ActiveRotating electrical machines—Stator winding insulation of rotating electrical machines—Part 3: Dielectric dissipation factor measurement
旋转电机 旋转电机定子绕组绝缘 第3部分：介质损耗因数测量
Application Summary AI generated
This standard specifies the test method for measuring the dielectric dissipation factor (tan δ) of stator winding insulation in rotating electrical machines. It is applied during factory acceptance testing, commissioning, and routine maintenance of large generators and motors to assess insulation aging, moisture content, and overall condition. The standard is critical for power plants, industrial motor manufacturers, and electrical testing laboratories to ensure operational reliability and prevent insulation failures.
