Reconditioning pulp and paper mill generators for reliable service

This paper presents the latest generator "reconditioning" techniques, important to maintaining high reliability for this specialized equipment. These techniques involve preventive and predictive maintenance testing and inspections that, if done consistently, will ensure reliable operation of this class of generators. Also included are three brief case histories that describe activities falling in the category of "major" reconditioning. The focus is on generators rated in the 10 MW to 100 MW range, manufactured in the 1950\´s and 1960\´s. Many of these machines are at or near the end of their life, and they should be reconditioned to provide additional extended service
