finding area threatening vegetation using drones and drones

What are the standards for passage of overhead transmission lines using green spaces?

overhead lines (VL) transmission are provided with technical services aimed at their preservation. There are log books in which to record the results of inspections.

determine the area of threatening vegetation using drones and drones

One of the factors that you notice upon inspection, is the appearance of threatening the integrity of the wires of the plants. Trees tend to grow, in some cases quite quickly. In the construction of power lines for laying overhead line in the territories of forests are cut down the clearing of a fixed width. During the operation the size of the rides are subject to exposure by cutting down trees that have grown outside of the clearing, threatening to fall on electrical wires, limbing and clearing bushes. Clearing can occur on several overhead lines at the same time. In recent years increasingly used the definition of square-threatening vegetation using drones and UAVs.

to prevent damage To overhead line vegetation regulations specified in the Regulations for electrical installations. So for transmission lines with voltage up to 1 kV with self-supporting insulated wires of the standards given below:

  • cutting of glades in the forest are not necessary;
  • is executed felling of individual trees that pose a threat to the integrity of the wires.

For transmission lines with voltage up to 1 kV with non-insulated wires specify the following:

  • clearing in the forest and gardens are not essential;
  • distance when the arrow of the SAG from power lines to trees and shrubs with a maximum deviation of the latter should be equal to or exceed 1 m.

For transmission lines with voltages above 1 kV up to 750 kV rules are:

  • cut down the clearing in the mandatory;
  • clearing width is calculated according to the formula or taken from the table values according to vegetation type, and the voltage VL.

for Example, for overhead lines with a voltage of 750 kV, the minimum horizontal distance between the wires and the trees is 8 m.

Review, don't spread the greens to a dangerous size, is engineering staff annually or as needed. Dimensions are checked from the wiring to overgrown and the condition of the wires in the places of the alleged contact with the knots and branches of trees. Cutting down plants that threaten to damage power lines and limbing subject to registration in the passport of VL.

What are the advantages of finding area threatening vegetation using drones and drones?

UAV - unmanned aerial vehicles - are important service lines. This is due to ease of use. Flying at a low altitude (500 meters) along the alignment line, they take pictures of the area high-precision equipment. They don't need roads along the transmission line, and the picture resolution allows you to see fine details. Software processing which transmitted the pictures and other information coming from drones, gives information about the location and area of dangerous plants.

Specialists of the company LLC "Guild Engineering" worked out the methods of inspection of overhead lines using unmanned aerial vehicles. On plans that include customer surveys, clearly visible as the glades and trees that are growing at an unacceptable distance from the wires. Work with UAVs is performed with a high speed that is determined by technology of operations.
