Abstract

This paper describes characteristics of electric field waveforms associated with multiple-lightning discharges. The electric field measurment system. consists of hemi-sphere antenna 30 cm in diameter. integrator and data acquisition device. The frequency bandwidth is from 200 Hz to 1.56 MHz, and the sensitivity is 0.96 mV/V/m. The detected electric field signal is digitized every 500 ns with the resolution of 12-bit and the length of 2 kilowords and is registered at a personal computer. Also parameters of the electric fields associated with multiple-lightning discharges are ststistically analyzed.
