Cable intelligent precise locator price buried cable ground fault, whether there is instrument to find the fault point, Shenzhen Noyafa cable fault intelligent tester main features Locator price buried cable ground fault, whether there is an instrument to find the fault point, Shenzhen Noyafa Cable Fault Intelligent Tester Main Features . The instrument adopts low-voltage pulse method and high-voltage flashover method for detection, which can test various faults of cables, and directly test the flashover and high-resistance faults of power cables without burning through. If equipped with a sound point meter, the position of the fault point can be accurately determined. 2. The test accuracy is high.
The instrument adopts high-speed data sampling technology with a reading resolution of 1m. High degree of intelligence. The test results are automatically displayed on the large-screen LCD screen with small size and data, and the fault diagnosis is intuitive.
It is also equipped with a menu display operation function, which does not require special training for operators. 3. It has the functions of wave opening and parameter storage and recall. Using non-volatile devices, the waveform and data are not easily lost after shutdown.
4, with dual trace display function. The test waveform of the faulty cable can be compared with the normal waveform, which is conducive to further judgment of the fault. 5. It has the function of waveform expansion ratio.
Change the waveform scale and expand the waveform for accurate testing. 6. Control the measurement cursor, can automatically search along the line, and automatically stop at the inflection point of the fault waveform. 7. The position of the double cursor can be changed arbitrarily, and the direct distance or relative distance between the fault point and the test point can be directly displayed.
8. With printing function. Print and archive the test results. Main technical parameters 1. The longest test distance: 32km2, the detection blind area: 1m3, the reading resolution: 1m4, the power consumption: 5VA5, the volume: 325×165×225mm36, weight: 4Kg It is composed of transmitter and receiver, inductive probe, potential difference probe and so on.
The instrument uses electromagnetic induction method to conduct routing tracing and buried depth test on optical cable and cable, and uses potential difference method to conduct fault location test on optical cable and cable. It is suitable for all kinds of optical cables with metal conductors (pairs, sheaths, shielding layers), routing of cables, buried depth and location testing of poor insulation points to the ground. It is a dedicated tester for line faults in post and telecommunications systems and units such as troops, railways, mines, oil fields, airports, and shipping.
Features of the instrument 1. High receiving sensitivity 2. Small static drift 3. Strong anti-interference ability 4. High accuracy, stable operation 5. AC and DC dual-use 6. LCD digital display Main technical indicators Distance: 3km for cables with diameter less than 0.5, other cables up to 20 km. 2. Accurately fixed fault insulation resistance value: 0-50MΩ. 3. Positioning test accuracy:≤±10cm4. Probe cable depth:≤3m type DC high voltage generator The high voltage generator is an integral part of the cable fault detection system, and is used as an auxiliary high voltage power supply when using the impulse flashover method to detect high resistance faults.
