GB/T 20139.2-2017 Active
GB/T 20139.2-2017 Electrical insulation systems—Thermal evaluation of modifications to an established electrical insulation system(EIS)—Part 2:Form-wound EIS
Abstract
This part of GB/T 20139 specifies the test procedures required for evaluating the heat resistance of electrical insulation systems (EIS) with defined grades after adjustment. This part applies to EIS using molded winding electrical devices. The test procedures in this part are determined by comparing the performance of the insulation system to be evaluated with that of a reference insulation system. The selected reference insulation system should have performance that meets the requirements of IEC 60505 and operational experience, or has been evaluated in accordance with the procedures specified in GB/T 11021-2014 and IEC 60034-1831:2012.
