With the deepening of drone applications in the power industry, users' requirements for drone and load performance are gradually increasing. The latest Zenith H30T load from DJI integrates zoom camera, wide-angle camera, thermal imaging camera, laser rangefinder, and near-infrared fill light, bringing multiple optimization upgrades and providing a new solution for power inspection operations.

Infrared camera: Do not overlook small hidden dangers in equipment

In power inspection, infrared thermal imaging technology can detect the heating situation of power equipment and ensure power supply safety.

The resolution of the Zenith H30T thermal imaging camera is 1280 × 1024, which is significantly improved compared to the previous generation. In actual testing, even small points of poor contact can be clearly identified by H30T, providing extremely accurate hazard location for power maintenance personnel.

The Zenith H30T is equipped with a temperature sensor and a laser rangefinder, which can help users record environmental temperature and shooting distance data. Through the DJI Infrared Thermal Analysis Tool 3 (DTAT 3), environmental parameter compensation is added for temperature measurement correction, improving the accuracy of temperature measurement.

Zoom Camera: Ensuring Efficiency and Safety for Ultra Long Distance Inspection

The traditional inspection method often requires staff to operate drones to take close-up shots of power equipment, which poses high risks and difficulties in the operation. The Zenith H30T has the ability of 34x optical zoom and 400x digital zoom, ensuring the safety and quality of unmanned aerial vehicle remote inspection operations.

This summer, due to heavy rainfall, power supply equipment in many parts of Guangdong was damaged. In mountainous areas where power lines are damaged, signal obstruction is severe and 4G signals are poor after the disaster. In order to obtain the signal, the staff need to fly the drone higher and farther. However, remote inspections often make it difficult to observe the details of power facilities.

For this purpose, the power supply bureau uses DJI M350 RTK equipped with Zenith H30T for line inspection. With the help of the Zenith H30T high-power zoom lens, even if the drone is far away at the mountaintop, the status of the power equipment can be confirmed, providing reliable basis for developing repair plans and restoring power transmission.

Night mode: Light is no longer an obstacle for night repairs

Power failures occur day and night, and night repairs are often difficult to avoid.

Even at night, the infrared thermal imaging camera of Zenith H30T can provide clear images to help staff quickly locate the fault point. In addition, even in situations where there is almost no light at night, the Zenith H30T can clearly display power equipment details, view tower nameplate information, confirm the location of the fault point, and provide strong technical support for night repairs through near-infrared fill lights and night mode.

Prospect stabilization: outputting stable and reliable images

The stability of drones is crucial for the accuracy of inspections in complex outdoor environments.

The Zenith H30T adopts advanced foreground stabilization technology, which can effectively reduce the shaking of telephoto images and bring stable and clear images to refined power inspection operations.
