K Murugesan 01 01 This paper investigates the partial discharge PD characteristics of the lowdensity polyethylene LDPEcomposite materials with plasma treated boron nitride BN nanoparticles With BN surface derivatization of BNthrough plasma treatment in the LDPE matrix makes nanoparticles disperse more efficiently and internanocompatibility Improved interfacial bonding due to higher trapping properties and reduced charge mobility suppressesactivity of PDs to a large extent In comparison with untreated BN composites experimental studies show greatenhancement in dielectric characteristics such as PD inception voltage and discharge value These findings indicatethat plasmatreated BN can be promising to serve as a nanofiller in the insulation of polymer highvoltage designs toimprove its reliability Copyright (c) Journal of Engineering Technology and Sciences.
