Underground cable sheath fault locator
With the city network development, many power supply bureau, construction, and even the design institute are first met 110kV XLPE cable, due to time and lack of experience, resulting in many cable outer sheath can't passed withstand voltage test (10kV/1min). At present, the external protective layer mostly uses HDPE sheath material, passed the DC 25kV/5min withstand voltage test before out of factory, the leakage current is less than dozens of µA. Therefore, after the laying of defects mostly by laying, including external damage during filling and covering process. The defects include termite bites; ground box with water; deterioration of the original defects; grounding wire or part moisture penetration insulation resistance decreased and other reasons, sometimes because the cable buried too deep, or the complexity of the situation around buried cable, so that the positioning is very difficult, some defects can't be solved after many years, with the hidden danger to run.
The step voltage method and the clamp current method are mainly used for the precise location of the fault of the outer sheath of the single-core cable, and the precise location of the ground fault of the unarmored wire and cable. ★Main features: adjustable voltage, adjustable frequency, overcurrent protection, fixed-point, withstand voltage one-key switch, no blind zone in the test range, adjustable receiver sensitivity, signal frequency adjustment, zero protection.
