Insulation co-ordination - Part 14: Application procedures for AC/DC filters
Käsitlusala: This part of IEC 60071 applies guidelines on the procedures for insulation co-ordination of AC filters and DC filters for high-voltage direct current (HVDC) converter stations, whose aim is evaluating the overvoltage stresses, transient currents and energies on AC /DC filters sub-system, and determining the specified withstand voltages for their components.
This document applies only to metal-oxide surge arresters without gaps, which are used in AC /DC filters. This document involves the criteria for determining the protective levels of series and/or parallel combinations of surge arresters used to ensure optimal protection, typical arrester protection schemes and stresses of arresters.
