DJI M350 RTK Tethered Drone Wind Turbine Lightning Protection Resistance Detection Device

Wind Turbine Lightning Protection Resistance Detection Device

Project Background

With the continuous increase in the size of wind turbines, the likelihood of being struck by lightning has also grown. Lightning strikes may damage the control systems, electrical equipment, blades, and generators of wind turbines. It is estimated that lightning strikes account for 80% of wind turbine insurance claims, and lightning-caused losses account for 60% of total blade losses. On average, each wind turbine suffers blade damage due to lightning strikes once every 8.4 years. Calculated based on a 20-year lifespan for wind turbines, the total number of blade damages caused by lightning strikes is 2-3 times.

Solution

The DJI M350 RTK is equipped with a retractable contact copper mesh, which flies below the blade tip and makes contact with it. An automatic retractable winch is used, with one end connected to ground detection instruments and the other end connected to the copper mesh. This is used to test whether the blade tip is conductive and measure the resistance value.

Required Equipment

1. DJI M350 RTK / DJI M300 RTK

2. Retractable Contact Copper Mesh

3. Automatic Cable Reel Winch

4. Detection Instruments

Nanjing Airfly Electronics Technology Co., Ltd. (Airfly Tethered) was established in June 2018. It is a globally leading full-link, all-scenario solution provider of tethered systems, always focusing on the applications and solutions of tethered scenarios.

We focus on the R&D, production, and sales of tethered drones and related products. Through the innovative “Tethered Supermarket” platform, we provide modular solutions for global customers. Customers can precisely select online:

· Ground power stations (AF-G series),

· Aerial power modules (A unregulated and WF regulated series),

· Tether winches (AF-T series), and

· Scenario-based system kits (SF series),
to build customized tethered systems independently.

Backed by top university technical teams such as Nanjing University and Southeast University, we hold core patents for high-power tethering systems (5–60kW), fully compatible with DJI M30 / M350 / M400 / FC30 / FC100 and other industrial drone platforms.

We achieve over 24 hours of continuous endurance, centimeter-level hovering accuracy, and stable deployment in extreme environments.

Our solutions have been successfully applied in key scenarios such as:

· All-weather monitoring in Middle Eastern oil fields,

· Disaster emergency communication in Southeast Asia,

· Border security patrols in Europe,

serving over 80 international customers across more than 30 countries and regions.

As an important participant in the low-altitude economy, we continuously integrate R&D, business matching, and global service resources, aiming to simplify the deployment process of tethered systems.

Visit the Airfly Tethered Supermarket now to experience the one-stop solution of "Selection - Configuration - Delivery", empowering intelligent upgrades in fields such as power inspection, emergency communication, and security monitoring.
