About our ABB service
ABB is one of the dominant Tier-1 OEMs for industrial synchronous generators in Latin America, with a large installed fleet across utility power plants, cogeneration facilities, oil & gas, mining and heavy manufacturing. As an independent multi-OEM workshop, TEMISA Power Gen services ABB generators throughout their full life cycle — beyond OEM warranty — under IEC 60034, IEEE 115, IEEE 421 and the EASA AR100 standard, with IEEE 56 as reference guide.
Workshop capabilities
What we deliver on ABB
- Salient-pole and cylindrical rotor rewinding (4 to 80+ poles), pole rebuilding, field coil reinsulation
- Stator winding rewind under EASA AR100 with VPI vacuum-pressure impregnation Class F or H
- UNITROL brushless excitation diagnosis and field replacement of AVR boards + components
- ELCID core test (CIGRE TB 257) before any rewind work — mandatory under EASA AR100
- Pole-to-pole voltage drop test (documented protocol, each pole compared against the average and the asset history) for inter-turn short detection in field coils
- Dielectric testing package (Megger + IP + Tan Delta + DP + Hipot)
- Dynamic balancing G2.5 under ISO 21940 in our 60-ton workshop crane facility
- Commissioning with IEEE 115 acceptance tests for grid interconnection
Applications
Industries we serve on ABB
Utility power generation (CFE)
Base-load ABB synchronous generators in CFE-owned thermal and combined-cycle plants requiring full overhaul and commissioning compliance.
Sugar mill cogeneration
ABB AMS-series generators 5-25 MVA driving back-pressure steam turbines in sugar industry — seasonal high-cycle operation requires pre-harvest diagnostic and major overhaul during off-season.
Oil & gas + refineries
ABB synchronous + induction generators in refinery balance-of-plant and gas processing — API 670 vibration monitoring electrical testing.
Mining + heavy industry
ABB SM/SP-series generators 10-80 MVA in mining facilities and cement plants — abrasive environment requires specialized maintenance program.
Frequently asked questions
How does TEMISA Power Gen service ABB equipment?
TEMISA Power Gen is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
What ABB generator lines do you service?
We service the full ABB synchronous generator range: AMS series (cylindrical rotor, 1-50 MVA), SM series (salient-pole, 1-150 MVA), SP series (large salient-pole). For excitation: UNITROL 1000/1010/5000/6000 series. For AVR: digital and analog Vista-class controllers. Our team has trained on ABB documentation including Generator Service Manual (GSM) standardized format.
How long does an ABB major overhaul typically take?
Lead time depends on the diagnosis and scope (for example, whether a stator rewind is needed). We provide a formal schedule on quotation review including critical-path activities and procurement timeline for any imported parts.
Can you fabricate ABB spare parts locally when OEM lead time is 32+ weeks?
Yes — within scope. For stator windings, rotor field coils, brush gear, AVR boards and excitation components, we manufacture compliant replacements in our Tlajomulco workshop in 8-14 weeks (vs 32-52 weeks OEM lead time from Sweden/India). All locally-fabricated parts are tested under EASA AR100 + with traceability ISO 9001:2015. For specialized OEM-proprietary components we coordinate procurement on your behalf.
