Detection method on pantograph-catenary arcing of electric locomotives based on multi-frequency-band characteristics of current signals

机车电传动
Detecting pantograph-catenary arcing on trains is crucial for ensuring safety in railway operation and maintenance. Most existing detection methods rely on optical instruments to capture pantograph-catenary images, followed by the analysis of these ...

Influence of buffer volume on the effect of pressure relief for the metal‐enclosed switchgear due to arc fault

IET Generation, Transmission & Distribution
The explosion accident due to the internal arc fault in the metal‐enclosed switchgear cannot be ignored. Therefore, improving the ability of switchgear to resist the arc fault has important significance.

Arc mapping [PDF]

, 2010
Establishing a compartment fire's area of origin when it has been burning at post-flashover conditions is a difficult process. Burn patterns traditionally used by fire investigators following post-flashover fires can be erroneous.
