Application Summary AI generated

This standard specifies a method for measuring the average viscometric degree of polymerization (DPv) of cellulosic materials used in electrical insulation, such as transformer board and insulating paper. It is applied in the electrical power industry to assess the mechanical and thermal degradation of new and aged insulating materials, helping to evaluate the remaining service life of transformers and other high-voltage equipment. The measurement is critical for quality control during manufacturing and for condition monitoring during maintenance of power grid assets.
