This part of IEC 62271, which is a Technical Specification, applies to indoor enclosed switchgear and controlgear complying with IEC 62271-200 and IEC 62271-201, intended to be used in special service conditions with respect to condensation and pollution deviating from the normal service conditions specified in IEC 62271-1.<\/p>\n

The test detailed in this document has been designed primarily to classify the electrical insulation performance of equipment having high-voltage electrical insulation exposed to indoor service conditions, mainly in presence of condensation. The assessment of mechanical components, such as mechanisms, interlocks and enclosure is also considered.<\/p>\n

In this document, the term “equipment” is used in accordance with the scope for an “enclosed assembly of switchgear and controlgear” (see IEC 60050-441:2000, 441-12- 02).<\/p>\n
