Carbon dust can complete a low voltage path and thereby initiate a low voltage arc that has absolutely nothing to do with altitude. Why and if brushes act worse in (high altitude) service will have to be answered by someone else.< The issue is with the increased amount of carbon dust created due to the nature of the brushes, there is greater likelihood of an arcing path tracking the powder. Less dense air will permit an arc to jump a greater distance than at sea level pressure.
