Investigation of AC Loss in HTS Cross-Conductor Cables for Electrical Power Transmission

open access: yes, 2019
This paper presents the alternating current (ac) loss analysis on high-temperature superconductor (HTS) cross-conductor (CroCo) cables, in order to evaluate whether they can be utilized for electrical power transmission.

Theoretical analysis of AC transport current loss in bulk Y-123 [PDF]

open access: yes
The AC-current loss in a quench melt growth (QMG)-processed Y-123 bulk superconductor was found to fit well with the Norris’s formula for a superconductor with an ellipsoidal cross-section based on the Bean’s model, in spite of a rectangular cross ...

AC current loss of a meander-shaped QMG current limiting device [PDF]

open access: yes
The AC current loss of a meander-shaped QMG current limiting device was measured. Although the frequency was changed in the range of 35–200 Hz, an obvious frequency dependence of the AC current loss was not observed.

The influence of unsymmetrical AC power input to the core loss of a single phase transformer

open access: yes, 2007
This final year project describes about the influence of unsymmetrical AC power input to the core loss of a single phase transformer. The unsymmetrical ac voltage is generated using unidirectional (half wave) ac voltage controller circuit.

Numerical Simulation on AC Loss in REBCO Stacks and Coils Carrying Non-Sinusoidal Currents

open access: yes
AC loss is a critical issue for high-temperature superconducting (HTS) applications. Earlier studies have focused on ac loss in HTS conductors carrying sinusoidal currents.

AC losses in MgB2 superconductors

open access: yes, 2007
This Master thesis studies losses in superconductors. Losses arise when the superconductor carries alternating current or is placed in an alternating magnetic field. As most power applications involve at least one of the two, loss mechanisms and magnitudes are important when examining the possibility of making superconductor systems competitive to ...
