The generator consists of the stator, rotor, cover, bearing and air-to-water
cooler. The stationary armature is attached to and supported by generator
base. The rotor is supported by the bearings. Air-to-water coolers are mounted
above the stator. The cooling system is completely enclosed to prevent
exposure to dust and moisture.
HISTORY:
Delivered 2009, currently stored indoors and secured, Turbine & Generator
completely sealed. Silica gel is inserted in the Turbine & Generator and
regularly replaced. Equipped with electronic monitoring sensors for humidity &
temperature with criteria from Toshiba for storage, monitoring report
generated monthly, inspection of unit every (2) weeks, thorough inspections
were done every (6) months until 2012, then yearly, inspection protocols.
