“…In Section 4.3, the results of the K-S test indicate that LD serves better than the normal and Gumbel distributions for all of the values of the sweep voltages, except for 0 V and -150 V. Because of the successful performance of the 3PWD in self-restoring gas-insulated systems [6][7][8][9], LD is also compared with the 3PWD…”

“…In self-restoring insulation systems using air, vacuum, or SF 6 , the type of impulse breakdown voltage distribution is generally assumed to follow either normal or Weibull distribution [6][7][8][9]. Vibholm and Thyregod assessed 4 different impulse breakdown distributions determined by the up-and-down test method: normal, logistic, 3PW, and Gumbel distributions (GDs).…”

“…After analyzing the works of the researchers in [6][7][8][9], in this article, 4 different types of probability distributions are considered to decide on the best-fitted distribution to the present impulse breakdown voltage data: normal, logistic, 3PW, and Gumbel distributions. For the selection of the distribution, parameter estimates are performed by applying the method of maximum likelihood estimation (MLE).…”

“…The most suitable types of statistical distributions that are applied for the evaluation of impulse breakdown data under different experimental test conditions are found [6][7][8][9]11] to fit logistic, normal, Gumbel, and 3PW distributions. Hence, in this work, for the statistical evaluation of a 50% impulse breakdown voltage, these 4 types of distributions are selected.…”

“…For generalization, a further attempt is made to determine the best suited type of existing 3-parameter distributions. From among the existing 3-parameter distributions, 3-parameter Weibull distribution (3PWD) is selected and compared to LD using the likelihood ratio (LR) test, because of its distinct representative feature in gas-insulated systems [6][7][8][9].…”

This paper presents a comprehensive approach to the statistical characterization of impulse breakdown voltage under the effect of a DC sweep voltage. Several goodness-of-fit tests are applied to up-and-down test results obtained in the air-insulated rod-plane gap. Three distributions, normal, logistic, and Gumbel, are compared by means of the Kolmogorov-Smirnov goodness-of-fit test, and logistic distribution is also compared to 3-parameter Weibull distributions using the likelihood ratio test. Logistic distribution is found to be a possible alternative to normal and 3-parameter Weibull distributions.
