Generator Repair & Services

MD&A provides comprehensive refurbishment & repair of large utility turbine generator stators and fields, including high voltage bushing refurbishment and the complete rewinding of inner liquid-cooled generators.

Our turbine-generator repair facility centrally located in St. Louis, MO can accommodate generator field rewinds of any capacity, including large 4-pole nuclear units.  Our generator experts can also perform a stator rewind on-site.

Through years of power generation industry experience, our generator repair specialists conduct full-scope electrical testing, visual inspections, and specialty tests as per customer requirements.

Our generator in-situ inspection robot, MD&A’s Air Gap-Bot, can perform full generator inspections without removing the field, saving time on the outage.

We invest heavily in the development of people, procedures, and principle which facilitate improvements in design, reliability, and performance.  Our generator experts designed many solutions to numerous aging fleet issues; for example, 7FH2 generator spring migration repair and dusting on 7FH2 & 324 stator end winding systems.
