The Induced Charge Test under Thunderclouds Simulation Background
In order to study induced charge under simulated thunderclouds background, a thunderclouds simulation test platform had been built and a measuring instrument of induced charge had been developed. The test platform consisted of a metal disk, whose diameter is 3 meters the change of electric field can be simulated though imposing changing voltage to the metal disk. The slow changing electric field can be simulated by applying the direct-current voltage to the disk and cut it off instantaneously, while the fast changing electric field can be simulated by applying the impulse voltage to the disk. The induced charge can be measured by the measuring instrument under these two methods. The results showed that measuring instrument of induced charge can realize measurement of simulated fast changing and slow changing electric field. So the measuring instrument can be applied to the study of induced charge.
