Surge arresters. Protecting equipment from heatstroke

The authors outline how the main consideration for properly designing a ZnO arrester is the thermal behavior of its components (i.e., their heat transfer properties). They argue that the analysis should be carried out not only in the steady-state of the device, but also in the dynamic and the transient states. Each element must be designed so that the energy handling capability of the assembly is appropriate for the specific duty. Even though manufacturers have achieved outstanding progress in ZnO technology, researchers are working to develop even better devices.
