摘要：
Oil-immersed inverted current transformers are widely used in power systems with voltage levels of 110kV and above. The insulation breakdown of oil-immersed inverted current transformer leads to a large explosion hazard. In order to solve this problem, deployed a wide frequency device for partial discharges based on the pulse current method. The article presents a preliminary exploration of partial discharge identification in oil-immersed inverted current transformers using a wide frequency device. The device employs the pulse current method to capture partial discharge data, which is then analyzed through cluster analysis, algorithmic judgment, and data visualization with manual judgment. The approach offers a promising tool for enhancing the safety and reliability of these critical electrical equipment.
