“…Upon measuring an electric field, the presence of high-voltage lines in the surrounding area may be detected using the relative intensity of the measured electric field. Several methods have been proposed to obtain electric field measurement [7][8][9][10][11][12]. The most common method involves the use of a dipole antenna [8].…”

When a drone is used for inspection of facilities, there are often cases in which high-voltage power lines interfere, resulting in the drone being caught or falling. To prevent this type of incident, drones must be capable of detecting high-voltage power lines. Typically, a strong electric field is formed around the high-voltage lines. To detect the electric fields around high-voltage lines, this study proposes an electric field sensor that may be integrated within the body of a drone. In a laboratory environment, a voltage of 25 kV was applied to an overhead line, and the induced voltage in the proposed sensor was measured at various electric field intensities. Over an electric field range of 0.5 to 10.1 kV/m, a voltage of 0 to 0.77 V was measured with each proposed sensor. In addition, the electric field and the voltage induced in the sensor were measured in a real-world railway environment with overhead lines. Under these conditions, the proposed sensor has the compensated value of 4.5 when the measured electric field was 4.05 kV/m. Therefore, the proposed sensor may be applied in drones to measure large electric fields and to detect the presence of high-voltage lines in its vicinity.

“…Additionally, they are susceptible to operational issues that compromise their applicability with additive external circuitry (e.g., advanced sensors, smart switchgear, etc.) [14]. Also, the initial reliance of conventional grids on legacy systems, such as Current Transformers (CT) and Voltage Transformers (VT) for measuring applications, in turns poses additional challenges in front of any advanced metering infrastructure's future implementation.…”

Smart grids yield in an efficient energy distribution, driven by advanced grid management and diverse technologies' integration. For instance, the remote monitoring of transmission lines, facilitates the development process of conventional electrical networks into smart grids. One form of such remote monitoring applications can be actuated by means of a drone, which carries an embedded intelligent sensor. These drone-based applications referred to as Unmanned Aerial Systems (UAS), thus allow an instantaneous surveillance of the actual status of transmission lines, remotely. Accordingly, this paper presents an experimental setup of an "all-optical" electrical sensor, confronted with different forced voltage/current (V/I) levels, in order to test its feasibility for future applications in drone-controlled, electric grid monitoring processes. After analyzing different measurements' outputs, and comparing them with reference values outputted by reference V/I sensors, the resulting deviated errors are tabulated and justified. Furthermore, the exploration of the studied sensor's pros and cons, and by taking into consideration the space/weight restrictions that a drone-based application obtrudes, related future work is suggested.
