Intensification of Electric Field Stresses in Field Aged 380-kV Composite Insulators Due to Loss of Hydrophobicity

IEEE Access
Polymer based composite high voltage insulators (HVIs) due to their hydrophobic surfaces have consistently outperformed the traditional ceramic insulators in highly contaminating coastal-desert environments.

Design and Test of 500-kV Lightning Protection Insulator

IEEE Access, 2019
In this paper, based on insulation coordination and simulation, a lightning protection composite insulator is proposed, made up of an insulation part and an arrester part connected in series, whose length is close to that of the standard composite ...

Geometric phases and Wannier functions of Bloch electrons in 1-dimension

, 2004
We present a formal expression for Wannier functions of composite bands of 1-D Bloch electrons in terms of parallel-transported Bloch functions and their non-Abelian geometric phases. Spatial decay properties of these Wannier functions are studied in the

Co-operative Kondo Effect in the two-channel Kondo Lattice

, 1998
We discuss the possibility of a co-operative Kondo effect driven by channel interference in a Kondo lattice where local moments are coupled to a single Fermi sea via two orthogonal scattering channels. In this situation, the channel quantum number is not
