Shielding of Unconventional High Surge Impedance Loading Transmission Lines

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper focuses on determining the optimal location and number of shield wires for a novel‐designed unconventional high surge impedance loading line. This line has a much lower surge impedance than conventional lines, raising key questions on the location of shield wires to meet an acceptable shielding failure rate (SFFOR).

Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...
