PowaArc®
PowaArc is used to provide guidance on the arc fault containment capability of switchboards. The calculation methodologies used are based on a combination of theoretical physical laws, empirically derived rules and calibrations against case studies. The output of this tool is a likelihood rating of possible switchboard failure due to an arcing fault, for use in risk assessments. Categories used for calculated panel and fixing tensile rupture risks are:
Low: Below yield strength value.
Medium: Between yield strength and ultimate tensile strength values.
High: Above ultimate tensile strength value.
