Arc flash study using ETAP
Arc flash study using ETAP
(OP)
I am trying to use ARC flash Analysis using ETAP 7.0 , but ETAP has limitation that the source Protective device shall be with in 20 bus from the faulted bus. Can we do the study if the Protective Device is away about 50 bus.
Can we apply arc flash analysis for the distribution overhead lines ? Please suggest

Many things may be possible, but not useful or sensible.

Are you modeling every pole on a long distribution line as a bus?
RE: Arc flash study using ETAP
I believe NESC (National Electrical Safety Code) Article 410 covers arc flash for overhead lines. IEEE 1584 and NFPA 70E covers equipment (enclosed??) up to 15kV. You may want to check with ETAP.
There are some other differences such as the overhead lines considers L-G fault currents vs. 3 phase as in IEEE 1584 and so on.

Possibly, depending on the software and the original intent of the model.
