Ferromagnetic‐Based Charge‐Accumulation Triboelectric Nanogenerator With Ultrahigh Surface Charge Density

Small, 2022
AbstractAn encouraging micro‐energy harvesting technology, the triboelectric nanogenerator (TENG), has been proven to transfer ambient environmental micro‐energy into electricity, but a low surface charge density results in low performance and limits the practical application of TENG.

Insulator surface charge accumulation under impulse voltage

IEEE Transactions on Dielectrics and Electrical Insulation, 2004
The surface charge distribution under impulse voltage is measured using a static capacitance probe. A probe with very small charge leakage is designed. The condition of surface charge accumulation under impulse voltage is analyzed, and it is concluded that micro discharges in the gas near the insulator surface such as the corona caused by free and ...

Understanding surface charge accumulation and surface flashover on spacers in compressed gas insulation

IEEE Transactions on Dielectrics and Electrical Insulation, 2018
Surface charges have the effect of changing the electric field over spacers in compressed gases, which may affect the stable operation of gas insulated equipment and could possibly trigger a catastrophic surface flashover without warning. In this paper, we review the literature on surface charge accumulation and related surface flashover phenomenon on ...
