Cable Fault Test System

Application:

Intelligent cable fault tester is our company in the power industry rapid progress opportunity, according to industry development and market demand, research and development and production of power cable fault test special system equipment.

It is mainly used for power cable open circuit, short circuit, ground, low resistance, high resistance flash-over and high resistance leakage fault test, as well as coaxial communication cable and local cable open circuit, short circuit fault test. It can also measure the speed of the wave, determine the length of the cable, etc., and can establish cable files for daily maintenance and management.

The product adopts the world's highest level of time domain reflectometry technology, fault waveform automatic distance judgment, simple and clear, easy to use; The whole machine adopts industrial control plastic chassis, small and delicate, easy to carry; The human-machine interface is friendly, even if non-professional personnel operate, you can still quickly get familiar with and use, efficient and accurate to complete the cable fault test.

 Features:

◆It is used for all kinds of faults of power cables of different grades, different sections, different media and various materials in 35kV and below.

Including: open circuit, short circuit, low resistance, high resistance leakage, high resistance flash-over fault.

◆Can cooperate with high-voltage equipment to realize the traditional cable fault test of low-voltage pulse method, impact flash-over method, speed measurement method (multiple pulse

pulse method optional).

◆All English operation software and user interface, sub-menu and text prompts to achieve human-machine interaction.

◆Industrial 10.4 inch color touch LCD display, all English operating software and user interface, submenu mode and text show human-machine interaction.

◆The global waveform and local waveform are displayed synchronously, which is convenient for overall analysis and detailed adjustment.

◆Built-in power supply, can be used for a long time in the environment without power supply.

◆Small size, light weight, easy to use, high failure detection success rate and test accuracy.

◆Stable performance in any environment, does not crash, signal acquisition high-voltage protection measures are safe.

◆Built-in storage/retrieval function, which can easily save or retrieve data and waveform for re-analysis.

◆The test signal provides a variety of pulse width, no test blind area.
