MV ground fault analysis and global grounding systems

, 2004
In 1999 the Italian Standard CEI 11-1, based on the CENELEC HD 637 S1 Standard, introduced, with reference to MV distribution systems, the notion of "global grounding systems", i.e.

Interferences Between Grounding Systems In Urban And Industrial Areas

, 2015
In city centers, urban or industrial areas, the grounding systems (GSs) interact naturally because they share common zones of influence. IEC Standard 61936-1 defines the “global grounding system” (GGS), as consisting of elements that are essentially ...

Marked Long‐Term Improvement in Lung Function in Melanoma Differentiation–Associated Protein 5 Antibody–Positive Dermatomyositis Patients: Experience of a Single‐Center Longitudinal Cohort in North America

Arthritis Care &Research, EarlyView.
Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation–associated protein 5 (MDA5) antibody–associated dermatomyositis (DM). Methods Thirty patients with MDA5 antibody–associated DM were identified in a single‐center longitudinal cohort of 352

Grounding Fault Protection Scheme for 0.4 kV Switchgear in Metro Substations

Chengshi guidao jiaotong yanjiu
［Objective］ Single-phase grounding faults account for over 80% of the total distribution line faults, with most inter-phase faults originating from single-phase grounding faults.

Thin Conductor Modelling Combined with a Hybrid Numerical Method to Evaluate the Transferred Potential from Isolated Grounding System

Energies, 2019
Grounding systems are essential parts of substations and power generation stations. The evaluation of transferred potentials from an active grounding system to other passive ones or to any near conductors is an important aspect to be considered, because ...

Interferences phenomena between separate grounding systems

, 2013
One of the main purposes of grounding systems is to safely inject fault currents into the soil; such currents flow through any buried conductive objects (e.g., other earth electrodes) eventually present along their path to the source.

Understanding of Grounding Systems' Performance with Equivalent Circuit Model

, 2021
It has been known that under high impulse conditions, a non-linearity in some practical grounding electrodes, subjected to fast surges was observed. Inductive component can also be significant in grounding electrodes subjected to high impulse conditions,

Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.
