IPS provides worldwide service, repair, and rewinds for large utility turbine generators. We specialize in multipole and turbo generators up to 150 MW, backed by our North American service, engineering, and remanufacturing resources.
We offer a competitive alternative to OEM service and repair, rebuilding to OEM specifications or above with shorter lead times. Our turbine generator experts have decades of experience with your equipment, backed by OEM-level investments in engineering and manufacturing.
IPS always has boots on the ground fast, particularly in emergencies. We also work effectively with plant reliability engineers and maintenance supervisors during planned outages.
We know how OEMs design to prevent problems, such as bearing wear and rotor cooling, and how to resolve them in the field. IPS incorporates best practices from the leading turbine generator OEMs into everything we do.
IPS partners with turbine specialists to provide turnkey service and repair solutions. If we’re working within a planned outage, we recommend comprehensive testing to establish a baseline and guide service recommendations.
Our field services for salient pole and turbine generators include:
IPS repairs and overhauls large utility turbine generator rotors, stators, and exciters. We build temporary clean rooms in situ to prevent airborne contamination and provide climate control during rewinds.
Our repairs for generator stators include:
Our repairs for generator rotors include:
IPS also provides full rewinds for exciters. Our technicians have the equipment to keep more work on-site, such as heat-treating retaining rings and complex machining.
Our large utility generator experts lead the IPS response to your service and repair requirements. We’ve worked on various multipole and turbo generators from the industry’s leading OEMs:
IPS redesigns and retrofits legacy generators, increasing insulation class or redesigning for higher kW output. When blueprints are unavailable, we disassemble old generators, reverse engineer, then design, manufacture, and install new components.
Our B-stage hard coil rewinds combine the advantage of more advanced materials and custom manufacturing in limited volumes. IPS engineers and builds coils to spec, shipping semi-treated B-stage coils for curing on-site.
Custom Equipment (CE) offers engineering, manufacturing, and fabrication for customized power distribution solutions. This includes motor control centers, medium- and low-voltage switchgear, transformers, and substations.
IPS packages VFDs for harsh-duty applications. We couple units with permanent magnet motors and driven equipment — fans, pumps, and compressors.
Our VFD recommendations typically produce energy savings that pay for the equipment within a year. IPS has massive VFD inventories across North America, plus peripheral options for specific applications:
IPS handles new and legacy transformers, with on-site service and repair for generator step-up transformers, rated up to 345 kV and exceeding 1,000 MVA.
We redesign generators for increased power density and energy efficiency, including equipment no longer supported by the OEM and without drawings.
Our subject matter experts teach customers how to operate and maintain electrical and mechanical equipment for improved safety, reliability, and efficiency.
