What is PD CLC IEC/TR 62271-307 on AC enclosed switchgear and control gear about?
PD CLC IEC/TR 62271-307 is an international standard that covers guidelines for high-voltage switchgear and control gear.
PD CLC IEC/TR 62271-307 refers to prefabricated metal-enclosed and solid-insulation enclosed (both hereinafter called enclosed) switchgear and control gear assemblies for alternating current of rated voltages above 1 kV and up to and including 52 kV as specified in IEC 62271-200 and IEC 62271-201, and to other equipment included in the same enclosure with any possible mutual influence.
PD CLC IEC/TR 62271-307 specifies terms, use and application of extension criteria, and other technical aspects like dielectric tests temperature rise test, mechanical tests, etc., for extending the validity of type tests of AC enclosed switchgear and control gear.
Who is PD CLC IEC/TR 62271-307 on AC enclosed switchgear and control gear for?
PD CLC IEC/TR 62271-307 on AC enclosed switchgear and control gear is useful for:
- Manufacturers and suppliers of AC switchgear and control gear
- Dealers and distributors of AC switchgear and control gear
- Designers of AC switchgear and control gear
- Test /service providers for AC switchgear and control gear
Why should you use PD CLC IEC/TR 62271-307 on AC enclosed switchgear and control gear?
A metal or solid insulation enclosed switchgear and control gear assembly is enclosed entirely from all the edges (other than ventilating openings and inspection windows) by using insulating material or sheet metal. It helps in the protection of the switchgear and control gear assembly.
PD CLC IEC/TR 62271-307 gives you measures for extending the validity of type tests performed on switchgear assembly of the same family with a different set of ratings or different arrangements of components. It also helps for the selection of test objects having functional units of AC enclosed switchgear and control gear. It aids you in the optimization of type tests in order to perform a consistent conformity assessment.
PD CLC IEC/TR 62271-307 gives you a complete package of sound technical and physical principles, manufacturer and user experience, and calculations to establish guidelines for the extension of validity of type tests, covering various designs and rating aspects.
What’s changed since the last update?
PD CLC IEC/TR 62271-307:2019 supersedes PD IEC/TR 62271-307:2015, which is withdrawn.
