Detection of internal and external faults of single-phase induction motor using current signature
, 2021 The main aim of this work is to analyze the input current waveform for a single-phase induction capacitor-run motor (SIMCR) to detect the faults. Internal and external faults were applied to the SIMCR and the current was measured.

A Location Method for AC Fault in LCC-HVDC System Based on Virtual Conduction Width Characteristics
IEEE Access, 2023 When an AC fault occurs in HVDC transmission system, the transient response change in the rate of change of current and voltage, which may lead to the unexpected action behavior of converter protection.
