Particle traps constructed on the insulator of conductive slip rings for surface flashover mitigation under particle adhesion

AIP Advances
The generation of abrasive particles is an unavoidable consequence of sliding electrical contact wear in conductive slip rings (SRs). The adhesion of abrasive particles to the insulators may lead to a decrease in flashover voltage, posing a risk to ...
