UNICITER® Brushless Excitation Advantages
No carbon dust contamination! No wear (no electrical no mechanical contacts) No consumable parts (brushes) No circuit breaker and no field breaker (in case of static exciter)
Results in… Reduced maintenance (from each 3/4 months to 5/6 5/ 6 year) Reduced outage time Reduced costs for replacement parts
