The step propagation of negative upward leaders in positive upward lightning has been analyzed using lightning current waveforms and optical images. We observed upward lightning in the coastal area… (More)
Negative upward lightning flashes from a high structure in winter were observed by a current shunt and a network of VHF receivers, slow antennas and fast antennas on the coast of the Sea of Japan.… (More)
The mechanism of the guidance effect of laser plasmas on electrical discharges has been studied. A 45 J CO2 laser pulse produces many spherical plasmas over a gap of up to 2 m, and the laser-guided… (More)
The authors have examined over a period the basic characteristics of discharge when an open wire fitted as an overhead ground wire is located near a tree, to clarify the attachment manner in which… (More)
SUMMARY Recently, wind power generation systems have drastically increased in Japan. As the increase of the wind power generation systems, outages of these systems by lightning have also increased… (More)
There are many cases where trees grow around power system equipments uch as transmission lines and distribution lines in Japan. For developing better lightning protection measures, it is essentially… (More)
