适用范围：IEC/TS 60815-1, which is a technical specification, is applicable to the selection of ceramicand glass insulators for a.c. systems, and the determination of their relevant dimensions, tobe used in high-voltage systems with respect to pollution.This part of IEC 60815 gives specific guidelines and principles to arrive at an informedjudgement 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/TS60815-1.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, etc. to the RUSCD;~ if required, determine the appropriate test methods and parameters to verify the performance of the selected insulators.
