초록

In the standard system of low voltage-oriented ZnO varistor,a small amount of $Sb_2O_3$ was added to improve the nonlinear exponent and then to find the variation of breakdown characteristics, 0.1m/o-SiO and 0.1m/o-$TiO_2$, respectively,were added We considered relationship between the breakdown voltage of systems and the microstructure. We found that the system containing 0.1m/o-$Sb_2O_3$ showed very high nonlinear exponent. And we found that SiO enhanced breakdown voltage and $TiO_2$ lowered it.
