Generator Service in Turbomachinery Trains
We service the generator and its excitation in turbine-generator trains: rotor balancing, laser alignment to the turbine, vibration analysis and electrical tests. Turbines are handled by strategic partners.
Workshop capabilities
Generator service in the train
We work on the generator side of the train and plan each intervention around the plant outage window, coordinating with the partners who service the turbine.
- Dynamic balancing of the generator rotor, G2.5 class under ISO 21940, in single and dual-plane configurations
- Laser alignment of the generator to the turbine with thermal growth compensation (API 686)
- Vibration analysis FFT under ISO 10816 measured at the generator, with cascade plots and order analysis
- Generator bearing diagnosis with sensor verification under API 670
- Electrical tests on the generator and excitation system (IEEE 43, IEEE 95, IEEE 115, IEC 60270)
- Rewinding, repair and commissioning of the generator, on site and in our shop
Equipment types
Generators we service by drive type
Steam turbine generators
Generators driven by back-pressure, condensing and extraction steam turbines in cogeneration, refineries and petrochemical plants.
Gas turbine generators
Generators driven by aero-derivative and heavy-duty gas turbines in power generation and industrial plants.
Combined-cycle trains
Generators of gas and steam turbine trains in combined-cycle plants.
Scope limit
We are not an EPC contractor and do not service turbines, compressors, pumps or prime movers. On the turbine side we coordinate with strategic partners.
Sectors served
Industrial sectors with turbine-driven generators
Sugar mill cogeneration
Synchronous generators driven by back-pressure turbines, supplying the mill and exporting power to the grid.
Oil refineries + petrochemical
Generators driven by process steam turbines and gas turbines.
Combined-cycle power plants
Generators of gas + steam turbine trains in combined-cycle configuration.
Industrial process plants
Cement, steel, paper, chemical — generators in 24/7 continuous service with limited shutdown windows.
Frequently asked questions
Do you service steam or gas turbines?
No. TEMISA Power Gen services the generator and its excitation system. We are not an EPC contractor and do not service turbines or prime movers; on the turbine side we coordinate with strategic partners, so the client keeps a single contact for the electrical side of the train.
What is dynamic balancing G2.5 and when is it required on a generator rotor?
ISO 21940 G2.5 is a balance quality grade that limits residual unbalance to 2.5 mm/s at the rotor center of mass. On a generator rotor it is required after rewinding, retaining-ring work, machining or thermal events that distort the rotor.
Which manufacturers do you work with?
TEMISA is a non-exclusive authorized service representative for TDPS generators in Mexico (agreement dated 12 January 2026, signed 19 February 2026). Supply, parts and warranty terms are confirmed in writing for each project. TEMISA Power Gen is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
