Morphological, structural and physical characterization of commercially available low voltage ZnO-based varistors

Abstract The set of ZnO-based varistors from different manufacturers was examined before and after aging with 8/20 µs current lightning strokes. Aging resulted in an increase in leakage current of up to 25%. Powder X-ray diffraction (pXRD) analysis allowed identifiation except dominant ZnO oxide als...
