Abstract

Recently, the simultaneous fault of two lines by winter lightning on the coast of the Japan sea and the damage of ground wire become new serious problems. The observation of lightning current is important primary step to solve these problems.
By the way, it was necessary to use large-scale equipments such as commercial power source and shed for usual observation of lightning.
So we have developed “lightning wave memory” composed of Rogowski coil, digital memory and data storage device.
This device is light and can be easily installed on the transmission tower or the ground wire, so we can use it in any observation places.
Moreover, 40 lightning current waveforms with the time, peak current, porality and energy are memorized automatically by it.
Many lightning current waveforms were already obtained by this divice.
In this paper we deal with the structure of a developed lightning wave memory and the observation results by using this device.
