Feature

• 10.1-inch full-color TFT touch screen;

• Embedded system, safe, stable, simple display and operation mode;

• With the function of testing cable wave velocity, cable length and fault distance;

• Fully automatic continuous sampling, waveform capture at all times, timely and accurate.

• With automatic test range setting, automatic waveform analysis and display of test distance.

• Full Chinese menu, touch and coding button two operation modes, simple, fast and reliable.

• With low-voltage pulse method, high-voltage flashover method, multiple pulse method (8 times) test technology, waveform display is smooth and easy to read.

• When using the multiple pulse method, it is used with a pulse coupler to display 8 groups of high and low voltage waveform comparisons, which is convenient for automatic test distance, manual analysis and distance measurement.

• The instrument has powerful data processing capabilities, which is convenient for users to manage and archive waveform files.

• It has a massive test waveform storage function: the waveforms tested on site can be conveniently stored in the instrument in the order specified by the Chinese naming regulations, so that they can be called up for observation and analysis at any time; it can store more than 8,000 low-voltage pulse and high-voltage flashover waveform records, and more than 250 multiple pulse waveform records. The waveform files can be imported into the computer software for management and analysis using USB communication.

• Ultra-high brightness, LED backlight brightness up to 280nit, resolution 1024*600, easy to operate in direct sunlight.

• Built-in large-capacity lithium battery pack, supports fast charging, and can be tested in an environment without power supply.

Technical Parameters

System function

1.Use DC or high-voltage pulse to make the cable fault point flash over and discharge

2.Use the traveling wave reflection principle to make a rough measurement of all types of cable main insulation faults

3. Use the acoustic and magnetic synchronization method to make a precise measurement of all types of cable main insulation faults

Prelocating methods ARC Multishot: The Arc Reflection Method overlays and compares a low voltage reference trace and a high voltage fault trace captured via capacitor discharge through an inductive (coil-type) filter.

8 comparative measurements per ARM shot are displayed (Multishot feature), and the results are evaluated automatically. ICE/Surge Pulse: After fault ignition via capacitor discharge, the Impulse Current or Surge Pulse method measures the current component of the travelling wave, This technique is suitable for long cables and PILC cables.

DECAY: After fault ignition via HV DC source, the DECAY method measures the voltage component of the travelling wave. This technique is suitable for very long cables, HV transmission cables and faults with very high breakdown voltage.

IFL: Intermittent Fault Locating; to find intermittent faults with temporarily changing characteristics like they often occur in street lighting systems.
