On the assessment of voltage unbalance

Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010, 2010
The management of voltage unbalance in a power system is supported by the knowledge on the contribution of a single unbalanced load/source to the total level of voltage unbalance observed at a Point of Common Coupling (PCC) in an interconnected power system with unbalanced loads distributed all over.

SISTEM PENGAMAN MOTOR INDUKSI 3 PHASA TERHADAP GANGGUAN UNBALANCE VOLTAGE DAN OVERLOAD [PDF]

, 2011
The 3 phase induction motor is a motor type most often used in production processes in industry. This is because the induction motor has several advantages that are not owned by a DC motor, but often also occur among other disturbance Unbalance Voltage ...

Tradeoffs between AC power quality and DC bus ripple for 3-phase 3-wire inverter-connected devices within microgrids [PDF]

, 2011
Visions of future power systems contain high penetrations of inverters which are used to convert power from dc (direct current) to ac (alternating current) or vice versa.

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells

FEBS Letters, EarlyView.
Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.

Rancang Bangun Alat Monitoring Ketidakseimbangan Beban Pada Jaringan Tegangan Menengah

Jurnal Nasional Teknik Elektro, 2016
Load unbalance is a fault that can damage power transformers in medium voltage networks. The larger load or current unbalance cause heating at the transformer winding and can cause fatal damage if it occurs in a long time. One way to prevent this damage

Overview of three-phase inverter topologies for distributed generation purposes [PDF]

, 2010
The increasing presence of single-phase distributed generators and unbalanced loads in the electric power system may lead to unbalance of the three phase voltages, resulting in increased losses and heating.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Improving the Performance of Low Voltage Networks by an Optimized Unbalance Operation of Three-Phase Distributed Generators [PDF]

, 2019
This work focuses on using the full potential of PV inverters in order to improve the efficiency of low voltage networks. More specifically, the independent per-phase control capability of PV three-phase four-wire inverters, which are able to inject ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
