Scope: This standard presents the thermal evaluation and classification test procedures used or recommended for the modification of the insulation structure of random wound windings and the substitution of insulation components. This test procedure is to compare the performance of the insulation structure to be evaluated with the performance of the reference insulation structure that has been proved by experience or has been evaluated according to one of the procedures in GB/T 17948.1-2000, and predicts the feasibility of its change or substitution.
