The 2002 NEC implemented new requirements to help reduce the number of electrical fires caused by parallel arc faults in branch circuit wiring. All branch circuits supplying bedrooms in single-family ...
Commonwealth Edison (ComEd) conducted a survey of the utility industry on how to determine energy created during arc flash events. The limited information available focused on selecting arc-rated ...
Germany's Fraunhofer ISE announced it published a new international test standard for inverters that incorporate arc fault detection devices. The research institute said the new IEC 63027 standard ...
In arc fault circuit breakers, the choice of a fault detection sensitivity is generally made as a compromise between speed of detection and avoidance of nuisance trips. By using solid state switching ...
Schweitzer Engineering Laboratories, Inc. (SEL) has announced the immediate availability of arc-flash detection capability in the SEL-751A Feeder Protection Relay, Schweitzer Engineering Laboratories, ...
Introduction of higher DC system voltage distribution networks greater than 24V in future passenger vehicles appears to be an unavoidable consequence of meeting the increasing future electrical power ...
Electrical distribution needs are continuously evolving in residential, commercial, and industrial sectors. Owning to this, the demand for electrical power is on the rise, indicating the probability ...
The new IEC standard 63027 will eliminate some of the weaknesses of the old UL 1699B standard, which did not simulate real operation sufficiently. Image: Fraunhofer ISE German research body Fraunhofer ...
