What method do you use for 3 Phase Arc Flash Studies < 15 kV? |

I voted IEEE 1584, but it needs to be qualified. We don't use IEEE 1584 for all < 15 kV analyses. For overhead medium voltage distribution (>1 kV), we use ARCPRO software. |

Same comment as jghrist, but it is considered a single phase event. |

I probably could have been more clear about this. I meant for 3 Phase systems. This is the first of what will likely be a weekly or bi-weekly survey question. It should help everyone see what the "industry norm" is for certain issues. - At least the norm according to the forum users. Thanks Everyone! |

We are using the NFPA 70E tables as a starting point until a full software analysis can be performed. |

We use ARCPRO for 3Ø overhead systems. We only consider 1Ø faults. |

So much for making a quick post when rushing off the airport this morning. Yes, I meant 3 phase arc flash modeling. |

Gentlemen, Thanks for the feedback. Jim, this is a great idea. Keep the surveys comming. Bob Ragsdale P.E. |

Our software is based on IEEE 1584 and that is what we use as an industry standard. It would be interesting if anyone is using NFPA 70E calculations for systems above 600V, I don't believe that is recommended anymore. |
