Overview
This Technical Specification IEC/TS 60815-1 is applicable to the selection of ceramic and glass insulators for a.c. systems, and the determination of their relevant dimensions, to be used in high-voltage systems with respect to pollution. This part of IEC 60815 gives specific guidelines and principles to arrive at an informed judgement on the probable behaviour of a given insulator in certain pollution environments. The basis for the structure and approach of this part of IEC 60815 is fully explained in IEC/TS 60815-1. The object of this technical specification is to give the user means to: - determine the reference unified specific creepage distance (RUSCD) from site pollution severity (SPS) class; - evaluate the suitability of different insulator profiles; - determine the necessary USCD by applying corrections for insulator shape, size, position, etcetera to the RUSCD; - if required, determine the appropriate test methods and parameters to verify the performance of the selected insulators. The responsible committee is DKE/K 451 "Isolatoren" ("Insulators") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
