Field experiment using transient energy method to locate a single-phase to ground fault
Global Energy Interconnection, 2020 Distribution networks in China and several other countries are predominantly neutral inefficiently grounding systems (NIGSs), and more than 80% of the faults in distribution networks are single-phase-to-ground (SPG) faults.

A low-cost testing for transient faults
Ubiquity, 2006 Unconventional and low - cost software implemented testing technique for processor transient faults are briefly discussed here. On-line signatures of the Processor Status Register have been used here for detecting transient faults.

Multilevel Feature Extraction Method for Adaptive Fault Diagnosis of Railway Axle Box Bearing
Shock and Vibration, 2023 Railway axle box bearing fault signal contains high Q-factor resonance and low Q-factor transient shock components with periodic transient shock features that can characterize bearing faults. However, extracting fault features is usually difficult due to

Transient Fault Detection in Networked Control Systems [PDF]
International Journal of Distributed Sensor Networks, 2014 Transient faults appear unpredictablly and frequently in networked control systems (NCSs), which directly affect the safety of system. However, they can not be accurately identified due to various kinds of causes, so the detection of them needs more systematic and comprehensive system knowledge.

Single Terminal Transient Protection Scheme Based on Fuzzy Multi-criteria Fusion
Zhongguo dianliThe existing single-terminal transient protection schemes rely solely on single fault feature for fault identification, which leads to the poor identification reliability. This paper thus proposes a novel single-terminal transient protection scheme based
