Abstract :
The purpose of this paper is to present lightning arrester switching surge voltages and currents, measured during a field test program on a 345-kv system. Surges were produced by energization of a transformer-terminated line and by ultra-high-speed re-energization (UHSR) of arrester-terminated lines. Arrester-sparkover levels were 1.1 to 1.7 pu (per unit) of arrester rating, and arrester follow-current peaks were 135 to 940 amperes.
