Statistical analysis related to impulse tests for self‐restoring insulation
Yoshio Komori · IEEJ Transactions on Electrical and Electronic Engineering · 2008
Abstract For dielectric tests with impulse voltage, some statistical methods with the step‐up procedure have been recently proposed. In the present paper, the methods are reconsidered from the viewpoint of statistical independence concerning disruptive discharges. As a result, modified methods with the step‐up procedure or with the up‐and‐down procedure are proposed for self‐restoring insulation, and it is shown that they have good properties in the maximum likelihood estimation for the mean and the standard deviation of a normal distribution.
