Cable fault distance meter, power cables are mostly buried underground, invisible and untouchable. Once a fault occurs,it is very difficult to locate, often taking days or even more than ten days. This not only wastes a lot of manpower and material resources, but also causes incalculable losses due to power outages. With the help of modern new-type power cable fault testing instruments, the fault point can be quickly located, the fault can be eliminated in time, and power supply can be restored.
Main Features
● Combines low-voltage pulse reflection and pulse current testing methods, capable of testing faults such as open circuits, low resistance, high resistance, and flashover.
● High intelligence. It can automatically determine whether the fault point discharges and automatically calculate the fault distance.
● Uses a current sensor to measure the pulse current signal flowing through the ground wire. Compared with traditional flash testers that use resistor-capacitor voltage dividers to measure pulse voltage signals, the wiring is simpler and more convenient; moreover, it electrically isolates the instrument from the high-voltage circuit, ensuring good safety.
● High testing accuracy: when the range is less than 1Km, the testing accuracy is less than ±1m; when the range is greater than 1Km, the testing accuracy is less than 0.5%.
● Uses Chinese menu technology, easy to master and use.
● Can permanently save 20 test waveforms, which are not lost after shutdown, replacing the printer function. Uses a clock marker for easy browsing of waveform archives.
● Uses a large-screen LCD with backlight. The display brightness can be adjusted via buttons.
● Uses rechargeable lithium-ion battery with automatic charging management.
● Small size, light weight, easy to carry.
