Arc Fault Protection System in Low-Voltage Installations for Protecting Installations and Persons
Keywords:
arc fault, arc detection, short-circuiter, protection of installations, live workingAbstract
Overcurrent protective devices are often not sufficient to protect installations and persons from the ef-fects of arc faults. Fast active protective devices, which limit the arc duration to some milliseconds, pro-vide significantly increased protection. This article deals with the design of and requirements on such an active protection system, which consists of an arc detection device and a short-circuiter. Both fixed in-stallation and a mobile arrangement of the system will be presented.
