Behavior of current transformers under distorted waveforms

9th Brazilian Congress on Metrology (Metrologia 2017) 26–29 November 2017, Fortaleza, CE, BrazilThe use of nonlinear loads connected to the power networks that produce distorted currents has been increased in the last years. At the same time, distributed

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

Clinical Impact of NOTCH3 Variant Location After First Stroke in CADASIL

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Despite its monogenic origin, Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy exhibits marked variability in clinical expression and severity. Variants in the NOTCH3 gene, within epidermal growth factor‐like repeat domains 1–6 or 7–34, are known to influence disease onset, but their impact ...

A statistical analysis of metal oxide varistor current under distorted supply voltage conditions

, 2014
: Leakage current monitoring is still relied upon when on-site condition assessment or stability analysis of metal oxide varistors is to be conducted. The non-availability of adequate testing equipment, capable of directly measuring resistive component ...

Iron Losses Prediction with PWM Supply Using Low and High Frequency Measurements: Analysis and Results Comparison [PDF]

, 2008
In this paper, two different methods for iron loss prediction are analyzed. The first method is based on the classical separation of loss contributions (hysteresis, eddy-current, and excess losses).

Routine Testing–Oriented Method for Evaluating Inductive Current Transformers Accuracy Under Harmonic Distortion, Based on Maximum Current Error and Phase Displacement

IEEE Access
In the case of the modern inductive current transformers the most important factor that have influence on their wideband accuracy is the self-distortion of the secondary current caused by the nonlinearity of the magnetization characteristic of the ...

White Matter Microstructural Abnormalities in Neonatal Onset Genetic Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Recent evidence indicates that epilepsy is associated with abnormal white matter. If seizures alter white matter, then the impact upon network function, epileptogenesis, and cognition could be pronounced in neonates undergoing rapid developmental myelination. Neonates with epilepsy due to nonstructural genetic causes provide a unique

Harmonic assessment‐based adjusted current total harmonic distortion

The Journal of Engineering, 2016
Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...
