Fixing short circuits

Submit an application

The short circuit indicator allows you to reduce the time to search for short circuits on power lines with a solidly grounded neutral, as well as phase-to-phase short circuits on lines with an isolated neutral, and send a repair team immediately to the place of the malfunction, thereby reducing the time to eliminate it.

This is especially true for long and branched lines. img. 1

Sampling frequency: 2.4 kHz
Current setting - 10-10000 A
Time setting - 0.5-500 ms
Oscillogram depth – 0.6 sec. ( 0.2 sec before event, 0.4 sec after event)
Fixed peak current values - +/- 10 kA (on request, it is possible to expand the measurement range)
Current drop to 0 message

When a short circuit occurs, the program determines the network segment between two groups of devices and informs the operator of the current strength and phase (s) in which the short circuit occurred.

If there are many taps, the fault location device in the substation cannot accurately calculate the location of the fault. By installing the indicator at the beginning of the soldering, we solve this problem. Img. 2.
