Spot testing

Our online continuous monitoring solutions provide real-time visibility of the insulation condition, allowing early detection of defects to schedule preventive actions analyzing the activity.
‍
The system collects data from different types of sensors: PD, temperature, humidity, pressure & current. All data is analyzed in our AI PDEye platform, generating high reliability alerts automatically connecting to company's asset management system.

From blackout to Partial Discharge Monitoring at Madrid airport

A one-hour blackout at Madrid-Barajas Airport revealed insulation defects in a newly installed 45 kV cable. Partial Discharge (PD) Monitoring using BlueBox Technology identified critical faults, guided targeted repairs, and restored power reliability in one of Europe’s busiest airports.

Securing the grid with smart DLR sensor location

A critical part of a line, shielded from direct wind, overheated despite favorable forecasts. A Dynamic Line Rating (DLR) sensor placed on that segment revealed the real-time risk, enabling timely action to maintain grid safety.
