“…Aiming at development of lightning risk assessment for power distribution systems, we examined a lightning risk assessment method for power distribution lines based on calculation of direct lightning occurrence rate in consideration of surrounding structures and distribution line density [4,5], and a method for lightning risk estimation for customer appliances [6] based on lightning surge characteristics of power distribution-customer-communication network [2] (in this study, these components are called the low-voltage distribution system). As a result, it was clarified that quantitative estimation of the influence of surrounding structures (i.e., customer houses, buildings, transmission lines, and other high structures) is important for assessment of lightning risks in power distribution systems.…”

Recently, concept of the lightning risk management has been proposed for the minimization of damages caused by lightning. In distribution systems (power distribution lines, low-voltage distribution lines, telecommunication lines, and customer appliances), lightning protection measures based on the lightning risk management are effective since the number of facilities is enormous. In this paper, for the establishment of lightning risk management method of distribution systems, we expressed the lightning risk assessment method of distribution systems and examined the influence of arrangement of customer house on the lightning risk values of power distribution lines and customer appliances.

With the progress of the information-oriented society, telecommunication lines are often installed on concrete poles along with power distribution lines. When a lightning stroke hits a distribution pole, the lightning current flows also through the telecommunication line in addition to the concrete pole and the ground wire. And, it is easily estimated that the existence of the telecommunication line reduces the currents through the concrete pole and the ground wire, and thus, reduces the voltage across the insulators to support the phase wires. However, its quantitative study has not yet been carried out.Considering the above, we have measured the surge impedance matrix of an actual-scale test distribution line equipped with a telecommunication line. Using this result, a method to model the distribution line system with the telecommunication line for lightning overvoltage simulations is proposed in this paper. Simulation results obtained by the proposed modeling method are compared with field-test results, and good agreement is obtained.
