High voltage compact generators

ABB's generators cover 1 - 8 MVA compact 4, 6, 8 and 10-pole generators at voltages of 3.3 - 13.8 kV. This product family offers the same high reliability and low cost of ownership as our proven high power generators. The generator series incorporates a number of professional features that meet the specific needs of the mid-range market segment for both engine and turbine applications.

Save time, cut costs and power through demanding loads

These flexible high performance generators are ideal for both continuous and stand-by operation and they are built to cope with changing and non-linear loads. They feature a powerful and most reliable independent PMG excitation as standard, offering excellent short-circuit, overload and motor starting capabilities. The innovative built-in PMG also enables easy access for bearing servicing. The 500-630 frame size open air cooled generators utilize a rigid salient pole rotor construction for reliable operation under the most demanding load conditions.


The mid-range family is designed to help save installation time and cost. Their high degree of integration makes the generators compact and easy to erect, with a built-in brushless exciter and the internal high performance PMG. To avoid large external terminal boxes, the cable connections are integrated into the frame-top terminal space. There is ample room for easy connection of the main and auxiliary cables, and to accommodate the necessary transformers as well as the analog or digital AVR.
