Document Type and Number:
WIPO Patent Application WO/2016/059105
Kind Code:
A3
Abstract:
A slip ring has at least one slip ring module having at least one sliding track, wherein the slip ring has 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 slip-ring condition. The at least one wear indication track may be exposed to higher load, higher rotation speed, higher brush pressure force, or other lifetime-reducing properties compared to a normal sliding track.
