based on Convolutional Neural

    Jul 28, 2021 · Convolutional Neural Network (CNN) has been widely used in bearing fault diagnosis and many satisfying results have been achieved. However, nearly all the published researches only focus on the classification accuracy, without considering another equally or even more important characteristic, classification uncertainty. The target of this research is to bridge this gap and to provide a

  • ELECTRICAL POWER SYSTEM FAULT ANALYSIS

    A fault at its terminals causes currents Ia, Ib and Ic to flow in the lines. If fault involves earth, a current In flows into the neutral from the earth. This current flows through the neutral impedance Zn. Thus depending on the type of fault, one or more of the line currents may be zero. a In b Ib1 Ic1 + + - -Ea Eb +-Ec n c Zn Fig.2 (a) Ia1

    Mar 06, 2021 · High Impedance Fault (HIF) is a problematic fault of feeders which its fault current is lower as compared to normal current in power system. Likewise, due to magnitude of impedance engaged in fault area and behavior of fault current is specific and not the same as the usual fault current profile which cannot be identified by standard relays. The HIF is created whenever a live conductor
