“…These corridors are located at lateral distance which is the same as at its axis: 0 m, 36 m, 62 m, and 150 m respectively as shown in Figure 6. The result of the research conducted by Mpanga et al showed that the lateral distance was taken as far as 40 meters on the corridor edge with a range of electric fields fluctuating from 10 kV / m (minimum) to 32.38 kV /m (maximum) [12]. In this research, the growth of axis was taken as far as 200 meters to the edge of the corridor, each divided into the corridors A, B, C, and D, i.e.…”

This paper analyses the change of electric field in the proximity of 500 kV extra high voltage (EHV) transmission lines, in the presence of raindrops and dew. The computations were carried out using MatLab software b y solving the electrostatic equations. The analysis depicts that the spatial distrib ution of the electric field strength varies with water drop content along the lateral distance along the transmiss ion line. The peak electric field reduces with the water drop content, whereas the electric field remains the same at around 36 m from the transmission line. Then onwards the field strength increases with the water drop content. At long distances the field strength is not affected b y the water drops. Such variation is highly important to analyse the adverse effects on the insulators used in HV applications. The results are of high significance to a country such as Indonesia where the precipitation levels are generally high in most parts of the country.

“…There are many methods that have been developed to determine the electric field strength under the OHTL. Among them are the quasi-static method [6], the classic image method [7][8][9], the vector magnetic potential method [10], the impedance characteristic equation method [11], the CDM method [12], the Biot Savart method [1], the integral equations method [13], the surface integral equation method [14], the 3D integration method [15], the surface voltage gradient method [16] and the finite element method [13]. However, the currently available methods of calculating the electric field strength under the 150 KV OHTL do not accomodate the layered medium under the OHTL.…”

There have been many methods used to determine the electric field strength under the 150 KV overhead transmission lines (OHTL). Since it is simple and can be used for a homogeneous and multilayer medium, the method chosen for modeling the electric field under the OHTL is the complex image method (CIM). The results obtained show that the electric field strength obtained by the CIM is in agreement with that obtained by Complex Determine Method (CDM). Furthermore, the results obtained from the CIM model fit well with the field data. The OHTL height that must be raised so that the electric field strength under the OHTL will meet the WHO quality standards is 3 m at location A and 2 m at location B. These results show that modelling the electric field under the OHTL using CIM is exellent.

“…Such a mathematical model can be very useful in various real world applications, such as electrohydrodynamic (EHD) pump configurations, electrostatic precipitators, EHD dryers, electrostatic separators etc [5], [7][8][9][10][11][12][13]. Similar studies may be found in bibliography [14][15][16], nevertheless not providing full analytical solutions for the field strength, the potential distribution or the determination of the analytical equations of equipotentials all over the space surrounding the specific electrode sets under consideration.…”

<p><span lang="EN-US">This work presents analytical formulas for the estimation of the electrostatic field in cylinder-plane and cylinder-cylinder electrode configurations. Assuming a predefined potential difference between the electrodes and given their geometrical characteristics, these could be useful for the solution of numerous problems involving such electrode sets. Moreover, the voltage distribution around the electrodes is defined by providing equations either for the equipotentials at a given voltage ratio, or the exact estimation of the potential at any point in the surrounding space. Simplified expressions for critical engineering parameters such as the peak electric field and the field enhancement factor are also given.</span></p>
