A High-Precision Error Calibration Technique for Current Transformers under the Influence of DC Bias
Energies, 2023 A bias current in the power system will cause saturation of the measuring current transformer (CT), leading to an increase in measurement error. Therefore, in this paper, we first conducted measurements of the direct current component in a 10 kV ...

Simulation of longitudinal differential protection of transmission lines with additional stabilization and APU system [PDF]
Tehnika, 2016 This paper explains the algorithm for the longitudinal differential protection of transmission lines with automatic reclosing. Classic stabilization is not sufficient for avoiding of unnecessary operations caused by saturation of current transformer ...

Current saturation and Coulomb interactions in organic single-crystal transistors [PDF]
, 2008 Electronic transport through rubrene single-crystal field effect transistors (FETs) is investigated experimentally in the high carrier density regime (n ~ 0.1 carrier/molecule). In this regime, we find that the current does not increase linearly with the

Eddy Saturation of Equilibrated Circumpolar Currents
Journal of Physical Oceanography, 2013 Abstract This study uses a sector configuration of an ocean general circulation model to examine the sensitivity of circumpolar transport and meridional overturning to changes in Southern Ocean wind stress and global diapycnal mixing. At eddy-permitting, and finer, resolution, the sensitivity of circumpolar transport to forcing magnitude

Fast Detection of Current Transformer Saturation Using Stacked Denoising Autoencoders
Energies, 2023 Malfunctions in relay protection devices are predominantly caused by current transformer (CT) saturation which produces distortion in current measurements and disturbances in power system protection.
