Surface charge accumulation and decay in electrospray printing

Journal of Physics D: Applied Physics, 2020
Abstract In electrospray printing, the accumulation of electric charge on the target substrate plays an important role in governing the structure of the deposit. To better understand the effect of charge, we report on the use of two methods to measure the rate of charge accumulation and decay on dielectric substrates targeted with ...

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 ...

Temperature Dependence of Surface Charge Accumulation on DC-GIS Insulating Spacer

IEEE Transactions on Power Delivery, 2022
Surface charge accumulation on an insulating spacer is a critical issue that causes electric field distortion and flashover voltage reduction in DC-GIS. In the operating environment, high-voltage electrode is heated by Joule heat, and the surface charge ...

Surface charge accumulation and decay on directfluorinated oil-impregnated paper

IEEE Transactions on Dielectrics and Electrical Insulation, 2016
The oil-impregnated paper, as a vital part in the oil-paper insulation system, serves as the main insulation medium in converter transformer suffering various electric fields. However, the accumulated surface charge on the paper would accelerate the degradation of insulation system and may lead to surface flashover.
