Wideband Self-Calibration Method of Inductive CTs and Verification of Determined Values of Current and Phase Errors at Harmonics for Transformation of Distorted Current

open access: yesSensors, 2020
Self-calibration of a designed wideband inductive current transformer (CT) was carried out in the ampere-turns condition. This method does not require a reference transducer. The values of current and phase errors at the harmonics of frequencies from 100

Switching Pattern Improvement for One-Cycle Zero-Integral-Error Current Controller

open access: yesIEEE Access, 2022
The one-cycle current control is a non-linear technique based on the cycle-by-cycle calculation of the ON time of the power converter switches. Its application is not common in tracking fast-changing reference currents, due to the necessity of fast and ...

Design of the RLG Current Stabilizer Circuit for Attitude Control in the Satellite [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2006
In this paper, we describe the RLG current stabilizer circuit for attitude control in the satellite. The RLG makes use of the Sagnac effect within a resonant of a HeNe laser.

On the uncertainty of stream networks derived from elevation data: the error propagation approach [PDF]

open access: yes, 2010
DEM error propagation methodology is extended to the derivation of vector-based objects (stream networks) using geostatistical simulations. First, point sampled elevations are used to fit a variogram model.

Development of Inductive Current Transformer 400/5/1 of Class 0.2S for Frequency Range 50 Hz–5 kHz

open access: yesSensors
This paper is devoted to the development of a window-type inductive current transformer (iCT) with a rated primary current equal to 400 A and two secondary windings with rated currents of 5 A and 1 A. Its novelty concerns the presentation of this process

Error calculation of broadband standard current transformer based on equal-ampere-turn principle

open access: yesEnergy Reports, 2022
Due to the lack of corresponding devices and traceability systems for wide-band current transformer verification, the wide-band current measurement requirements of many power systems cannot be solved.

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...
