in three-phase power systems with nominal voltages above 1 kV. iTeh Standards Core Scope and Coverage

. This is the maximum voltage that appears across the terminals of an arrester during the passage of a surge current. Because this parameter directly affects the insulation coordination of the entire substation, the standard provides typical maximum residual voltage values (found in Annex F) to help users match the arrester to their specific system needs. iec 600995 pdf
