“…So, the vector of electric field and the current density vector have only z component, and the magnetic induction vector has only φ component [21]. These quantities depend only on time (t) and distances from the conductor axis (r) and do not depend on the coordinates φ and z as shown in [22]:…”

The reliability and service life of power cables is closely related to the cable ampacity and temperature rise in the power cable. In a conductor carries AC current, complex processes may appear, which directly affect the temperature of the conductor surface. So, to keep a conductor in a good state, it is necessary to maintain the conductor temperature in a acceptable value. In this paper, a procedure for measuring the temperature of conductor surface and the corresponding numerical processing of measurement results has been presented. The measurement of the temperature probe characteristics and the temperature measurement on the surface of the conductor, both required the use of certain numerical methods, such as interpolation and fitting of the measured values in time diagrams. The procedure was applied to three copper conductors with different cross section area and one aluminum conductor and the final results are presented graphically, in the form of time diagrams.

In this paper the performance of existing and novel designs of overhead bare conductors with regard to their capacity to evacuate the heat generated by ohmic losses is compared. The effect of both the diameter of strands and the external shape of the conductor on the convective heat transfer capacity are evaluated with a finite element method commercial software for an ACSR conductor with different diameter strands, wind velocities and conductor current, resulting in a design that improves the customary design by around a 7 % of thermal rating.

“…For an overhead transmission line, the maximum temperature it supports is 80C° [4][5][6]. The conductor transmitting 700 amperes at 40C; can transport 1200amperes at 10C°, which implies, from summer season to winter; transmission line capacity can reach the double [4,6,7].…”

<p>The main focus of this paper is a study that empowers us to understand how the temperature variation affects the transmission line resistance and as a result the power flow analysis with a specific end goal to assess losses in the electrical network. The paper is composed of two sections; the first part is a power flow study under normal conditions utilizing the neural network approach while the second investigated extreme learning machine algorithm efficiency and exactitude. Extreme learning machine algorithm has been used to settle several complications in power system: load forecasting, fault diagnosis, economic dispatch, security, transient stability; Thus, we proposed to study this technique to figure out this sort of complex issue.</p>The study was conducted for IEEE 30 bus test system. The simulation results are exposed and analyzed in detail at the end of this paper.
