ActiveRotating electrical machines—The winding insulation—Part 5：Off-line measurement of partial discharge inception voltage under repetitive impulse voltage
旋转电机 绕组绝缘 第5部分：重复冲击电压下局部放电起始电压的离线测量
Application Summary AI generated
This standard specifies the method for off-line measurement of partial discharge inception voltage in rotating electrical machine windings when subjected to repetitive impulse voltage. It is applied in the testing and evaluation of insulation systems for motors and generators, particularly in inverter-fed applications where windings experience voltage surges. The standard is used by manufacturers and maintenance engineers to assess insulation quality and predict service life under pulsed voltage conditions.
