Signal Extraction and Clustering of Partial Discharge in Motor Insulation Using Temporal Correlation‐Based Clustering

High Voltage, EarlyView.
ABSTRACT As one of the important links in energy transition and global energy interconnection, electric vehicles (EVs) are becoming increasingly major research topics in the field of energy. Partial discharge (PD) identification under repetitive impulsive voltages plays a pivotal role in evaluating the health of electric vehicle (EV) motor insulation ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Study on the Coupled Effects of High‐Speed Airflow and Charged Sand on Power‐Frequency Discharge Characteristics of Conductor–Tower Gaps in Strong Wind–Sand Environments

High Voltage, EarlyView.
ABSTRACT Strong wind–sand weather in Xinjiang threatens power grid safety by increasing transmission line tripping risks. Existing studies focus on sand polarization but neglect the coupled influence of high‐speed airflow and charged sand on gap discharge characteristics.

Investigation of the Partial Discharge Inception and Flashover With IEC‐Based Comparative Tracking Index Electrodes and Comparison With Homogeneous and Inhomogeneous Electric Fields at Varying Pressures for Aerospace Applications

High Voltage, EarlyView.
ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.

One million scans later: the evolution of the I16 material and magnetism beamline at Diamond Light Source

Journal of Synchrotron Radiation, EarlyView.
Beamline I16 at Diamond Light Source is a versatile X‐ray scattering instrument that combines tunable X‐ray energy and polarization, flexible diffraction geometries, and advanced sample environments for studies of electronic, magnetic, and structural phenomena.Here, we review the capabilities of beamline I16 at Diamond Light Source after nearly 20 ...
