ActiveMeasurement method of dielectric dissipation factor of electric machinery coil/winding insulation
电机线圈/绕组绝缘介质损耗因数测量方法
Application Summary AI generated
This standard specifies the measurement method for the dielectric dissipation factor (tan δ) of insulation in electric machinery coils and windings. It is applied in the manufacturing, testing, and maintenance of motors, generators, and transformers to evaluate insulation quality and detect moisture, contamination, or aging. The method is used by electrical equipment manufacturers and power industry professionals for quality control and preventive diagnostics.
