Inference for Impulse Responses [PDF]

open access: yes
Poor identification of individual impulse response coefficients does not necessarily mean that an impulse response is imprecisely estimated. This paper introduces a three-pronged approach on how to communicate uncertainty of impulse response estimates ...

Input Impedance Characteristics of Counterpoises for an Impulse Voltage Wave [PDF]

open access: yes, 1979
P(論文)Counterpoises act as a sort of electric grounding equipments in power transmission line systems. They are horizontal wires buried in the earth at a depth of about a half meter, and tied to the tower base.

Impulse ageing of polymeric materials

open access: yes, 2011
Impulse over-voltage is a common phenomenon in electric power systems. A switching impulse is created by a switching surge or local fault while a lightning impulse is due to direct lightning strike to high voltage plant such as an overhead line.
