“…However, there was an error between the calculated field from the proposed equation and the simulated one using finite element method (FEM). Therefore, a correction factor called (β) was proposed by [1] for correcting this equation. This factor was based on three variables i.e., relative permittivity, barrier location and barrier thickness.…”

“…In addition, AI optimization techniques are widely used in solving non-uniform field problems especially at high voltage (HV) applications [3]. One of the most non-uniform field problems in the HV is the using of the transverse layer of a Dielectric Barrier (DB) in the field gap configuration [1], [4], [5]. In recent years the air gap field strength is increased by inserting DB at optimum location between the HV electrodes.…”

“…In addition, different mathematical models were presented to describe the field distribution in the case of the existence of DB in the field gap [4], [5], [14]. A new mathematical equation for simulating the non-uniform field in the case of using DB along the gap configuration was given by [1]. But the maximum error from this equation reaches 2.74 percent, especially at the 30 percent of the gap length from the HV electrode.…”

In this paper, a proposed moth-flame optimization (MFO) technique has been investigated for obtaining an accurate simulation of the non-uniform electric field represented by a needle-to-plane gap configuration. The needle electrode is connected to the high-voltage (HV) terminal, while the earthed terminal is connected to the plane electrode. In addition to the non-uniformity of the field, a transverse dielectric barrier has been presented and investigated along the gap with a different thickness and location. The MFO works to optimize the error given by a numerical equation published before for calculating this field problem in the presence of a transverse barrier. This numerical equation was based on a correction coefficient called (β), which is dependant on three values, relative permittivity, barrier location, and barrier thickness. The MFO is working to minimize the error given by β using two new optimization factors in the β equation. To ensure the accurate validation of MFO with a minimum error for field problem simulation, various artificial intelligence (AI) optimization techniques have been compared with the MFO obtained results. The comparative study shows that MFO is more effective, especially at 30% of the gap length from the HV electrode which represents the region of highly non-uniform field along the gap configuration. The numerical results of the field simulation that are held by different types of AI techniques are compared with those obtained from the accurate simulation results using the finite-element method. The value of the error between the numerical and simulation results shows that MFO is the most effective optimization techniques that can be used in the numerical equation to obtain the best value of the correction factor. With MFO, good agreement has been reached between the proposed numerical equation and the accurate simulation values of the electric field problem.

In this study, the effect of electrode configurations on breakdown performances of polyethylene terephthalate, presspaper and styrene-butadiene rubber/natural rubber blend is investigated with the considerations of electrode area and field enhancement factor. Cylinder-cylinder, spherical-cylinder and point-cylinder electrode configurations are used for breakdown experiments and the measurements are taken according to the rapid-rise method. Characteristic breakdown voltages of the materials are obtained for each electrode configuration by performing Weibull analysis on experimental results. Based
