Guideline on Testing of Turbo and Hydro Generators

The maintenance, inspection and testing of large generators remains one of the most significant costs of asset ownership for electricity generation companies worldwide. Competitive reforms in electricity utility ownership and change in operational practices have imposed significant cost pressures. As a result, in many countries these processes forced utilities to reduce maintenance and inspection frequency and accept greater operating risk, albeit through managed risk assessment and mitigation programs. There is both factual and anecdotal evidence that in some instances the risk envelope is being stretched quite significantly compared to previous practice.
