ST-900 Power Cable Fault Locator

ST-900 power cable fault locatoradoptsthe circuit specially designed for the reflection characteristics of power cables. The test results are more accurate, stable and intelligent. It is an essential tool for power cable test and maintenance. It can position the power cable fault distance advanced through low-voltage pulse ranging or pulse current ranging, which greatly improved the test efficiency.

(Note: The pulse current ranging function needs to be used with a high-voltage signal generator to measure the distance from the fault point to the test point based on the reflected waveform of the fault point.)

It has three test mode of low voltage pulse, pulse current and intelligent bridge, which are suitable for accurate distance measurement of high resistance, flashover, broken wire, low resistance and other types of faults of power cables. Pulse current and intelligent bridge functions are optional and you can choose the required function according to your actual request.

Fully automatic algorithm: low voltage pulse mode adopts fully automatic algorithm, one-click display of the fault distance.

Distance measurement mode: low voltage pulse, pulse current (optional), intelligent bridge (optional).

LCD screen: 4.3-inch high-resolution true color LCD screen, touch screen design, visible in sunlight.

Knob encoder: move the cursor and select the menu, faster and more convenient.

Waveform storage, can view the waveform on it or on the software through computer (optional).

Waveform comparison function, the waveform of the fault cable and good cable can be compared on the same screen.
