Time–frequency characteristics and influencing factors of the pressure wave caused by power–frequency arc inside a closed oil tank

High Voltage, EarlyView.
Abstract The arc faults inside oil‐immersed power equipment can produce high‐amplitude pressure waves inside tanks, which might cause ignition and explosion accidents. This kind of failure is one of the most severe faults for power equipment and has attracted considerable attention in recent years.

High‐speed dynamic sensing and analysis of high voltage circuit breaker spring‐operating mechanism

High Voltage, EarlyView.
Abstract Diagnosing the operational status of High‐voltage circuit breakers (HVCBs) is crucial for ensuring the safe and stable operation of the grid. Mechanical characteristic parameters are effective indicators for evaluating the performance of HVCBs.

Impact of Component Structure on Vibration and Noise of Converter Transformers Under Harmonic Excitation

High Voltage, EarlyView.
ABSTRACT The internal component structure of the converter transformer plays an extremely important role in the generation and propagation of vibration noise. In order to comprehensively reveal the influence of the component structure on the vibration and noise of converter transformers, this paper conducted vibration and noise experiments on different

Comparison of time‐of‐flight and MIEZE neutron spectroscopy of H2O

Journal of Applied Crystallography, EarlyView.
We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time‐of‐flight spectroscopy, a conventional neutron scattering method. The basis of this comparison is provided by measurements performed on pure water under the same measurement conditions.We report a comparison of modulation of ...

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.
