Abstract
A slipring with at least one slip ring module having at least one sliding track, and at least one wear indication track. A wear indication circuit is connected to the at least one wear indication track for monitoring electrical properties of the wear indication track and signaling an abnormal slipring condition. A wear indication track may be exposed to higher load, higher rotation speed, higher brush pressure force, or other lifetime-reducing influence as compared to a normal sliding track.
