Study on the ageing of insulators based on the surface charge accumulation process
The Journal of Engineering, 2019 In order to study the transient motion of the space charge around the air tower insulator and the charge distribution of the insulator, a two-dimensional mixed numerical model of the insulator string based on chemical reaction is proposed. The simulation

Tower Air-gaps discharge characteristics and insulation coordination for UHV AC double-circuit line
The Journal of Engineering, 2019 In order to give out inverse V-type insulator tower air-gaps configuration of double-circuit UHV AC power transmission line, different distance air-gaps from high-voltage electrode to tower frame discharge tests of inverse V-string are carried out ...

Wilson-Loop Characterization of Inversion-Symmetric Topological Insulators
, 2014 The ground state of translationally-invariant insulators comprise bands which can assume topologically distinct structures. There are few known examples where this distinction is enforced by a point-group symmetry alone. In this paper we show that 1D and

More than Insulator: Multiple Roles of CTCF at the H19-Igf2 Imprinted Domain
Frontiers in Genetics, 2012 CTCF-mediated insulation at the H19-Igf2 imprinted domain is a classic example for imprinted gene regulation. DNA methylation difference in the imprinting control region (ICR) is inherited from the gametes and subsequently determines parental allele ...

Holographic classification of Topological Insulators and its 8-fold periodicity
, 2012 Using generic properties of Clifford algebras in any spatial dimension, we explicitly classify Dirac hamiltonians with zero modes protected by the discrete symmetries of time-reversal, particle-hole symmetry, and chirality.

Natural Contamination and Surface Flashover on Silicone Rubber Surface under Haze–Fog Environment
Energies, 2017 Anti-pollution flashover of insulator is important for power systems. In recent years, haze-fog weather occurs frequently, which makes discharge occurs easily on the insulator surface and accelerates insulation aging of insulator.
