| Abstract(in English) | The long-range investigations of the lightning damage mechanism in the microwave ralay stations at the power companies were conducted in many research organizations, and the present lightning protection methods for the stations were based on the results of the investigations. The protection measures show several effects, however they can not be sufficient at present. In the future, when taking the new measures, it is very important to know at what rate the lightning current flows(down)through each part of the tower legs and waveguides in the tower and so on. In this report, we measured the time history of the lightning current which flows through each parts of the equivalent steel tower model manufactured, by impressing pulse voltage on the certain points of the tower. |
