The Recognition of Fires Originating from Photovoltaic (PV) Solar Systems [PDF]
There has been an observable increase in the fitting of photovoltaic (PV) solar panels on the roofs of buildings in the UK over the last decade. The origin of some fires in domestic and commercial properties has been attributed to PV systems.

Testing System for the On-Site Checking of Magneto-Thermal Switches with Arc Fault Detection
Arcing is a harmful condition that can lead to electrical fires. The U.S. National Electrical Code requires the installation of electric arc breakers in all residential areas. However, such devices can fail, and therefore, may not work when needed.

Field Emission Dark Current of Technical Metallic Electrodes
In the framework of the Low Emittance Gun (LEG) project, high gradient acceleration of a low emittance electron beam will be necessary. In order to achieve this acceleration a -500 kV, 250 ns FWHM, pulse will be applied in between two electrodes.

Secondary Arc Extinction in Extra High Voltage Systems Using Grounding Switches
Long Extra High Voltage (EHV) transmission systems tend to bring a pronounced state of secondary arcing. Therefore, an essential pre-requisite for single-phase-switching application, is the possibility and speed of secondary arc final extinction during ...

Novel Series Arc Fault Detector Using High-Frequency Coupling Analysis and Multi-Indicator Algorithm
In the field of arc fault detection, it is universally acknowledged that it is very hard to judge whether there is an arc fault through signals of the main line when a masking load (such as air compressors, lamps with dimmers, and so on) is in parallel ...
