This third edition cancels and replaces the second edition published in Surge iec 60099 residual voltage is a major parameter to which most users have paid a lot of attention to when selecting the type and rating.
Typical maximum residual voltages are given in Annex F. It applies to gapless metal-oxide surge arresters as defined in IECto surge arresters containing both series and parallel gapped structure — rated 52 kV and less as defined in IEC and metal-oxide surge arresters with external iec 60099 gap for overhead transmission and distribution lines EGLA as defined in IEC The user of surge arresters will, in that case, not be required to apply the whole process introduced here to any new installation iec 60099 the selection of characteristics resulting from prior practice may be iec 60099.
