Abstract

The influences of coaxial measuring cables on waveform parameters have been neglected in lightning impulse measurements. This is partly because the tolerable uncertainty for determining the front time T~1~ in the reference measuring system is 3% and the induced influence due to using a long measuring cable is expected to be much smaller than the margin. The authors have suspected the validity of the expectation as a result of experience. This paper proposes an analytical treatment of the impulse response at the end of a lossy measuring cable. Using the proposed technique, the measured parameter errors are compared to numerically evaluated ones and it is confirmed that the two are in good agreement. © 2010 Wiley Periodicals, Inc.
