Theoretical and Experimental Investigations of the Surge Response of a Vertical Conductor
Keywords:
EMTP, Lightning surge, Numerical electro- magnetic field analysis, Tower surge impedance, Vertical conductor.Abstract
This paper describes the theoretical, simula-
tion and experimental investigations of the surge response
of a vertical conductor, including the effects of ground sur-
face and without ground surface. One of the authors of
this paper derived the formula of the surge impedance in
case with ground surface and without ground surface. In
this research, these theoretical formulas are examined by
the simulation analysis of the vertical conductor using the
Numerical Electromagnetic Code (NEC-2) as well as the
experimental basis. The arrangement of the current lead
wire in the vertical conductor model to be analyzed here
is verified with the simulation result of the equivalent cir-
cuit model by the Electromagnetic Transients Program
(EMTP).
