Arc Flash Risk Assessment Using Methodology FMECA

Paper deals with the Arc Flash Risk Assessment using methodology FMECA (Failure Mode Effects and Criticality Analysis). The aim of this paper is to develop a consistent 4-step model for an arc flash risk analysis and discuss the standard IEEE 1584™-2002 and the technical report BGI/GUV-I 5188 E (German Social Accident Insurance e.V. (DGUV)) used for action in the appraisal of potential thermal hazards due to electric fault arcs associated with electrotechnical work on electrical equipment. Calculated arc or incident energy is one of main inputs of the Arc Flash Risk Assessment. For the calculation based on the above mentioned methods was designed a computer program which was implemented in a programming language C++.
