A Visual Fault Detection Method for Induction Motors Based on a Zero-Sequence Current and an Improved Symmetrized Dot Pattern. [PDF]

open access: yesEntropy (Basel), 2022
Motor faults, especially mechanical faults, reflect eminently faint characteristic amplitudes in the stator current. In order to solve the issue of the motor current lacking effective and direct signal representation, this paper introduces a visual fault

Zero-Sequence Current in Cable Systems: A Study

open access: yesMansoura Engineering Journal, 2023
Large zero-sequence current is not a new phenomenon for cable bus duct systems; the question is what in fl uences its magnitude. It was found that the zero-sequence currents were circulating between different circuits in the cable system and that they ...

Zero-Sequence Current Suppression for Open-Winding Permanent Magnet Brushless Motor Driving System Based on Second Order Generalized Integrator

open access: yesIEEE Access, 2020
The open-winding driving system can improve power density and torque output capacity of the motor. However, the open-winding topology with a common direct current (DC) power supply provides a path for the zero-sequence current, which contributes to the ...

A Single-Phase-to-Ground Fault Detection Method Based on the Ratio Fluctuation Coefficient of the Zero-Sequence Current and Voltage Differential in a Distribution Network

open access: yesIEEE Access, 2023
Because the traditional zero-sequence overcurrent protection method is not effective in detecting single-phase-to-ground faults (SPGF) in a low-resistance grounded system (LRGS), this paper analyzes the fault characteristics of a 10-kV LRGS in detail ...
