1. Introduction
AC loss is one of the most important characteristics ofsuperconducting power transmission cables for theirintroduction into power grid.㻌 Cables are composed of several
tens of coated conductors, and there might be a damaged
coated conductor among them; existence of a degraded section
along a coated conductor may be more possible. Damaged
coated conductors can cause distortion to magnetic fields andreduced capability of transporting power to cables, whichconsequently increase the entire AC losses. This paper presents
a detailed analysis on the influence of damaged coatedconductors on AC losses of superconducting powertransmission cables. First, AC losses of cables with/without
damaged coated conductors are calculated. The influence ofdamaged coated conductors is discussed. Second, the influenceof location of damaged coated conductors is analyzed.
Corresponding numerical results are presented and discussed.

conductors located in different layers. Take 4-layer cable for
instance, “1st layer damaged” means the damaged coatedconductor is located in the 1st layer counting from inner layer.
It is obtained that the location of damaged coated conductors
has a subtle influence on AC loss comparing to the damage
itself. Specifically, cables are more affected while the damaged
coated conductor is located in the outer middle layer.
3. Conclusion
Damaged coated conductors have a significant influence on
AC losses of superconducting power transmission cables. The
influence weakens as the number of layers increases. Locationof damage affects AC loss slightly.
This work is supported by the New Energy and Industrial
Technology Development Organization in M-PACC project.

2. Numerical results and analyses
All the AC losses are calculated with a numerical model
employing 1D FEM [1]. As shown in Fig. 1, cables areconstructed using 4 mm wide coated conductors with 2ȝm
superconductor-thickness. The gaps between adjacent coatedconductors are 0.36 mm wide. Ic of each coated conductor is
100 A. Damaged coated conductors do not carry any current
and cables before and after damage carry the same transport
current It. Detailed properties of cables are listed in Table 1.

Fig. 2 Normalized AC losses of cables with/without damaged
coated conductors and with reduced critical current.

The numerical results presented in Fig. 2 show that AC
losses increase in all cables after damage. Mono-layer cable ismost affected by the damage, whereas 6-layer cable is slightly
influenced. Cables not damaged but have the same Ic asdamaged ones, which evenly distributes among all the coatedconductors, are also presented in Fig. 2. The AC losses of thesecables are higher than the undamaged ones, however muchsmaller than the damaged ones. This proves that damaged
coated conductors have a significant influence on AC loss.
