INDUSTRIAL GENERATOR SERVICES

Illinois Electric Works Generator Services specializes in the testing, inspection, and repair of all turbine generators.

SOME OF THE SERVICES WE OFFER

Power Generation

Our industrial generator services include thorough inspections and high-voltage testing. We’re determined to locate your problem’s source so that your generator can operate at maximum performance. 

Generator Stator Repairs: Tightening of end winding, Partial and full wedging, Core iron, Full or partial rewind, Leak detection and repair etc.

Field Repairs: Bore copper removal and replacement, collector ring replacement, hydrogen seal replacement, retaining ring replacement, main lead replacement, single coil rewind, full field rewind, etc.

Lead Box Repairs: Stand-off bushings, high voltage bushings, CT replacement, etc.

We offer three types of Generator Integrity Tests, depending on the degree of testing you require. Once we’ve conducted the appropriate test, we’ll determine the right industrial generator repair to get the job done.
