Abstract: Low fault currents, associated with Vegetation High Impedance Fault (VeHIF) events, are often challenging to clear by relying on traditional overcurrent based protection schemes. Low Frequency (LF) harmonics have readily been used in the literature… read more here.

Abstract: This letter exhibits the presence of High-Frequency (HF) current signatures of arcing in Vegetation High Impedance Fault (VeHIF) events. Zero-crossing arcing discontinuities are shown to have varying widths causing different levels of HF noise bursts… read more here.
