ABSTRACT The long‐term hydrophobic stability of silicone rubber (SiR) insulators is essential for their reliability in high‐voltage direct current (HVDC) applications. This study investigates the effect of nano‐silica fillers with varying specific surface areas (SSA = 120, 200 and 300 m2/g) and different concentrations of alumina trihydrate (ATH ...

ABSTRACT The development of autonomous electric vehicles (AEVs) represents the convergence of two simultaneous automotive revolutions: electric vehicles (EVs) and autonomous vehicles (AVs). AVs require sensors, decision‐making systems and actuation systems to achieve autonomous driving, whereas EVs require intelligent management and real‐time ...

Busbar Fault Direction Identification Using Sequences of Displacement Vectors
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

Standard and proposed non‐standard OCR characteristics. ABSTRACT This study introduces an advanced adaptive protection approach for AC power systems, designed to address key limitations in current clustering‐based relay coordination methods. Using K‐means, hierarchical, and spectral clustering techniques, the proposed scheme classifies grid operating ...

In high‐speed maglev trains, the active guidance system is responsible for centring the vehicle relative to the track, a function that becomes critical under centrifugal forces, crosswinds, and track irregularities. To address the limitations of existing control methods in multi‐disturbance environments, this paper proposes a gap‐loop active ...

This paper proposes the split‐station architecture, which uses high‐temperature superconducting (HTS) cables as ‘virtual bus extensions’ to decouple transformation from distribution in medium‐voltage systems. PYPOWER simulations validated against Project Hydra 13.8 kV specifications demonstrate that a 3‐km HTS link reduces voltage drop by 46 ...
