This Technical Report refers to high-voltage / low-voltage prefabricated substations (hereinafter prefabricated substations) as specified in IEC 62271-202:2014. This Technical Report may be used for the transferability of type tests performed on one or more prefabricated substations with a defined set of ratings and arrangement of components to another prefabricated substation with a different set of ratings or different arrangement of components. It supports the selection of appropriate representative test objects for that purpose in order to optimize the type testing procedure for a consistent conformity assessment. This Technical Report utilises a combination of sound technical and physical principles, manufacturer and user experience and mutually agreed upon methods of calculation to establish guidance for the transferability of type tests, covering various design and rating aspects.
