The special feature of superconductors, which is the total lack of electrical resistance under certain strictly defined conditions, means the elimination of energy losses for the release of heat during current flow, and thus a reduction in the energy consumption of devices made of superconductors or an increase in their efficiency and performance while maintaining a certain level of power.
A rapid increase of the resistance in superconducting materials when the critical current value is exceeded, allows them to be used to build short-circuit current limiters in electromagnetic networks. They constitute an excellent protection against the dangers resulting from high-current short circuits. Superconducting current limiters do not affect the flow of current during normal operation of the network, and after being tripped they immediately return to operation without any additional actions.
One of the properties of superconductors is their diamagnetism. This feature allows to build more efficient electromagnets. The magnetic field obtained by using superconducting material is stronger, while superconducting coils allow to reduce energy losses.
SC systems assembly
MgB2 is a intermetallic superconductor classified as a medium temperature superconductor. Despite being a intermetallic superconductor, it can be manufactured in wire form and can be used in most applications at higher temperatures, thus enable conduction cooling for large magnet coils in the 4-30K range
Niobium-tin superconductors (Nb3Sn)are known for their great performance in high magnetic fields. It is a great alternative to NbTi when magnetic fields above 10 tesla are needed. Above 10 tesla, Nb3Sn is less expensive than NbTi on a $/kA-m basis.
SMES - superconducting energy storage. Is an innovative application of superconducting technology to store energy in a magnetic field.
