Abstract
AN apparatus which produces in the laboratory a lightning-stroke closely resembling in its effects the natural phenomenon (for example, lengthwise splitting of full-sized wooden poles) is described by P. L. Bellaschi. The test piece is ‘flashed over’ with a steep fronted impulse from a three million volt generator. A heavy current generator is immediately afterwards connected to the test piece by means of a micro-second switch, thus enabling the full low-voltage discharge to follow the high-voltage breakdown across the piece tested.
