TRACK GP 9W4168 - Caterpillar

give nameplate rated amperes but because of the voltage reduction the available kW and KVA will be 92% of the nameplate rating.If the wire on the 139V tap is moved to the 120V tap, the generator will operate as a 208-416 unit. The generator can give nameplate rated amperes but because of the voltage reduction the available kW and KVA will be 87% of the nameplate rating. Make a mark (show new location) on the nameplate of the generator when saturable reactor taps are changed from the original position.

Saturable reactor (A) has the common tap connected to DC controlled reactor (C). The 120V tap (127V tap on the D375 2400V generator) is connected to the phase windings of (T2) through regulator terminal (10). The generator neutral (T0) is connected to the regulator through regulator terminal (2). For more information on the exact location of the phase winding tap for the regulator reference lead make reference to REWIND INFORMATION.This arrangement gives no more than 139V at the saturable reactor. This is the highest voltage in the regulator compartment.
A 2400 volt generator must not be operated, even on open circuit, without a good ground connection made to (T0).
