Wind Turbine Generator Service — Vestas
Do you operate Vestas wind turbines? TEMISA Power Gen services the ELECTRICAL GENERATOR inside the nacelle — not the turbine, blades or gearbox. Rewind, repair, DFIG/PMG diagnostics and electrical testing, on-site and in-shop, under EASA AR100. Independent and multi-OEM.
Important: TEMISA does not repair the Vestas turbine, blades or gearbox. We specialize in the electrical generator inside the nacelle — independent shop with no affiliation to Vestas; the brand name is used only to identify the equipment. See the full scope in wind turbine generator repair in Mexico.
TEMISA Power Gen provides independent service to the ELECTRICAL GENERATOR inside Vestas wind turbines. We rewind, repair and diagnose the generator — on-site and in our workshop — under EASA AR100, IEEE and ISO standards, with coordinated response. We do not service the blades, gearbox or nacelle structure: we specialize in the electrical machine.
Generator topology
Doubly-fed induction generator (DFIG, wound rotor with slip rings) on variable-speed platforms, and permanent-magnet generator (PMG) on the newer platforms.
The challenge in the generator
On the Vestas DFIG, the slip rings, brush gear and the wound-rotor insulation exposed to thermal cycling and humidity are the critical point. Partial-discharge diagnostics and a Class F/H rewind with VPI restore reliability.
In Mexico
Vestas has one of the largest installed bases in Mexico, present across the main wind regions. The sheer fleet size makes fast, independent generator service decisive for park availability.
