GD-4138H Cable Fault Locating System is important tool to maintain all kinds of cables. It is compatible equipment that can trace, locate the underground cables, with fault distance measurement and HV generation. As it is movable device, it is convenient to carry on-site. If acoustic locator is used together, it can locate accurate position of cable fault point.
Application is underground cable, aerial cable, power cable, local cable, communication cable and fiber cable.
Typical fault to be detected includes
GD-4138H system includes:

GD-4133 Multiple Pulse Cable Fault Tester
It is used to measure fault distance. Under LV pulse mode, it can be used alone.
l 7inch LCD screen, friendly interface.
l Multiple distance locating method:
Ø Low voltage pulse method: it is suitable for the locating of the low resistance fault, short circuit fault, open circuit fault. It also can be used in the measurement of the cable length, the intermediate joints, T joints, and cable termination joint. This method also can be used to correct the wave velocity.
Ø Pulse current method: It is suitable for distance measurement of the high resistance fault, breakdown fault. Using the current coupler to collect signals from the earth wire, it makes the user far away from the high voltage. This method is safe and reliable.
Ø Multiple pulse: the advanced way to measure distance. The waveform is easy to identify and the accuracy is high.
l 200MHz real-time sampling. Max. 0.4m measurement resolution. It has small dead zone and is special for the short cable and near fault cable.
l Touch screen and press key operation. The cursor can be dragged.
l PIP copy(pic. temporary storage)
Ø There will be a main window and three temporary storage windows could check three waveforms together.
l Built-in embedded operating system
Ø Special software management for software upgrade, backup and restore.
l Scale function
Ø One starting point,10 contacts, one cable fault and one full length could be setting.
Ø Display scale and testing waveform at the same time
l Waveform storage and communication with computer.
Ø Internal storage of waveforms.
Ø With USB, to download or upload data
Ø Communication with computer
l Power management
Ø Backlight weakens if no operation in 2mins and power off in 10mins if no operation.
Ø Built-in Polymer Lithium-ion battery.
Ø Working time is up to 5 hours for each use.
Ø Strong case, easy to carry.
