DIN IEC/TS 62332-2:2014-12

This part of the DIN IEC 62332 series, published as a Technical Specification, is applicable to all EIS containing solid and liquid components where thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a sealed tube test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). One aspect of this procedure is to provide a method to assign thermal classifications to materials used in EIS where solid and liquid components are both used. The test procedures in this part are applicable to liquid immersed transformer insulation systems. The responsible committee is DKE/K 183 "Bewertung und Qualifizierung von elektrischen Isolierstoffen und Isoliersystemen" ("Evaluation and qualification of electrical insulating materials and systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
