U c has to be considered only when the actual system voltage is higher than the tabulated. Any arrester with U c higher than or equal to the actual system voltage divided by 3 can be selected. 2) With prior duty equal to the maximum single-impulse energy stress (7.0 kj/kv (U r )). Arresters with lower or higher rated voltages may be available on request for special applications. A Surge Arresters uyer s Guide Technical information 59
