There are three techniques for measuring AC losses. Progress on the calorimeter method, the most desirable measurement, is described on the AC losses page. These devices will perform as fast subcycle breakers when installed at strategic locations in the transmission and distribution systems. Electrical tests of such coils are described on the current controller page. The CLTF is designed to accommodate a variety of HTS lead configurations and materials.
Refrigeration is provided by cryocoolers, eliminating the handling of liquid cryogens.
An update on the status of this program is given on the current leads page. Progress in this activity is given on the magnetic refrigeration page.
