FRTU(Pad-Mounted)
Installed on 22.9kV V-Y underground distribution lines. Reduces fault detection time by monitoring distribution line data in real time, minimizes outage area and duration by isolating the faulted section and restoring healthy sections by remote control, and improves power quality through distribution line information management.
A dedicated catalogue for this model is in preparation. The general catalogue covers the product.
