Due to the growing demand for line studies for fiber installation, Dielmo 3D has created methodologies that allow obtaining accurate results from LiDAR data.
In this article, we introduce one of the multiple projects carried out from LiDAR data, of more than 2 years of duration, using this new methodology.
The objective of this project is the study and analysis of existing power networks, both in transmission and distribution lines, to detect risk areas where the installation of possible new fiber-optic lines on these structures may pose a safety risk or non-compliance with current regulations.
To this end, Dielmo 3D developed its own methodology, 100% automated, which allows the detection of potential risk, identification of risk typology, measurement and reporting of safety distances (clearances), for all network elements, such as pole inclination, the lowest point of span, the distance between telecom and power cables, etc.
The project is requested due to a clear need: To extend the Fiber Optic network throughout the territory, in the fastest and most efficient way possible. For this, in many cases, it is proposed to reuse existing infrastructures, adding a new FIBER / Telecom line to the network.
Dielmo 3D usually offers its customers one or both of the following products:
In this particular project, our client contacted us for the second case: To obtain a customized product that would allow a detailed analysis of all the key elements of the existing electrical and telecommunications network, as well as to validate if the infrastructure complied with the NESC national security parameters.
In the case of non-compliance, centimeter-accurate detection, measurement, classification, and reporting were required.
Although our client has the technical capacity, to a greater or lesser extent, to carry out the project on their own, for reasons of efficiency, quality, and delivery times, they prefer to delegate the work to a trusted company, capable of developing new work methodologies and specific tools for the project.
In this case, the need for a customized tool that could perform all those calculations and generate all those reports automatically in more than 2600 miles, was fundamental to achieve the project’s response in a timely manner.
This new tool, together with the reliability of the data processing, allowed a complex project with very tight deadlines to result in a successful project with barely any setbacks.
A LiDAR data acquisition has been performed to visualize with centimeter accuracy the electrical network and its environment. From this high-precision point cloud, Dielmo3D has identified and classified all the elements of study for this project, from electrical wiring by voltages, to existing electrical elements in each pole or span (transformers, risers, guy wires, etc).
Once all the elements have been identified and taking into consideration the safety parameters required by the end client, algorithms have been developed for each detected study element and clearance measurements, simple and combined, have been launched to confirm if each span and structure meet or not the requirements.
In the case of non-compliance, the measurement is automatically reported, classified according to the risk, the type of element, and the distance detected (distance between Telecom cable and power cable not allowed, distance from the lowest cable to the ground in the middle of the span insufficient, etc.).
So that the data can be exploited in different fields, the results obtained are generated in different formats according to the needs of the project:
After 2 years of work, the project was successfully completed, meeting deadlines and expectations. All anomalies detected and measurements taken over more than 2600 miles were automatically reported in technical (Excel), visual (PDF) and cartographic (CAD) reports facilitating decision making for the end customer.
But undoubtedly, the best result is the confidence acquired by our customers, who, if in the future requires a new analysis of their network, will turn to Dielmo 3D as their first choice for customization and day-to-day support of their customized products, both for quality and competitive prices.
