Cable fault tester is a professional equipment used to detect cable faults. It can quickly and accurately determine the fault waveform, detect open circuit, short circuit, grounding, low resistance, high resistance flashover and high resistance leakage faults, as well as open circuit and short circuit faults of coaxial communication cables and local cables. In addition, it can also test cable paths, burial depths, as well as radio speed measurement, and determine cable lengths.
Cable fault testers are widely used in various industries such as power, communication, petrochemicals, coal mines, metallurgy, aerospace, etc. It adopts multiple fault detection methods, combined with computer technology and special electronic technology, and has the characteristics of intelligence and complete functions.
In short, cable fault tester is an important tool for maintaining the normal operation of cable lines, which can quickly and accurately detect and locate faults, improve the efficiency and safety of line operation.
The steps to use a cable fault tester are as follows:
1. Check if the instrument has sufficient power. If the power is insufficient, an external power source needs to be connected.
2. Connect the wires properly, turn on the power switch, and the instrument will enter the interface of the cable fault testing system.
3. According to the actual situation of the tested cable, such as cable type, test cable length, and the nature of cable faults, input test parameters into the cable fault testing system.
4. The default cable testing method for the instrument is the low-voltage pulse method. After setting the cable fault parameters, connect the red and black test wire clamps to the faulty phase of the tested cable and the other good phase, or to the cable ground wire. At this point, you can click "Sampling", and the instrument will automatically test and collect data and display waveform data. When clicking "Sample" again, the instrument can continuously sample. The operator adjusts the "position" and "amplitude" based on the data waveform displayed by the instrument until the collected data can be analyzed, and then the sampling can be stopped.
5. Select the testing method that meets the testing requirements based on the actual situation of cable fault testing. If it is a "high-voltage flashover method" testing cable fault, after clicking "sampling", the instrument enters a waiting sampling state until the instrument performs high-voltage flashover on the faulty cable. The cable fault testing system automatically displays the collected signal and enters the waiting sampling state again, preparing the signal for the next high-voltage flashover. The operator can adjust the "displacement" and "amplitude" during the sampling process until the waveform is convenient for test and analysis. Then the sampling can be stopped, and the cursor operation can be performed to know the cable length from the fault point to the test end, so as to find the cable fault point.
Please note that the above steps may vary depending on the specific instrument model and cable failure situation. When using a cable fault tester, please refer to the instrument manual and follow the safety operating procedures. If necessary, you can contact professional technical personnel for guidance.
The ZC-700A2 cable fault tester is a new generation portable cable fault testing instrument carefully designed and manufactured by our company based on user requirements and considering on-site use. The equipment mainly consists of three parts: flash testing, tracking, and positioning. It can be used to detect low resistance, high resistance, short circuit, open circuit, leakage faults, and flashover faults of various cables. It can accurately detect the fault location, cable length, and cable burial path of underground cables. It has the characteristics of accurate testing, high intelligence, wide adaptability, stable performance, and lightweight portability. The instrument adopts an English system with high-definition display and a user-friendly interface.
Cable tracing and fault location are composed of a path finder, a fixer, a T-shaped probe, an A-frame, a receiver, etc. This instrument is a specialized instrument for cable fault location testing, suitable for testing various cables with metal conductors (wire pairs, protective layers, shielding layers). Its main function is to locate and test points with poor ground insulation, detect cable paths, and test cable burial depth.
