Overview
This standard covers protective equipment for series capacitor banks, with a size larger than 10 MVar per phase. Protective equipment is defined as the main circuit apparatus and ancillary equipment, which are part of a series capacitor installation, but which are external to the capacitor part itself. The recommendations for the capacitor part are given in DIN EN 60143-1 (VDE 0560-42)-12:2004. The protective equipment, treated in this standard, comprises the following items: - overvoltage protector, - protective spark gap, - varistor, - bypass switch, - disconnectors and earthing switches, - discharge current-limiting and damping equipment, - voltage transformer, - current sensors, - coupling capacitor, - signal column, - fibre optical platform links, - relay protection, control equipment and platform-to-ground communication equipment. The responsible committee is DKE/K 341 "Leistungskondensatoren" ("Power capacitors") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
