slip rings [RE-wrenches]

[Clive Wilkins, PowerSense]

Hi,  Haven`t had any problems with the one Proven without slip rings  here,
only problem I`ve heard of is cable snarling up with the brake rope.

Out of the 50 plus turbines with slip rings only one caused any
problem......owner induced...Hadn`t received any maintenance for 3 years!

Having been brought up with slip rings and brushes on gensets, I make sure
brush calipers are working freely and lub. them..WD40 and that brushes are
seated properly on the ring.
Not really a subject to get your knickers in a twist over chaps !!
