Scope and object
IEC/TS 60815-1, which is a technical specification, 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, etc. to the RUSCD;
• if required, determine the appropriate test methods and parameters to verify the performance of the selected insulators.
