Proceedings ArticleDOI
Survey of smart grid concepts, architectures, and technological demonstrations worldwide
TL;DR: In this paper, the authors describe various smart grid concepts, architectures, and details of associated technological demonstrations implemented worldwide, and present drivers, visions and roadmaps to develop smart grids worldwide including China and India.
Journal ArticleDOI
Parameters Identification and Modeling of High-Frequency Current Transducer for Partial Discharge Measurements
TL;DR: In this paper, a lumped parameter model of RC is presented and an experiment-based methodology is developed to determine its parameters for detection and measurement of high-frequency (pulsed) signals such as partial discharge (PD) current pulses.
Journal ArticleDOI
Online Condition Monitoring of MV Switchgear Using $D$ -Dot Sensor to Predict Arc-Faults
TL;DR: In this article, the authors proposed an implementation of discrete wavelet transform (DWT) to de-noise the measured signals, and compared with a well-known infinite impulse response filtering technique.
Journal ArticleDOI
Wavelet-based de-noising of on-line PD signals captured by Pearson coil in covered-conductor overhead distribution networks
TL;DR: In this article, wavelet transform (WT) is suggested as a powerful technique to remove noise and disturbances from PD signals captured in CC overhead distribution networks, which are completely absorbed by electromagnetic interferences.
Journal ArticleDOI
Effect of Terminating Resistance on High Frequency Behaviour of Rogowski Coil for Transient Measurements
TL;DR: In this article, the effect of terminating resistance on the Rogowski coil model is analyzed based on theoretical, practical and simulated investigations. And the authors explore EMTP-ATP as an efficient tool to analyze and modify the transient behavior of Rogowski coils for high frequency pulse measurements.
