Based on previous studies, the AC loss characteristics of each layer in a high-temperature superconducting cable were experimentally investigated. A model was developed to estimate the AC loss by considering the maximum and minimum values of the loss, showing good agreement with experimental data. This model allows for estimating AC losses and designing the minimum AC loss load for a superconducting cable, specifically a three-layer twisted HTS cable.
In a previous study, the AC loss characteristics of each layer of a high-temperature superconducting (HTS) AC cable were experimentally investigated (Ogawa et al., 2020; Ogawa et al., 2017; Ogawa et al., 2019). Based on these data, we modeled the AC loss in a superconducting cable by considering the maxi-mum and minimum values of the loss. A comparison between this model and the experimental data showed good agreement. Hence, it is possible to estimate AC loss under electromagnetic conditions in a high-temperature superconducting cable. This model makes it possible to determine the losses of each layer in the superconducting cable and to design the minimum AC loss load of the superconducting cable. This model estimates the AC losses of a three-layer twisted HTS cable.
