Which is the best detector for multi-pulse cable faults? It is best to use the latest power cable fault tester manufacturer. We need to know who has used it. Thank you.
Product Overview Cable fault detector is a high-tech product. It can analyze and detect various types of power cable short-circuit faults by using modern classic DC high-voltage flashover method, impulse high-voltage inductance sampling method, impulse high-voltage current sampling method, low-voltage pulse method, etc. Various faults such as open circuit, fixed-point circuit fault, high-resistance flashover fault, and high-resistance leakage fault. At the same time, it can also perform preliminary measurement of short-circuit and open-circuit faults of control cables, local telephone cables and coaxial communication cables, and calibrate the total length of the cables.
Technical parameters Test distance: single-ended test distance≤10km shortest test distance (blind zone): less than V/15 (m). Among them, the V wave propagation velocity test error in the cable under test: relative error:≤±2% absolute error: fault point within km≤15m, the fault point above km≤20m reading resolution: V/60m, which is the propagation speed of the V wave in the cable under test. E.g:“Oil-impregnated paper cable”, under the wave propagation speed of 160m/us, the minimum resolution of the instrument reading is 2.66M, that is, the reading changes by 2.6m each time the cursor moves on the screen.
Power supply: AC 220V±10% 50 Hz ambient conditions: Temperature: 0℃~50℃. Relative humidity: 80%? 5% host volume: 350×250×200 (mm) host weight: 5kg Main features It can test various faults of various copper core, aluminum core power cables and local telephone cables of different voltage levels. The instrument presets the wave propagation speed of four commonly used power cables: oil-impregnated paper cable, cross-linked vinyl cable, drip-free cable and plastic cable.
Cable length and fault distance do not require manual conversion. The instrument automatically switches and displays the fault distance. The system consists of a cable fault tester, which is used for the rough measurement of cable faults and is the core of the whole set of instruments; the cable fault fixed-point tester (referred to as fixed-point tester) is used for precise positioning of cable faults, which is the same as the traditional configuration; the cable path tester ( Abbreviation: path meter) is used to find the direction and depth of buried cables, which is the same as the traditional configuration; high-energy high-voltage device: use flash tester to roughly measure various faults; use fixed-point tester to accurately locate various fault points.
There are two configurations: Split structure: including: yd (JZ) series power frequency high voltage test device (including yd (JZ) series power frequency high voltage test transformer and XC series voltage regulating control box, the same as the traditional configuration) Pulse storage capacity (Same as the traditional configuration) Secondary pulse synchronization device integrated structure: The high-voltage secondary synchronization pulse integrated generation device includes all the functions of the split structure.
