Generator Services

Houghton International specialises in generator repairs, servicing and monitoring. We expertly maintain and upgrade power generation equipment globally, offering a variety of in situ options for onsite maintenance and rewind.

We offer mechanical and electrical generator repairs for a broad selection of generators including induction generators, slip ring generators, salient pole synchronous generators, steam or combustion turbines and generators for industrial application, up to 50MW or 100MW for turbo-alternators.

With over 30 years’ specialist engineering experience, in-house coil manufacture facilities and a large machine repair shop with up to 40 tonne craneage, we support customers globally in the repair, servicing, and rewind of a range of power generation systems.

Our site services include –

  • In situ inspection, testing and fault diagnostics including air gap checks and Partial Discharge testing
  • Equipment removal
  • Generator installation and commissioning
  • Preventive and predictive maintenance, including infrared thermal imaging, vibration analysis, oil analysis, borescope inspections, laser shaft alignment, field balancing and a range of electrical testing, including partial discharge testing and analysis
  • In situ field and stator rewinds – using our HiFLEX™ HV coils for improved performance
  • Field machining

We offer planned maintenance during shutdowns and 24/7 emergency outage support, with absolute control over quality and lead-times.

We have obtained experience from a diverse number of projects, from a complete rewind of a hydro generator in-situ in Norway to supplying a complete set of 256 13,800V HiFLEX™ high voltage (HV) coils for a 6.8MW generator on site rewind in British Columbia, Canada. Alternator and generator overhauls and rewinds have also been carried out in house for a range of UK power producers.

Independent of the large OEMs, we work flexibly with customers to solve problems and improve generator performance in a safe and cost-effective way. In addition to sourcing OEM approved parts and spares we also have reverse engineering and 3D design capabilities to address obsolescence and can support the commissioning and decommissioning of equipment on site as required.
