Fault detection in transmission networks of power systems
TL;DR: In this article, an online fault detection scheme for a sample power system is introduced based on the use of a variable structure system called "sliding mode observer" where information contained in the output measurements is utilized to detect the onset of faults in the transmission network of the sample power systems in real time and online.

Detecting arcing downed-wires using fault current flicker and half-cycle asymmetry
TL;DR: In this paper, a simple approach was taken to design an arcing fault detector, which utilizes the random behavior of the fault current, and calculated the asymmetry of the current by comparing the positive and negative current peaks in one cycle to those in the next cycle to measure the flicker in the current signal.
