What fails, located before it stops your line or your plant.

Drone thermography from Salamanca across Spain: inspection of high-voltage lines, substations and photovoltaic plants. A clear report: where the hot spot is, which element it is and how severe it is.

What we do

Three services, one clear report

Drone thermography and LiDAR for electrical infrastructure and solar energy.

High-voltage lines

Every tower, inspected from the air

A flight along the line with thermal and visible cameras. Every hot spot is linked to its tower, its phase and its element.

  • Location by tower, phase and element (clamps, jumpers, insulators…).
  • Visible and thermal images together, with real measured temperature.
  • Classification by severity to prioritise the repair.
  • No outages or shutdowns: the line stays in service.

ThermalSubstation thermography with a hot spot on the transformer

Substations: the same flight shows each element of the installation in thermal, such as the transformer, to locate hot spots without touching anything.

Hot spots are not seen… they are measured

A module with an active bypass diode or a defective cell looks normal to the naked eye. The thermal camera gives it away.

  • Detection of hot spots, bypass diodes and strings with issues.
  • Every anomaly located by module, with visible and thermal photo.
  • Severity Medium / Serious / Critical to decide what to repair first.
  • Report with table, images and location, ready for your O&M team.

To the naked eye the module looks fine. In thermal, the hot cells glow: each one is located, photographed and classified.

LiDAR

The terrain and the line, in three dimensions

A LiDAR flight returns millions of points with exact coordinates. From them come measurements that would take weeks in the field.

  • Point cloud classified by type: terrain, vegetation, structures and conductors.
  • Distance from vegetation to the conductors and line sag.
  • Digital terrain model, contour lines and profiles.
  • Surveying and construction monitoring with data that can be compared over time.

Equipment and qualifications

What I work with, and what backs it up

Latest-generation professional equipment and up-to-date documentation to fly at any installation.

How I work

From request to report, no surprises

01

Planning

Study of the area, flight permits and a schedule agreed with the owner.

02

Flight

Thermal, visible and LiDAR capture under suitable conditions for each type of measurement.

03

Analysis

Review of every image and classification of the anomalies.

04

Report

Clear delivery: location, element, severity and images of each point.
