Description

BS PD IEC/TR 62271-307 – High-voltage switchgear and controlgear

BS PD IEC/TR 62271-307:2015, which is a Technical Report, refers to prefabricated metal-enclosedand solid-insulation enclosed (both hereinafter called enclosed) switchgear and controlgearassemblies for alternating current of rated voltages above 1 kV and up to and including 52 kVas specified in IEC 62271-200 and IEC 62271-201, and to other equipment included in thesame enclosure with any possible mutual influence.

This Technical Report may be used for the extension of the validity of type tests performed onone test object with a defined set of ratings to another switchgear assembly of the samefamily with a different set of ratings or different arrangements of components. It supports theselection of representative test objects composed of functional units of a family of switchgearand controlgear aimed at the optimization of type tests in order to perform a consistentconformity assessment.

This Technical Report utilises a combination of sound technical and physical principles,manufacturer and user experience and calculations to establish guidance for the extension ofvalidity of type tests, covering various design and rating aspects.
