Abstract

One of the most important parameters of the protective performance of ZnO surge arresters is the residual voltage. In laboratory tests on standard arresters, a thin ZnO disc with a central hole is used in order to pick up the voltage, and a system with a double shielding technique reduces outside effects. Comparative tests of voltage signals from this series divider with those from a conventional parallel connected divider show that inductive overshoot is avoided.
