This recently developed engineering approach combines the cutting edge in generator technology with the interfaces of legacy generator types while ideally catering to the operator's economic interests. The focus is on integrating state-of-the-art active parts as used in today's newly built units to engineer tailored replacement machines that will take over from the original machines within a foreseeable time frame.
The replacement machines are designed to mate with all relevant interfaces (i.e. shaft centerline height, foundations, etc.) of the legacy unit and to facilitate quick exchange.
The footprint approach can be applied to nearly all generators, irrespective of the model and type of cooling, and for all conventional designs on the 50-Hz and 60-Hz markets, for voltages of 6.3 kV, 10.5 kV or 13.0 kV.
