Abstract

An arrester includes at least one elongate outer first housing made of an electrically insulating material, a pair of electrical terminals at opposite ends of the first housing, an array of electrical components arranged in the first housing that form a series path between the terminals, and a voltage grading arrangement for providing a substantially uniform voltage gradient along the arrester, wherein the voltage grading arrangement includes (i) an elongated outer second housing, and (ii) capacitor circuitry arranged in the outer second housing, and wherein the outer second housing is arranged external to the outer first housing.
