Life Evaluation of Strategic Generator and Condenser Assets

Ageing of electrical machines is associated with the thermal life and fatigue of the active components. There are many strategic machines in power systems that have surpassed normal design life criteria, reasonably and initially proposed as 40 years. Some applications are certainly more stressful than others, the nature of the application, high speed steam or gas turbine, low speed waterwheel, synchronous condenser has effect on both fatigue and thermal ageing.
