Design of Three Phase Load Unbalance Automatic Regulating System for Low Voltage Power Distribution Grids

open access: yesMATEC Web of Conferences, 2018
In the three-phase four wire system of the low voltage side for the distribution grid, the phenomenon of asymmetrical and uneven single phase load were very common, causing unbalance in certain network.

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Machine Learning Techniques to Predict Voltage Unbalance in a Power Transmission System

open access: yesIEEE Open Journal of Industry Applications
Voltage unbalance is a growing issue that, among other things, can impact three-phase motor and drive loads, result in nuisance tripping of generation units and capacitor banks, and prevent optimization of conservative voltage regulation strategies. This

Intercompartmental communication in senescence

open access: yesFEBS Open Bio, EarlyView.
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

Power quality improvements through power electronic interfaced distributed generation [PDF]

open access: yes, 2010
In low-voltage distribution networks a large amount of single-phase nonlinear loads are connected. This leads to the combined presence of power system unbalance and harmonic distortion.
