Solutions for predictive maintenance and fault detection on medium voltage outdoor and indoor power lines

Pole Discoverer is a detector of permanent and transient faults for medium-voltage power lines with rated frequency in the range between 50Hz-60Hz. Has been designed to be easily and quickly installed on indoor and outdoor peripheral lines, lacking of any other protection device. Installation does not require direct connection to the grid. It is capable to recognize single-phase-to-ground breakdowns, phase-to-phase short circuits and monitor line voltage presence. Pole Discoverer unit is battery-powered, therefore intended for temporary use with the possibility to remove and re-install the device elsewhere.


No direct connection to power line required.

GPS/GSM alarm available for fault occurrence and voltage absence.

Through dedicated Android App

Compatible with any MT line geometry, indoor and outdoor
