TFN Cable Fault Tester System Components

Cable fault tester system: Since it is a system, it has corresponding components.

I take the TFN FB28 cable fault tester as an example

Fault distance measuring unit - CJ76 three-level pulse distance measuring host and central control unit

The host adopts three-level pulse advanced arc reflection pre-positioning technology to make all test waveforms appear as low-voltage pulse waveforms, realizing automatic positioning of the fault point distance, and making fault distance measurement simple and easy. The central control unit is an active energy storage device that can automatically control the first-level high-voltage breakdown fault, the second-level active arc, and the third-level pulse sampling. It is an essential component to realize the three-level pulse method and improve the sampling success rate. 

Tracing and identification unit - T7000 Cable Path Finder

It can quickly and accurately locate the insulation short circuit and open circuit of the faulty cable to the ground, and can also locate the buried cable path and measure the laying depth of the cable. It is a new generation of cable fault test instrument, which reduces the complexity and difficulty of cable fault testing and improves safety. 

Fault location unit - PTR80 intelligent locator

The precise locator equipped in the system has multiple functions such as sound wave and electromagnetic wave digital size display, fault point distance prompt, path monitoring, frequency band selection, storage, etc. At the same time, it is equipped with noise-proof pickup probe and high-impedance military headphones, which makes it have super anti-interference ability and greatly reduces the human experience factor.  

High Voltage Signal Unit - T86 High Voltage Signal Generator with Battery Integration

The energy supply part for cable fault pre-location provides high-voltage and high-energy electric pulses. (The high-voltage generator equipped with the system has the advantages of automatic voltage setting, single or continuous discharge, simple wiring, small size and light weight.) The high-voltage source equipped with the system is a traditional control box, booster, pulse capacitor discharge ball gap, and discharge rod, which are digitally processed by industrial control technology and scientifically integrated into one, realizing true integration. The high-voltage pulse power supply abandons the trouble of adjusting the sound of the ball gap discharge. The interface is a digital LCD display, which shows the working status of the instrument, voltage level, pulse frequency, residual voltage and other information; the wiring is simple (only one power line, one high-voltage line, and one ground line need to be connected), the volume is small and the weight is light, and it basically does not occupy the work space.
