초록

This paper deals with a basic study on the development of enhanced stroke collector system for the measurement of lightning current from cloud to ground lightning return stroke. The conventional lightning protection system is based in the premise that any stroke to the protected area must be collected by that system and diverted via a safe path to ground. But it is very difficult to measure the waveform of lightning current in the exactly time and position what we want, because the lightning discharge is occurred irregularly. So, we have designed a lightning cloud simulator and examined the effect of seed voltage on the lightning rod. As a result, it was confirmed that the seed voltage on the lightning rod would be effective to induce the lightning return strokes.
