Electrical insulation systems (EIS). Thermal evaluation of combined liquid and solid components - General requirements Ingestion-build-146508 It provides for two classes1 Scope This part of IEC TS 62332 is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a dual temperature test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS).
