Complex applications of surge protection practices may require specialized study by experienced engineers.
This standard applies to devices for separate mounting and to devices supplied integrally with other equipment. Computational guide to insulation co-ordination and modeling of electrical networks This technical report gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendations for the numerical modeling of electrical systems including arresters and for the implementation of deterministic and probabilistic methods adapted to the use of numerical programs.
Artificial pollution testing of surge arresters This standard gives the basic principles of artificial pollution testing of non-linear resistor type valve type surge arresters. Copyright – Isc. It applies to non-linear resistor type gapped surge arresters as defined in IEC and to gapless metal-oxide surge arresters as defined in IEC Surge arrester residual voltage is a major parameter to which most users have paid a lot of attention to when selecting the type and rating.
