DIN IEC/TS 62271-304 VDE V 0671-304:2020-10

High-voltage switchgear and controlgear

Part 304: Classification of indoor enclosed switchgear and controlgear for rated voltages above 1 kV up to and including 52 kV related to the use in special service conditions with respect to condensation and pollution

(IEC TS 62271-304:2019)
Class/Status: Standard, valid
Released: 2020-10
VDE Art. No.: 0600284

This technical specification applies to indoor enclosed switchgear and controlgear complying with IEC 62271-200 and IEC 62271-201, intended to be used in service conditions more severe with respect to condensation and pollution than the normal service conditions specified in IEC 62271-1.
The test detailed in this technical specification have been designed primarily to investigate the behaviour of electrical insulation and not corrosion on equipments.
