Research on High Frequency Partial Discharge Detection Technology of Inverted Current Transformer

在倒立式电流互感器运行时不能快速、有效地检测其绝缘状态,当出现绝缘故障时会造成较大的经济损失和社会影响。文中介绍了一种基于高频局部放电检测法的现场检测技术,设计出专用检测主机和传感器,具有灵敏度高、易于操作的特点,可有效地检测出互感器内部的局部放电信号。

Inverted current transformers can not detect the insulation state quickly and effectively during operation. When there is insulation fault, it will cause large economic loss and social impact. In this paper, a field detection technology based on high frequency partial discharge detection method is introduced, and a dedicated detection host and sensor are designed. With high sensitivity and easy operation, it can effectively detect the partial discharge signal inside the transformer.
