Diagnosis of insulation degradation (water tree degradation) of 6kV class CV cables while live. High-precision insulation degradation diagnosis is possible using the AC superimposition method.
The CV cable live line deterioration diagnosis device DISC-20-AS is designed to accurately detect harmful water trees, which account for the majority of insulation breakdown accidents in 6kV class CV cables, allowing for planned cable replacement work. Furthermore, this insulation diagnosis is performed while the line is live, eliminating the need for cumbersome tasks such as notifying of power outages on the tracks. Additionally, since the diagnosis is conducted for all three phases simultaneously, maintenance and inspection of the cables can be carried out efficiently. Moreover, the device can be safely operated by simply attaching it to the existing grounding wire. This device is a model change that retains the basic characteristics and functions of the DISC-10G-AS while improving usability.
