Product Description
XHHD523
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.

Function specification
A) Microammeter: indicates the size and direction of the signal
B) Gear switch: "0" indicates off state;
"I" file can be used for step voltage test mode and receiving clamp test mode;
Suitable for the test environment with weak input signal (internal amplifier circuit);
"II" file can only be used in step voltage test mode;
Suitable for the test environment with strong input signal (no internal amplifier circuit);
C) Input: signal input interface, used to connect A frame or receiving clamp;
D) Adjustment: Adjust the amplitude of the input signal;
E) Zero: the reference basis for adjusting the signal in the "I" file mode; Does not work in "II" mode;

Working principle
1. positioning function
The 220VAC power supply input from the power grid is converted into a high-power special signal required for identification by full wave rectification. This signal is added to the unpositioned cable through the connection line. The cable fault can be accurately fixed by measuring "step voltage method" or "current method".
2. withstand pressure function
Switch the function key to the voltage withstand function, you can output 0-10kV voltage, and perform voltage withstand test on the cable.
