Superconducting transformers with fault current limiting capability based on high temperature superconducting coated conductors are promising devices which have several benefits compared to conventional power transformers: 1) no oil is used (environmentally friendly), 2) weight and volume are reduced by 30 to 40%, 3) better efficiency (upgrade of 0.5%), 4) longer expected lifetime, 5) reduced impedance, 6) new functionality useful for smart grid (can act as a fault current limiter) and 7) possibility to overload the transformer for long period without degradation, at the expense of a reduced efficiency.

与传统的电力变压器相比，基于高温超导涂层导体的具有故障限流能力的超导变压器具有以下几个优点：1)不用油（环保），2)重量和体积减少30%至40%，3)效率更高（升级0.5%），4)预期寿命更长，5)阻抗降低，6)智能电网有用的新功能（可作为故障限流器）和7)可能使变压器长期过载而不退化，以降低效率为代价。
