Top tips for selecting isolating spark gaps for hazardous areas

Friday, 16 August, 2013


Surges caused by a lightning strike, into exposed parts of a pipeline system, may lead to the dielectric strength of insulating joints being exceeded. As a result, hazardous sparking may occur or the insulation material may be damaged. Isolating spark gaps (ISG) and connection cables protect the insulating piece (insulation) against lightning-induced surges, and discharge the lightning energy without uncontrolled arcing in an explosive environment. The AfK recommendation No. 5 (1986 edition) was amended in accordance with the latest lightning current parameters according to IEC 62305. The new version now includes notes on the selection and inspection of isolating spark gaps including their connection elements. Download this white paper for recommendations on selecting isolating spark gaps for use in hazardous explosive environments for protection of insulating pipe joints.
