Simulation and analysis of single-phase grounding fault in small current grounding system
Journal of Physics: Conference Series, 2019 Abstract The characteristics and distribution of single-phase grounding faults in small current grounding system are not easy to capture, and it is not easy to collect and cover all possible situations in operation site. This paper builds a fault simulation model of distribution network based on PSCAD.

Advanced Engineering Materials, EarlyView.Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

Advanced Engineering Materials, EarlyView.This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6
Advanced Engineering Materials, EarlyView.The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

FEATURES OF A FAULTY PHASE AT SINGLE PHASE-TO-GROUND FAULTS
Electrical and data processing facilities and systems, 2022 Relevance Devices for determining the location of fault on power lines assume a known type of short circuit and faulty phases. However, their algorithms, as a rule, can not distinguish the faulty phase. Therefore, the determination of faulty phases during short circuits on power lines is performed by separate devices – faulty phase selectors.
