Arc Flash in High Altitude Applications

    What impact would lower rH and quite high altitudes have on hazard distances and arc flash hazards in general? We are working on a 23 kV transmission system at 5000 meters in the Andes Mountains.

    At higher altitudes the voltage stress will definetly cause the air to electrically break down sooner at a lower voltage level(approx.2-10%).(google for these actual correction values/formula):)

    Thanks for the info. I have been Googling around but an having trouble finding definitive info as to how much impact it might have. Will keep looking.
