Product Description

Power Hv Underground Cable Fault Locator Optical Power Meter
 

Product Description

 

This Underground Cable Fault Locator can test all types power cable (voltage class 1KV~35KV) , local cable, FM communication cable, coaxial cable, short circuit, earth, high resistance leakage, high resistance flashover fault of the metal overhead lines, and the broken & poor contact of the cable. It also can test the length of the cable and the speed of the electric wave on the cable. 

To test the HV arcing fault of cable, earthing high &low resistance, short circuit and breakage of the cable, poor contact, etc.; If equipped with fault locator, it can decide the exact broken position of the cable ,applies to power cable in various type, voltage and communication cable.

 

Product Features

 

1. Multi functional, safe, fast speed and accurate. It uses LV impulse method and HV flashover method to test, can test kinds of fault of the cable, if equipped with sound locator, can accurately the position of the fault point.

2. High precision, adopts high-speed sampling technique, A/D sampling speed is 100MHz, resolution is 1m, detection blind area is 1m.

3. High degree of intelligence, test results auto displayed by LCD.

4. Can store and review the waveform and parameters, these information will not loss after power off.

5. Dual display, compare the measured waveform and normal waveform of the fault cable, benefit to further detection of the fault.

6. With function of wave form expansion ratio, change the proportion of the waveform, expand the waveform to test.

7. Directly display the direct distance or relative distance between fault point and measured point.

8. Can modify the speed according different measured cable.

9. Portable design , small in volume , with rechargeable battery, easy to carry and operate.

 

Working Principles

 

1. Voltage reflection method: Input high-voltage pulse or sine wave signals at one end of the cable and analyze the magnitude and direction of reflected signals to determine fault distance.

2. Pulse echo method: Send narrow pulse signals into the cable and calculate the fault distance based on the return echo signal receiving time.

3. Electromagnetic induction: Place electromagnetic detection coils along the cable route to detect magnetic field changes at fault points.

4. Simulation radio frequency: Input RF signals into the cable and analyze signal reflections at the fault point to determine the fault location.

5. Audio frequency spectrum: Analyze changes in the audio frequency spectrum propagating through the cable and identify fault types and locations based on spectral characteristics.

6. Thermal sensing: Use infrared thermal imagers to detect heat anomalies at cable fault points.

7. Ground penetrating radar: Use GPR to detect cable routes and faults.
