Influence of Arc Faults on Pressure Production Characteristics in AC Turret of UHV Transformers

open access: yesHigh Voltage, EarlyView.
ABSTRACT The overpressure caused by arc fault in the oil tank can lead to a transformer explosion. Since the AC turret of transformers serves to connect the transformer windings with the AC busbar, the arc current can be extremely high if an earth fault arc occurs leading to potentially hazardous pressure.

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement

open access: yesHigh Voltage, EarlyView.
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

A pipeline for megahertz X‐ray photon correlation spectroscopy on soft matter samples at the MID instrument of European XFEL

open access: yesJournal of Synchrotron Radiation, EarlyView.
We present a standardized and highly automated pipeline for megahertz X‐ray photon correlation spectroscopy (MHz‐XPCS) on soft‐matter samples at the MID instrument of the European XFEL. The workflow addresses AGIPD petabyte‐scale data handling, detector‐artifact correction, correlation analysis and FAIR data output, enabling routine MHz‐XPCS with ...
