IEC/TS 62332-1:2011(E) 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). The following significant technical changes with respect to the previous edition have been made – Modifications have been made based on an extensive test series conducted using this methodology given in the first edition. This included updating expected times and tempertatures to use in order to obtain useful results, as well as making the range of equipment covered broader. The method can now cover electrotechnical devices using different sealing systems, as well as devices using enamel covered wires.
