The UNKSI is intended for use as technological equipment when performing repairs of production wells and provides control over the current resistance parameters of the submersible cable and the electric submersible pump (ESP) during the descent of the submersible equipment.
The device provides automatic monitoring and allows to quickly register and notify in a timely manner when the connection of the Y-winding is broken or when the insulation resistance of the cable to ESP decreases.
If resistance drops below the threshold value that is set in advance, the UNKSI produces an audible alarm at the work site.
Capabilities:
- Wireless configuration;
- Adjustment of the insulation resistance threshold;
- Adjustment of the measurement interval;
- Automatic output voltage releasing;
- Audible alarm;
- Possibility to operate as the standalone device
Design features:
- Quick and easy installation
- Extended operation from the battery
- Wide range of the ambient temperatures.
