recommendations! Published in 2017 at "Advanced Engineering Materials"

DOI: 10.1002/adem.201600677

Abstract: Electrical barriers at the grain boundaries of ZnO varistors are altered by mechanical stresses, which, therefore, play an important role regarding the functionality of the material. The stresses lead to the modification of electrical properties… read more here.

DOI: 10.1016/j.jeurceramsoc.2019.06.043

Abstract: Abstract Here, we analyzed the internal structure of ZnO varistors with X-ray micro-CT technology and showed that the porosity and pore volume at the radial edge is considerably higher than at other regions. Experimental results… read more here.

DOI: 10.3390/app15179484

Abstract: Metal-oxide surge arresters (MOSAs) are critical devices for overvoltage protection in power systems, and the aging characteristics of their zinc oxide (ZnO) varistors under impulse and power-frequency voltages exhibit significant differences. However, traditional methods for… read more here.
