The topic of arc flash has been highlighted by the most recent update to the Australian Wiring Rules (AS/NZS 3000:2007). Arc Flash Studies are used to estimate incident energy exposure from potential arc sources and to identify potential hazards under arc fault conditions. Studies combine short circuit calculations, empirical equations and protective device operating times to estimate incident energy and then determine risk levels and protective clothing requirements at typical working distances.

The arc flash study results are used to help prevent worker injury or death, avoiding litigation expenses, minimising equipment damage, minimising system down time, complying with codes and safety regulations (OSHA, NFPA, NEC) and meeting insurance requirements

PCE are experts in power system studies, have a wealth of experience and can undertake studies on behalf of clients. Once arc flash hazards are identified PCE can make recommendations and plans to minimise the risks posed by arc flash.
