“…There have been many studies conducted on the overvoltage due to indirect lightning [2][3][4][5][6][7][8]16]. This paper calculates the lightning-induced voltage on the overhead line using the method proposed by H. K. Hoidalen [16], which has been implemented using the EMTP/MODELS.…”

“…Lightning-induced voltages are a major issue for the electromagnetic compatibility and power quality due to the widespread use of sensitive devices connected to the distribution lines. The lightning performance for lightning protection has been studied by many researchers [2][3][4][5][6][7][8][9]. These are mainly focused on the calculation of overvoltage or flashover rate at various configurations of lightning protection system, such as ground wire, lightning arrester, grounding resistance, and etc.…”

-The Korean distribution line currently consists of overhead ground wires (OHGW), overhead distribution lines, neutral wires (NW), and messenger wires (MW). The MW is installed under the NW. The lightning protection system in Korea is focused on OHGW and lightning arrester and the MW are not considered. Therefore, this paper proposes the applicability of MW for purpose of lightning protection. For this, we analyzed the effects of lightning overvoltage according to the existence of OHGW and MW and the grounding conditions of the MW in the Korean distribution system. The grounding conditions of the MW that we took into consideration were the common or separate grounding of the MW and NW. The analysis based on the equivalent circuit of the distribution pole at each condition was performed. The distribution lines and lightning were modeled using the Electromagnetic Transients Program (EMTP). For each of the installation conditions of the OHGW and MW, the various lightning conditions were simulated and analyzed for both direct and indirect lightning. The simulation results showed that, if the OHGW was not installed in the Korean distribution system, the lightning overvoltage could be reduced by the common grounding of the MW and NW.

“…Direct lightning strikes often cause insulation flashover in distribution lines. Lightninginduced voltages are currently a major concern in terms of electromagnetic compatibility and power quality due to the widespread use of sensitive devices connected to distribution lines [1][2][3][4][5][6][7][8]. Therefore, the calculation of flashover rate at specific distribution system configuration is very important for lightning protection.…”

-Because of the random characteristics of lightning, the Monte Carlo method is applied to estimate the flashover rate due to lightning, however, the simulations using previous methods are difficult to both beginner and expert in power corporations. Therefore, this paper proposes the new and easy method to simulate the flashover rate by connection of electromagnetic transients program (EMTP) and MATLAB. The magnitude of a lightning strike is based on a curve measured in the field, while the classification of direct and indirect lightning depends on the striking distance. In a Korean distribution system, the flashover rate induced by lightning is simulated using proposed method. Simulations of the footing resistance according to the existence of an overhead ground wire (OHGW) are performed and the simulation results are discussed. The simulation results are compared with findings obtained with the IEEE Flash 2.0 program.

“…Additionally, the scale-model technique is necessary to measure very fast transients. A scale model study is sometimes carried out for obtaining a surge characteristic such as the tower surge impedance or the lightning-induced voltage on which a numerical simulation gives poor accuracy, or is not established [8][9].…”

Lightning overvoltages due to a nearby lightning stroke, a direct lightning hit, a backflow lightning current caused by ground potential rise or a backflow current flowing from a customer's facility appear on power distribution lines because the insulation level of the distribution lines is relatively lower than that of the transmission lines. However, it is difficult to represent sufficiently the lightning overvoltages in a numerical simulation. A new factor of the scale-model technique for absorption energy analysis of a surge arrester is introduced in the paper. The factor is determined from the voltage-current characteristic and the critical absorption energy of the surge arrester. This paper describes experimental results on the backflow currents using the proposed scale-model technique. The experimental results confirm that the scale-model technique using the proposed factor is applicable to the study on absorption energy of a surge arrester in a distribution system. This paper introduces a new factor of the scale-model technique to make an experiment for analysis taking into account the voltage-current (V-I) characteristic and the absorption energy of a surge arrester. Then, experimental results considering the surge characteristics of the surge arrester by the scale-model technique are described, and it is confirmed that the proposed factor is applicable to lightning surge analyses of surge arresters on power distribution lines. 6T.
