Short-circuit protection for electrical dc and ac networks of ships and offshore installations

Short-circuit current protection system for electric DC and AC networks of ships and offshore installations, A short circuit current protection system (40) for electric DC and AC networks of ships and offshore installations a high-temperature superconductor (HTS) current limiter (1) through which the short-circuit current flows, - A cryostat for receiving and cooling the HTS current limiter (1) and - A refrigerator for the recondensation of existing in the cryostat gaseous refrigerant. According to the invention, the short-circuit current protection system is suitable for ships and / or offshore platforms with regard to function and structure, and has means for electrical, procedural and mechanical integration into the ships and offshore installations.
