IEEE Access, 2022 In the neutral ungrounded distribution network, the removal of permanent single-line-to-ground (SLG) fault easily leads to saturation of the electromagnetic voltage transformers (PT), which may cause ferroresonance overvoltage and PT failure.

Journal of Modern Power Systems and Clean Energy, 2023 Earlier studies have reported some calculation methods for commutation failure fault level (CFFL) in line-commutated-converter based high-voltage direct current (LCC-HVDC) system under single-line-to-ground (SLG) faults.

International Journal of Electrical Power & Energy Systems, 2007 This paper proposes a fault location method employing wavelet fuzzy neural network to use post-fault transient and steady-state measurements. When single line to ground fault (SLG) occurs in the distribution lines of an industrial system, the transient feature is distinct and the high frequency components in the transients can be employed to reveal ...

IET Generation, Transmission & Distribution, 2016 In high‐impedance grounded distribution networks which are common in many countries, single line‐to‐ground (SLG) fault diagnosis is difficult due to weak fault characteristics, noise interference, three‐phase unbalanced operation's influence and so on.

A Novel Protection Method for Single Line-to-Ground Faults in Ungrounded Low-Inertia Microgrids
Energies, 2016 This paper proposes a novel protection method for single line-to-ground (SLG) faults in ungrounded low-inertia microgrids. The proposed method includes microgrid interface protection and unit protection. The microgrid interface protection is based on the

IET Generation, Transmission & Distribution, 2021 Many sensors like digital fault indicators (DFIs) have been applied and promoted in distribution systems. The sensors can provide a technical mean for single‐line‐to‐ground (SLG) fault section location, but there are still some feature extraction and ...
