Static dielectric constant and dielectric loss of cellulose insulation: Molecular dynamics simulations

open access: yesHigh Voltage, 2021
Reducing the dielectric constant and loss of cellulose insulation can make the electric field distribution uniform in oil‐paper insulation systems and decrease the heat generation in dielectric materials, thus ensuring a reliable transformer operation ...
