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 ...

Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
, 2011 The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

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.

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

When Current Does Not Follow Bonds: Current Density in Saturated Molecules [PDF]
The Journal of Physical Chemistry C, 2019 The tools commonly used to understand structure–property relationships in molecular conductance, interatomic currents and conductance eigenchannels, generally give us a sense of familiarity, with the chemical bonding framework and molecular orbitals reflected in the current.

Mechanism for Current Saturation and Energy Dissipation in Graphene Transistors [PDF]
Physical Review Letters, 2010 From a combination of careful and detailed theoretical and experimental studies, we demonstrate that the Boltzmann theory including all scattering mechanisms gives an excellent account, with no adjustable parameters, of high electric field transport in single as well as double-oxide graphene transistors.
