In the system is called cooling module. The function of cooling module include cooling lube oil in turbine gas, as a water atomazing cooler, as turf buffer, and cooling in H2 generator. Cooling module system is very digital in the generation of damage to the motor can cause heat exchange is not optimal. Cooling module system there is a fan motor drive called the 88FC motor. On major inspections the motor is subjected to load testing prior to overhaul, loading on the motor around at 41,73%. No-load testing on the 88FC motor before and after the overhaul that on motor88FC after the reduction of vibration down and no load obtained with identical motor was the same result. After reassembling the coupling with fan cooling in the test load current has increased to 75% it causes a problem on fan cooling / fan.} }
