High voltage laboratory tests and lightning phenomena
Abstract
Attention is given to the similarities and differences which exist between the laboratory long spark and an actual lightning stroke. The feasibility of using simulation to evaluate the consequences of natural lightning on aircraft and grounded structures is assessed. Laboratory test facilities and measuring techniques are reviewed, the main features of the long spark are presented, and the influence rendered by experimental conditions is discussed. The final stage of the discharge is described as it relates to the striking of grounded structures; discharge characteristics upon interaction with a free potential electrode inside the gap are given. It is concluded that the study of RF signals radiated by a laboratory spark could lead to a better understanding of those emitted by natural lightning. It is noted that the striking of grounded structures is satisfactorily reproduced by laboratory tests.
