Abstract :
This paper describes electrical uniformity of the zinc oxide nonlinear resistor element (ZnO element) used for ZnO arresters. A simple and useful method for the uniformity evaluation makes use of thermography, obtained by an infrared radiation thermo-camera, of the metallized surface. Relationships between uniformity and energy absorption capabilities were obtained experimentally.
