Electric arcs are among the most dreaded fault scenarios in power supply engineering. They can be caused by a multitude of factors, such as aging of the insulation, environmental conditions as well as operating errors. Electric arcs can cause heavy damage to switchgear and present a serious hazard to operating personnel. The SIPROTEC 5 arc protection detects electric arcs through an optical sensor. Arcs are detected reliably and quickly as they develop, and the protective device can trip immediately and without delay times.
The arc protection module is part of the new SIPROTEC 5 series of modular, flexible and intelligent bay devices and can be used in the following device types:
Support of feeder automation applications, e.g. fault isolation and service restoration
