適用范圍：IEC/TS 60815-3, which is a technical specification, is applicable to the selection of polymerinsulators for a.c. systems, and the determination of their relevant dimensions, to be used inhigh voltage systems with respect to pollution.This part of IEC/TS 60815 gives specific guidelines and principles to arrive at an informedjudgement on the probable behaviour of a given insulator in certain pollution environmentsThe contents of this technical specification are based on CIGRE 33.13 TF 01 documents [1],[2]1, which form a useful complement to this technical specification for those wishing to studyin greater depth the performance of insulators under pollutionThis technical specification does not deal with the effects of snow or ice on pollutedinsulators. Although this subject is dealt with by CIGRE [3], current knowledge is very limitedand practice is too diverseThe object of this technical specification is to give the user means to~ determine the reference unified specific creepage distance (USCD) from site pollution severity (SPS) class,~ choose appropriate profiles,~ apply correction factors for altitude, insulator shape, size and position, etc to the reference USCD.
