Abstract

One-dimensional transient thermal model of the lengthy HTS conductor using thermoresistive effect to measure the level of cryogenic liquid was created. Resulting model made it possible to determine the distribution of pace-tures along the length of the HTS conductor and other characteristics. The comparing-of calculated and experimental data obtained at an atmospheric dewar with liquid nitrogen was carried out.
