Generators

We offer mechanical and electrical repairs to a broad range of generators including induction generators, slip ring generators, synchronous – salient pole 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, maintenance 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 shut downs and 24/7 emergency outage support, with absolute control over quality and lead-times.

We have obtained experience from a diverse range of projects, from a complete rewind of a hydro generator in-situ in Norway to supplying a complete set of 256 13,800 volt 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 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.
