Hydroelectric Power — Generator Repair Services
We specialize in single-source solutions for hydroelectric generators — repair services, field services and engineering, and distribution. Our North American network means we can deliver more experience and resources than local repair shops, with response times and cost advantages that larger, multi-national service providers can’t match.
Service and repair for all hydro generators
IPS field services technicians use a full spectrum of electrical tests:
We also provide engineering evaluations with uprate and design services, for more power and reliability in the same footprint. Below is a sample of our extensive hydro experience. For details on these or other IPS hydro projects, talk to your regional IPS sales representative.
Specializing in:
In-shop repairs for big jobs
We have the experience you need with large-scale projects, plus the lift capacity and equipment. IPS repair technicians manufacture new stator cores, rebabbit bearings and repair exciters.
We also provide complete machining services, with IPS Portland taking the lead on machining large hydro shafts and brake rings. We can remove old sleeves, manufacture new sleeves, and then split and weld them into place.
We also machine and polish bearing fits, and clean, detail and re-cut flange faces. Like every IPS job, our in-shop repairs meet OEM spec or better, and we document and validate everything we do.
Hydro generator rewind (45 MW / 11.5 KV / 400 RPM / 13′ dia.)
Each coil weighed over 100 lbs.
On-site hydro generator rewind (10 MW / 6.9 kV / 171 RPM) using IntegraSeal B-stage stator coils
Hydroelectric field services
IPS coast-to-coast locations give you local responsiveness, backed by massive regional and national resources. Our dedicated field service technicians provide IEEE-approved electrical tests, cryogenic cleaning, vibration analysis, and other predictive and preventive services.
We also offer complete generator disassembly and repair, on-site stator and rotor rewinds, and repair and replacement for bearings, shafts and exciters.
Engineering – uprate and design services
If your operators use older hydro generator designs, offering limited power production or longer supported by the OEM, IPS can help. We optimize generators and components to increase power output and reliability in the same footprint.
If blueprints are no longer available, we can disassemble old generators, reverse engineer and then design, manufacture and install new components.
