Product Description

XHHD523L Cable Fault Sheath Locator

Designed based on the principle of MURRAY Bridge. The equipment has the characteristics of high voltage, light weight,convenient operation and High voltage Cable sheath fault locator.

* The high-resistance breakdown point of the cable after laying, especially the linearhigh-impedance breakdown point that is difficult to fire into low resistance, such as the linear high-resistance breakdown of the middle connector of the cable.

* Flashover type breakdown point, after the breakdown, the constant current source can maintain the arc, there is a stable current through the bridge, and the bridge has sufficient sensitivity.

* Has not broken down, but the defect point of low resistance, such as the use of Meg ohm meter found low cable resistance, but the operating voltage does not break down the insulation defect point.

Testing step:

1. Check the breakdown status of the cable with a multimeter, a rocking watch or other pressure resistant equipment, and record the value of each core's insulation resistance against the ground or residual voltage breakdown.

2. Record the length, model, cross section and other parameters of the cable to be tested, and inspect the route along the cable laying path. In the remote short-circuit fault cable and the auxiliary cable outlet terminal, leave one person at the remote monitoring to avoid high-pressure injury.

3. wiring. The ground of the instrument is reliably connected to the grounding body of the positioning site.
Ground rods are connected to the instrument ground. The measuring head (black clip) is connected to the faulty cable core and the
measuring end (red clip) is connected to the auxiliary cable core.

4. bridge zero (high voltage knob is not zero). Turn on thepower and rotate the zero button to zero the galvanometer.

5. power supply connected to AC220V.

6. Boost pressure. Turn on the power switch and the power indicator lights up. When the high pressure knob is turned counterclockwise, the zero position is activated.

7. Turn the high pressure knob clockwise and watch the voltmeter and ammeter until the ammeter exceeds 5mA. If the current is not stable, the voltage may continue to rise for a period of time to form a stable arc or conductive area, stabilizing the current during the test.

8, balance adjustment. Rotate the zoom knob clockwise to increase the sensitivity step by step until
the galvanometer deflects significantly but does not overshoot. Rotate the dial to make the galvanometer zero. (If the pointer is to the left, rotate clockwise, the pointer is to the right, and counterclockwise). Take note of the reading P1 of the cymbal dial at this time.

9, drop voltage, discharge. The clamp exchange position will be measured and steps (4) to (10) will be repeated to
obtain another reading P2, which should have P1+P2=1000

10. Calculation. Location of fault point X=2×L ×P1‰ Pay more attention to
the "2" in the formula. The auxiliary cable will double the number of cables involved in the calculation.
