“…On the figure, H=16m is an overall height of the powerline tower; W=6m is a width of each traverse; h 1 =12m is a height of the upper traverse; h 2 =8m is a height of the lower traverse. In addition to the parameters shown in Figure 1, we define d=1.02m as a length of the insulator and R min =4m as the minimum distance at which the UAV is not exposed by electromagnetic effects from power lines [8,9].…”

Corona discharges that occur on the conductive elements of power lines are serious problems that can lead to failures in the power system. Corona discharge produces ultraviolet (UV) radiation, which can be detected using special UV sensors. One way to automate inspection of the corona discharge is using of autonomous unmanned aerial vehicles (UAVs) equipped with UV sensor. At the same time, the trajectory of the autonomous UAV flight should be built taking into account the spatial and geometric features of the inspected power lines, as well as the requirements for the gathered data. This work describes a new method for autonomous UAV trajectory planning. The trajectory is planned in accordance with the spatial and geometric characteristics of the inspected powerline, peculiarities of the powerline damage type and in accordance with the quality requirements for the gathered data (representativeness, sample size, unification of the gathering procedure). The trajectory planning method and UV image gathering were simulated in Blender software. As a result, by the fully automated data gathering process, we collected a representative dataset of 200 images in UV spectrum for one lattice tower and two simulated discharges with 326 manually segmented corona discharge areas.

“…On the one hand, the reason is that the actual ocean current electric field signal is close to the nanovolt level, and it is difficult for the laboratory to provide a stable signal source. On the other hand, in the test environment in the onshore laboratory, it is impossible to filter out the high-frequency interference caused by the seawater, so there is more and more complex electromagnetic interference than the background electromagnetic noise of the ocean [23], which makes the extraction of weak current signals more difficult. However, as an intermediate environment linking theoretical simulation and ocean testing, the importance of building laboratory simulation experiments is self-evident.…”

Expendable current profiler (XCP) is one of the most vital devices detecting ocean currents. Compared with other methods, the expendable feature makes trials with XCP much faster and more hidden, while the accuracy of XCP is considerably influenced by electromagnetic noise all around. Aiming at researching the influence and reducing the noise, this study carried out laboratory simulation experiments. The designed laboratory experiments mainly have a self-developed rotation gear, an XCP prototype, a plastic flume, and two copper plates as power. Firstly, these experiments analyzed the main sources of electromagnetic noise for XCP detection. Secondly, we built a noise simulation environment and conducted XCP detection experiments under different noise in the flume. The data obtained by XCP were transmitted to the computer to be stored and processed. The results show the internal noise impact on XCP is significantly less than the external. For an excitation power of 1 mV, the offset of theoretical and actual data brought by internal noise is 12 times smaller than external and can be corrected.
