DESCRIPTION:Arc flash hazard prediction methods have become more sophistica
 ted because the knowledge about the arc flash phenomenon has advanced sinc
 e the publication of IEEE Std. 1584-2002. The IEEE Std. 1584-2018 has adde
 d parameters for more accurate arc flash incident energy\, arcing current\
 , and protection boundary estimation. The parameters in the updated estima
 tion models include electrode configuration\, open circuit voltage\, bolte
 d fault current\, arc duration\, gap width\, working distance\, and enclos
 ure dimension. The sensitivity and effect changes of other parameters have
  been discussed in the previous literature but the importance of the selec
 tion of electrode configurations and enclosure dimensions is overlooked. A
 ccording to the newly published model for incident energy (IE) estimation\
 , the IE between VCB (Vertical Electrodes inside a metal Box) and HCB (Hor
 izontal Electrodes inside a metal Box) can differ by a factor of two with 
 other parameters constant. Using HCB as the worst-case scenario to determi
 ne the personal protection requirements may not be the best practice in al
 l circumstances. This presentation will provide guidance for electrode con
 figuration selection and sensitivity analysis for determining a reasonable
  engineering margin when the actual dimension is not available.\n\nSpeaker

X-ALT-DESC:Description: <br /><p>Arc flash hazard prediction methods have b
 ecome more sophisticated because the knowledge about the arc flash phenome
 non has advanced since the publication of IEEE Std. 1584-2002. The IEEE St
 d. 1584-2018 has added parameters for more accurate arc flash incident ene
 rgy\, arcing current\, and protection boundary estimation. The parameters 
 in the updated estimation models include electrode configuration\, open ci
 rcuit 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 im
 portance of the selection of electrode configurations and enclosure dimens
 ions is overlooked. According to the newly published model for incident en
 ergy (IE) estimation\, the IE between VCB (Vertical Electrodes inside a me
 tal 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-cas
 e scenario to determine the personal protection requirements may not be th
 e best practice in all circumstances. This presentation will provide guida
 nce for electrode configuration selection and sensitivity analysis for det
 ermining a reasonable engineering margin when the actual dimension is not 
 available.&nbsp\;</p>
