Cable Fault Locating Device

Features:

An integrated fault location system featuring multi-stage DC high-voltage generators, multi-stage high-voltage impulse capacitors, automatic ignition/discharge sphere gap units, multiple-pulse arc stabilization units, current coupling units, and centralized automatic control units, all in one, for easy operation.

2. The switching between three test methods and two voltage levels is achieved through low-voltage low-power control.

3. Leading-edge testing methods make diagnosing complex faults incredibly simple.

Low technical skill requirements for equipment operators.

5.8/16KV, with a shock energy output of up to 1408J per step, longer ranging and arc extension time, and a loud fault point sound during pinpointing.

5. The spacious wheels ensure stability, making them easy to transport and suitable for on-site work.

Technical Indicators:

1. Testing Methods: Arc Reflectance Method/Multiple Pulse Method, Current Sampling, Direct Current Output.

2. Sampling Signal Types: Arc Reflection Method/Multiple Pulse Method, Current Sampling, Low-Voltage Pulse.

Direct Current High Voltage Output:

0-16KV Negative Polarity, High Output Current: 76mA

0-8KV Negative Polarity: High Output Current: 152mA

4. Surge Capacitor:

0-16KV, 11μF, High Output Energy of 1408 Joules

0-8KV, 44μF, High Output Energy of 1408 Joules

When operating at low voltages, it provides a more powerful shock energy (the shock energy at low voltages is several times that of a single capacitor), making it easier to pierce cable fault points, and the pinpointing sound is loud and clear. The insulation of the tested cable will not sustain secondary damage due to fault location.

5. Pulse Discharge Across Gap: The low-voltage controlled solenoid valve regulates air gap, with a discharge cycle adjustable from 3 to 12 seconds. It also features a specially designed noise reduction device to meet the requirement for silence in the event of cable fault at the starting end.

6. Protection:

Zero-Voltage Position Protection: Prevents accidental operation and ensures safety for both personnel and the tested product.

Upon pressing the "Disconnect" button, the residual charge is quickly and automatically discharged through internal safety devices, ensuring safety.

Impact Energy: E = (C * U²) / 2
