Electrical Infrastructure Inspection in the Azores

EDA - Electricidade dos Açores
Energy Distribution

Overview

EDA faced unique challenges in maintaining the power grid across the Azores islands, with rugged terrain and adverse weather conditions. HP Solutions developed a customised solution using high-precision drones for power line inspections.

The Challenge

The Azores’ geographical characteristics make traditional inspections extremely difficult and dangerous. Access to many areas is complicated, and weather conditions do not always allow conventional work. A solution was required that could overcome these obstacles.

The Solution

We implemented a drone inspection system equipped with high-resolution cameras and thermal sensors, adapted to the specific conditions of the Azores. The drones can operate in difficult terrain and provide detailed data on the condition of the infrastructure.

Implementation

1
Aerial inspection of power lines in rugged terrain
2
Use of drones resistant to adverse weather conditions
3
Capture of detailed images and thermographic analysis
4
Identification of defects and critical points
5
Detailed reports with precise GPS location
