TLDR
In this article, a method is proposed for determining the correct settling level of the step response to reduce the great uncertainty in the evaluation of the rise time, which proved to be effective for three different types of impulse dividers.Abstract:
The expression of the transfer characteristic of a HV impulse divider by a limited number of response parameters is considered. The response parameters under consideration for introduction into the revised standard for HV impulse tests are summarized, and the errors in the evaluation of the response time, and time standard rise time, are discussed. A method is proposed for determining the correct settling level of the step response to reduce the great uncertainty in the evaluation of the rise time. The method proved to be effective for three different types of impulse dividers. >read more

Transfer Behaviour of Linear Systems and Convolution
TL;DR: If the transfer behaviour of a linear system is known in the time or frequency domain, its output voltage can be calculated for any input voltage using the convolution theorem, which opens a variety of possibilities to analyse and optimise high-voltage and high-current measuring systems and their components without expensive experimental investigation.
