Arc Flash Protection: Guidance for Electrode Configuration Selection and A Sensitivity Analysis Based on IEEE Std. 1584-2018


Arc flash hazard prediction methods have become more sophisticated because the knowledge about the arc flash phenomenon has advanced since the publication of IEEE Std. 1584-2002. The IEEE Std. 1584-2018 has added parameters for more accurate arc flash incident energy, arcing current, and protection boundary estimation. The parameters in the updated estimation models include electrode configuration, open circuit voltage, bolted fault current, arc duration, gap width, working distance, and enclosure dimension. The sensitivity and effect changes of other parameters have been discussed in the previous literature but the importance of the selection of electrode configurations and enclosure dimensions is overlooked. According to the newly published model for incident energy (IE) estimation, the IE between VCB (Vertical Electrodes inside a metal Box) and HCB (Horizontal Electrodes inside a metal Box) can differ by a factor of two with other parameters constant. Using HCB as the worst-case scenario to determine the personal protection requirements may not be the best practice in all circumstances. This presentation will provide guidance for electrode configuration selection and sensitivity analysis for determining a reasonable engineering margin when the actual dimension is not available.
