  Reliable performance of a Zinc Oxide surge arrester is highly dependent on its energy absorption capability. This paper presents two simple but promising approaches for enhancement of this property: one with an alternative sintering orientation and the other with the changed geometry of arrester discs to provide higher surface to volume (S/V) ratio. Several sintering orientations including the control (or conventional) process were tried and assessed. Some of these attempts have demonstrated quite superior results which might be linked to lower level of contamination during sintering. Study conducted to observe the effect of the higher surface to volume (S/V) ratio through geometrical modification of the discs from cylindrical to hexagonal shape has also demonstrated improved outcome. Average energy absorption capability for the hexagonal discs was found to increase markedly which mig.. Read More»
