Protocol for contactless electric current sensing, processing, and storage using a drone-integrable sensor

Here, we present a protocol for implementing a contactless, drone-mounted current sensor to measure and record electric current norms in overhead transmission lines. We describe steps for designing, fabricating, and assembling the printed circuit board (PCB) and programming the Arduino Mega 2560 as the data processor. We further outline the integration of MATLAB scripts for graphical visualization of the sensed currents, ensuring efficient data interpretation. This protocol enables accurate laboratory-based measurements up to 98.3% under high-distortion test scenarios. For complete details on the use and execution of this protocol, please refer to Osmani et al.¹.
