HTSC transformer is a highly promising long-term innovation for the electric traction system. Present R&D and prototypes promise high (50 Hz systems) to very high (16,7 Hz systems) energy efficiency effects. Remaining technological uncertainties are medium. According to manufacturers profitability is high enough to ensure reasonably fast payback of high initial costs. Maintenance and downtime costs are difficult to predict. Despite these uncertainties, HTSC transformers appear as a long-term option deserving intensive R&D efforts and further co-operation between railways and manufacturers. |
