Effect of winding pitches on screening current induced field of CORC cables

Key Points

• Induced field variations depend on the winding pitch of CORC cables, and the changes can influence electromagnetic shielding performance.
• Measurements indicate that changes in winding pitch can lead to significant differences in screening current effects, revealing up to a 30% performance variability.
• Assessment using electromagnetic modeling of CORC cable designs demonstrates the interplay between winding configuration and shielding effectiveness.
• Findings support the notion that optimizing winding pitches can enhance screening performance, highlighting potential benefits for cable design.
