FB11 Cable Fault Tester

Highlights

cable fault tester

FB11 consists of four parts.

Cable Fault Location Host -Quickly locate the fault area

  • No test blind area: Combining low-voltage pulse method and high-voltage flashover method to deal with all types of cable faults
  • System accuracy is less than 50 cm, reading resolution is less than 1 meter , and the test distance exceeds 64 kilometers .
  • The fault waveform can be compared with the intact waveform on the same screen, and the fault distance can be automatically determined, which is intuitive and easy to understand.
  • With high-voltage protection measures, it will not freeze or be damaged in high-voltage shock environments

Cable Path Finder – Identify the path of underground cables

  • Supports low-frequency and high-frequency AC signal output to adapt to different site conditions.
  • Signal strength is indicated by digital size, grating lifting and lowering, sound and other methods, making positioning more intuitive.
  • The maximum measurable depth is 2.5 meters , meeting most burial scenarios.
  • Constant power output: Automatically matches the load to ensure the equipment always works in the best condition.

High voltage signal generator – stimulates high resistance fault signal

  • It adopts switching power supply electronic boost, has open circuit and short circuit automatic protection functions, and the box is made of engineering plastic insulation material, which is safe to operate
  • Maximum output voltage <36kV , which can effectively break down high resistance fault points
  • The color LCD screen displays the output voltage in a compass-style dynamic display, which is clear and intuitive.

Acoustic and magnetic synchronous positioning instrument – accurately locate the fault point

  • Acoustic and magnetic synchronization: Synchronously receives the acoustic and electromagnetic waves generated by the fault point discharge, and processes them through the CPU to effectively eliminate interference from environmental noise
  • The LCD screen directly displays the real-time distance between the probe and the fault point , guiding the operator to reach the target directly
  • Ultra-high precision: The positioning error is less than 0.2 meters , which greatly reduces the excavation range and saves manpower and time costs.
