I have a small DC generator (motor driven) that provides field voltage and current to a hydroelectric generator. The brushes started arcing and we changed brushes and seated the brushes, however there is still arcing. Anyone have additional hints for why it's still arcing and what's the fix? There have been no load changes, it's been running at full load for the past several weeks.
Cheers in Advance
