HTS: strain
Maximum strain in HTS is similar to that of LTS
HTS is in intimate contact with structure (as opposed as Cable-In-Conduit-Conductor, CICC)
- Steels have E ~ 200 GPa
- 0.2% strain results in only 400 MPa, as opposed to assumed stress in structure (I.e., due to strain limitations, stress in structure could be reduced by a factor of 2!)
A possible solution is to manufacture HTS so that it is in compression (-0.2% strain) when cold and unloaded
- With 800 MPa in the structure, strain in HTS is 0.2%
