Power Generation
The turbine generator is at the heart of a power generation plant. It is critical therefore that this large, expensive machinery operates reliably and with as little downtime and maintenance as possible.
The excitation current for the generator is transferred to steel collector rings by means of a sliding electrical contact using carbon brushes. The sliding contact speeds on these turbo-alternators are some of the highest for any carbon brush application in industry, with speeds up to 16,000 feet per minute or 81 meters per second.
Morgan’s National electrical carbon grade 634 is a world renowned graphite grade. It is the preferred grade specified by turbine generator original equipment manufacturers and power plants around the globe. The low friction, consistent contact drop and good brush life make grade 634 a superior product. More importantly, grade 634 is gentle to collector rings to minimise the need for collector ring maintenance.
