Abstract

The effects of polyvinyl acetate (PVA) on the physical and electrical characteristics of Zinc Oxide (ZnO) varistor were investigated. The mass fraction of PVA was varied into different concentrations of 1%, 5%, 8% and 10%. Results show that the addition of PVA decreases the value of the nonlinear coefficient (a) of ZnO varistor. The decrease in nonlinearity of ZnO is attributed to the shielding of PVA which hinders the creation of grain boundaries that act as schottky barrier.
