Abstract

This paper reports the stability against surge of ZnO-$Pr_6O_{11}$-CoO-$Cr_2O_3-Er_2O_3$-based varistors sintered at different sintering temperatures. As sintering temperature increases, the varistor voltage decreased in the range of 412${\sim}$266 V and the nonlinear exponent decreased in the range of 61${\sim}$50. Meanwhile, the stability against surge with surge peak current of 100 $A/cm^2(8{\times}20{\mu}s)$ exhibited to be good on the whole.
