10.1.4 Slip rings
Electrical power is transmitted
from the yawing nacelle to the
stationary mast via slip rings.
The carbon brushes used to
accomplish this are designed to
last the life of the generator,
however periodic checks for
unusual wear or loss of contact
material is recommended.
Unscrew the two black
cylindrical screw caps (see fig.
10.1.4) and remove the carbon
brushes to inspect. Worn or
damaged carbon brushes must
be replaced. Carbon brushes should be replaced in pairs (replacement brushes are
sold in pairs and include new screw caps). Inspect the cap O-ring seals for damage
prior to reinstallation.
Use caution when unscrewing the two plastic screw caps. The
carbon brushes are spring loaded and can rapidly exit the unit,
resulting in loss of the brush assembly.
10.1.5 Corrosion protection
The generator housing and wind vane are constructed of a corrosion resistant, marine
grade aluminum alloy that is also powder coated for additional corrosion protection.
Inspect this powder coating and touch up any damaged areas noted with a suitable
lacquer paint.
All steel parts (e.g. ball bearings, shafts, axles and bolts) are stainless steel and need
no special corrosion protection.
10.1.6 Mast
Check the mast or support structure for damage, corrosion, loose hardware, etc.
Refer to the appropriate mast or support installation guides.
10.1.7 Electrical system
Electrical system inspections must be performed by qualified personnel. Before
performing any inspection, verify that all lines are safe and that the wind generator is
secured and cannot start unexpectedly.
Check all electrical connections, making sure that they are tight and free from
corrosion. Pay particular attention to battery terminals, which are especially prone to
corrosion. Clean all terminals of corrosion and coat with a suitable battery terminal
grease to prevent future corrosion.
