GE Power Conversion Generators 2,500 to 80,000 kVA Up to 22,000 Volts
GE has been setting the standard in generator manufacturing for over 130 years.
GE created and implemented the first fundamentals of large-scale electrical generation. Today we continue to deliver innovative power generation solutions to the world. We continue to innovate with product quality Generators are designed and manufactured to operate efficiently and reliably in challenging applications and severe environments where ease of maintenance is critical.
Generator Products 4-Pole Synchronous Gas and Steam Turbine Applications Our range of 4-pole generators provide a reliable product which is based on a modular construction concept utilizing the latest design and manufacturing techniques. All generators include Vacuum Pressure Impregnation (VPI) insulation systems (for both the stator and rotor components) and a unique vent stator technology for maximum heat dissipation.

Generator Products Reciprocating Engine Driven (Delta) Diesel and Gas Reciprocating Engine Applications Wind Turbine Applications This design has the stator mounted into a base-frame with pedestal bearings to support the rotor. These are used in many applications from Prime and Emergency Power to Marine Power. Although these machines employ the same insulation systems as other generators, they tend to be more specifically designed for the application or project.

Rotors Laminated Pole Bolted Tip Solid Pole ~ ~ ~ ~ ~ ~ Class H winding technology ~ Improved thermal performance ~ Individual bladed fan designs Laminated cruciform assembly Wire-on-Edge field windings Coils wound directly on poles Cooling vee-block designs Advanced ventilation and fan designs This rotor has a laminated cruciform assembly and a wire-on-edge field winding.
Rotors Integral Tip Solid Pole The pole tips or shoes on this rotor are machined from the single rotor forging. All other features are the same as the bolted tip rotor. Solid poles hold a strip-on-edge field winding. These types of rotors are used in special 60 Hz applications or otherwise specified by customers requiring maximum durability.
Stators Two Layer Lap Winding ~ ~ ~ ~ ~ Low-loss lamination grade No core-pack welding Individual slot wedging Thermal vent technology Global VPI with rotate cure The stator core assembly consists of varnished laminations of cold-rolled low-loss silicon steel, clamped between compression plates. The laminations are supplied in the finally annealed condition, and are insulated to reduce eddy current losses. The core is built around a central mandrel, to enhance the bore profile.
Vacuum Pressure Impregnation (VPI) Void free insulation is vital for the life of medium and high voltage insulation systems. The stator is heated in an oven to dry out any moisture. Then it is placed into a pressure vessel where the lid is vacuum sealed. Then resin, at varying temperature, is pumped into the chamber to fill all voids on the stator. After a period of time, dry air is pumped into the top of the vessel creating a “pressure blanket” over the resin, “pushing” it into all remaining voids.

Analysis Tools Finite Element Terminal Box Integrity Modern analysis tools such as finite elements make predictions regarding performance more accurate. Before integrating the generator with an engine, we calculate all the natural frequencies of the machine in order to avoid exciting them. Through a particularly advanced mathematical simulation we can calculate the effects of an explosion in a terminal box due to an electrical fault.
Training and Service Training & Service Generator Controls Global Service Capability The GEPC RVD Mk III system uses a Programmable Logic Controller (PLC) to perform all the control functions and fire a power stack for the excitation. These are generally part of a “turnkey” type system where many other controls functions are being supplied by GE. These systems are most common in large, utility-type generators.
