DJI Zenmuse L2 LiDAR: A Flagship Sensor for Power Line Inspection

LiDAR technology has become indispensable in the modern electrical industry. During power line inspections, field teams frequently encounter significant challenges including inaccessible locations, hazardous terrain, time constraints, and stringent accuracy requirements for measuring cable distances, detecting damage, and ensuring grid security.

DJI Zenmuse L2, a next-generation LiDAR sensor capable of producing highly detailed and accurate data. This sensor is specifically engineered for mapping and inspection applications, particularly for electrical distribution and transmission networks. When mounted on a DJI Matrice 400 drone, this combination creates a comprehensive inspection system ready for efficient and safe field operations.

High Accuracy and Wide Range LiDAR Sensor

DJI Zenmuse L2 LiDAR sensor delivers exceptional performance with several key capabilities. It can generate up to 240,000 points per second, enabling extremely detailed mapping operations. The sensor offers an impressive measuring distance of up to 250 meters, which can extend to 450 meters on reflective surfaces. With vertical accuracy of 4 cm and horizontal accuracy of 5 cm, it meets the demanding precision requirements for cable and infrastructure inspection.

DJI M400: Intelligent Collaboration Features for Power Lines

DJI Matrice 400 incorporates several advanced features designed specifically for power line operations.

  • The AR Power Line function automatically detects power cables and displays them as augmented reality lines on the remote controller screen, making navigation easier in cable-dense environments such as substations and high-voltage transmission corridors.
  • The Horizontal Rotating LiDAR capability allows the sensor to rotate 360° horizontally and can detect cables as thin as 21.6 mm from a distance of 35 meters. Additionally, the Six-Directional mmWave Radar can penetrate adverse weather conditions including fog, rain, and snow while providing real-time distance and speed detection.
  • Operators benefit from Real-Time Live View functionality, which displays a live 3D point cloud view directly on the control screen.
  • The Wire Path Recognition system automatically identifies main and branch cable paths, allowing operators to simply select the desired path to follow.
  • The Automatic Flight feature enables the drone to follow the selected path according to predetermined parameters while continuously collecting point cloud data.
  • For enhanced safety, the system includes Safe Operation at Line Crossings with early detection capabilities when cable lines intersect and an automatic bypass feature to ensure uninterrupted flight operations.

Real-World Applications

DJI Zenmuse L2 serves multiple practical applications in the electrical industry:

  • It is extensively used for inspection of electricity transmission lines by utility operators and monitoring vegetation that poses potential interference risks to power cables.
  • The system also excels in Right of Way (ROW) mapping for new network planning and topographic surveys for the installation of electricity poles and transmission towers.
