Endesa, Through its subsidiary e-distribution, it is undertaking a revamp of its high and medium voltage overhead lines during the summer with the aim of anticipating any imperfections or sensitive points that may occur in these facilities and preventive actions. doing. To do this, the company is using the latest technology, which is why it is investing more than 750,000 euros across Andalusia.
in the province Seville, Endesa is reviewing 1,407 km of high voltage line and 2,310 km of medium voltage. To do this, Endesa’s technicians are using the latest technology, using helicopters cameras with thermographic vision and cutting edge technology lidar, And as a novelty this year, a 4K video camera and 150-megapixel photography have been included, according to the company in a press release.
review in helicopter It aims to detect anomalies that may affect the proper functioning of facilities and continuity of power supplies, hence the technology installed in helicopters.
On the one hand, the helicopter’s thermographic cameras allow inspection of the network with infrared cameras, to find out if there are any elements whose temperature is higher than normal. If a discrepancy is found, the coordinates of the “weak point” are recorded and the mechanism to correct it is automatically activated.
In addition to this technology, Endesa has lidar technology (Light Detection and Ranging) – Detection by Light and Distance – which combines technology GPS with laser sensor and allows creating three-dimensional maps and mapping power lines. This tool simultaneously provides information about both the relief of the terrain and the vegetation that covers it, which is very useful for creating high-resolution maps of forest areas and planning forest clearing operations.
This content with images of 4K cameras To record all inspections of high voltage lines and towers, to be able to analyze in detail the visions made later. In addition, Endesa technicians are sometimes using drone In their reviews, a technique that has been implemented since 2012 in Seville and throughout Andalusia. These instruments are equipped with high-resolution cameras that allow images of lines to be captured and are particularly useful for checking infrastructure conditions in areas that are difficult to access without disrupting supplies. Drones also make it possible to verify the width of security corridors that act as firewalls.
Precisely these corridors are another part of the preventive actions which are carried out between the months of October and May in coordination with Endesa. Andalusian government, and includes cutting down vegetation and preventive pruning near power lines. In this way safety corridors can be opened under high, medium and low voltage networks, which makes it possible to avoid power supply incidents and reduce the risk of fire. Harvesting and selective pruning are carried out in accordance with the norms laid down in national and regional regulations, which establish periodicity based on the growth calendars of different species.
