Performance Problems of Non-Toroidal Shaped Current Transformers

Sensors, 2020
Nowadays, non-toroidal shape primary pass-through current transformers are commonly used for large current machines with several cables per phase. As these transformers exhibit no radial symmetry, it is not clear if they can be tested using the indirect ...

Prevention of the current transformer saturation by using negative resistance

IET Generation, Transmission & Distribution, 2021
In the power grid, various conditions may occur that saturate the core of a current transformer. Saturation of the protection core of the current transformers can cause a malfunction in the protection relays.

Impact of Permanent Magnet Field on Inductance Variation of a PMLSM [PDF]

, 2007
Analytical models of Surface Mounted Permanent Magnet Linear Synchronous Motors are generally presented with constant inductances. However, the impact of powerful rare-earth PMs in the saturation phenomena cannot be neglected anymore.

Saturation rate after vaccination against covid-19 [PDF]

, 2022
Introduction: Cormirnaty® was the first available vaccine in Europe that contains mRNA encoding the spike protein of SARS-CoV2. An enormous peptide commonality and thus molecular mimicry between SARS-CoV2 spike protein and human proteins could be shown.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Obtention of solar cell parameters, through convergence of iterative cycles. Part 1: Theoretical analysis and cycles proposal

Heliyon, 2022
In this Part 1 of this series of articles, two iterative cycles are proposed to accurately determine the shunt resistance (Rsh), the series resistance (Rs), the ideality factor (n), the light current (Ilig), and the saturation current (Isat) of solar ...
