Adding Value

At every step within each procedure, Action Technology seeks ways to extend the life of a generator by reducing even the small outage risks.

Action Technology understands modernization and life extension of the generator is the job – not simply repairing and maintaining. Action Technology is skilled in problem-solving through innovative solutions. Whatever the issue on a generator (adequate design, a flaw in manufacturing, loose windings, thermal aging, load cycling, partial discharges, contamination, questionable test results, or something else) Action Technology has people ready to help develop a path forward. Every Action Technology crew member understands the reasoning behind the careful, detailed rewind management and methodology that assures a smooth-running generator.
