Combined Cycle Journal - How to solve brush and brush holder problems
Cutsforth Inc's Mike Biroschak conducted a short clinic on common brush and brush holder problems and how to deal with them. He closed out his presentation with a solution for bearing wear and tear caused by ineffective shaft grounding systems.
Biroschak began by saying that the buildup of carbon deposits in brush holders is the primary cause of collector-ring fires.
Combined Cycle Journal - Prevent the damaging effects of stray voltages on rotating shafts
Some rotating machines, because of their electrical or mechanical characteristics, induce an electrical potential (voltage) on their shafts during
operation. Experts at Bently Nevada, Minden, Nev, warn that if this voltage is not managed, or if the grounding system fails, the voltage seeks an alternative path to ground. That path is the metal component closest to the shaft—typically a bearing or seal.

Power Engineering - Brush Holder System Minimizes Opportunity for Collector Ring Wear
Most power plant operators are familiar with generator maintenance problems such as collector rings going out of round and photographing on the ring surface. The primary cause of collector ring wear is improper contact pressure between the brush and the ring. Too much pressure causes excessive mechanical wear. Too little pressure causes electrical wear. read more>>
