摘要
绝缘介质损耗测量是电力系统检测高压电气设备的预防性试验项目,它是判断绝缘介质受潮、老化等整体绝缘劣化状况的一种有效的检测手段。通过在绝缘介质损耗测量中采用变频测量技术,可以大大增强介质损耗测量的抗干扰能力,提高tg%测量的精度。
The dielectric loss measurement is a general item to check the high voltage electric equipment. It is an effective and preventive test to estimate the aging and if the dielectric has been affected with damp. This paper explains that with the frequency conversion technology used in the measurement of high voltage dielectric loss, more interference can be avoided and the precision will be improved.
