“…The study in reference [25], on the first hand, despite its relative accuracy in evaluating the MFs, still has its FEA based on meshes with triangular elements, unlike the tetrahedral elements used in this study, which have more accurate representations of complex 3D geometries (i.e., stranded transmission lines). From another side, the work in reference [26] took into consideration only two static models for overhead TLs (i.e., 161 kV and 330 kV), such that MFs are then calculated by using GetDP 3.4.0 software. This procedure hence reflects a lack of flexibility, when considering other types of overhead TLs, unlike the strategy proposed in this work.…”

This paper aims to design the fundamental basis for an Unmanned Aerial System (UAS)-driven, remote, and non-invasive current sensing application. Using the COMSOL software, the methodology presented here consists of the Computer Aided Design (CAD) for stranded Transmission Line (TL) geometries composed of 7 to 91 sub-filaments and discretized via tetrahedral-element-based meshes. The radiated Magnetic Field (MF) around each TL is then solved by means of Finite Element Analysis (FEA) after selecting the proper materials for TLs under the coil geometry analysis study. For each TL, all resultant MFs’ norms are presented as tabulated data, with respect to the inducing currents. Eventually, the complex mathematical model needed to evaluate these MFs, radiated around stranded TLs, is surpassed by the scalable models designed through this study. The min/max MFs radiated around each TL resulting from the min/max injected current values are hence obtained. This would serve in the accurate choosing/positioning of magnetic-based sensors in UAS applications, reliably. Additionally, related future works are concretely presented.

“…Adegbola et al [6] presented the electrical field emissions analysis for the 330 kV and 161 kV transmission lines. Indulkar and Ramalingam [7] gave an estimation of voltage, current and power at the ends of the transmission line using the Newton-Raphson method.…”

Transmission models are dominated by lumped models, which describe the time dependence of transmission potentials (temperature, current and voltage). The space counterpart is not incorporated into the lumped model. To fill this gap, the present work proposes a distributed or coupled system of thermal and power equations, which depend on both space and time. The coupled system of equations were developed on the balance of thermal and power fluxes around a control volume representing the transmission lines. The Finite Difference Method is pivoted on the Crank Nicolson technique is used to solve the coupled system of equations. Transmission percentage losses ranged from 0.03 to 0.06%, which is consistent with the 5% recommended by the American Transmission Company. In addition, the simulated model results corresponded to field data obtained from the Uganda Electricity Transmission Company Limited (UETCL) on the Bujjagali - Kawanda transmission line. The coupled model system is useful for the simulation and estimation of the power losses in transmission lines respectively and could be implemented in other transmission lines.
