“…Equation 1.5 enables prediction of the breakdown behavior of electrodes with different areas from the Weibull distribution obtained from the breakdown distribution of a single electrode. This approach has been taken in many publications [9,15,16,[34][35][36][37][38][39][40][41][42][43] and most recently confirmed in [7] for LAr. The Weibull distribution of equation 1.3 results from the power-law scaling form chosen in equation 1.1.…”

A: As noble liquid time projection chambers grow in size their high voltage requirements increase, and detailed, reproducible studies of dielectric breakdown and the onset of electroluminescence are needed to inform their design. The Xenon Breakdown Apparatus (XeBrA) is a 5-liter cryogenic chamber built to characterize the DC high voltage breakdown behavior of liquid xenon and liquid argon. Electrodes with areas up to 33 cm 2 were tested while varying the cathode-anode separation from 1 to 6 mm with a voltage difference up to 75 kV. A power-law relationship between breakdown field and electrode area was observed. The breakdown behavior of liquid argon and liquid xenon within the same experimental apparatus was comparable.

“…Statistical methods such as normal distribution, exponential distribution, logarithmic distribution and Weibull distribution are used to analyze and evaluate the failure data of materials. Among them, the Weibull distribution function is widely used for the reliability analysis of products associated with failures because it is possible to determine the failure modes in the early, constant, and wear out failures by using the scale parameter and shape parameter [26,27]. The following is the formula for the two-parameter Weibull distribution function [28].…”

Demand and need for the application of high voltage direct current (HVDC) are increasing because of high capacity and long-distance transmission. Research on polypropylene (PP) that can increase the operation temperature compared to existing insulation is constantly being considered. This study aimed to evaluate the electrical performance and estimate the life of HVDC application of PP. In this study, a DC V-t characteristic tests were conducted on three types of PP sheets at a temperature of 110 °C. In addition, a life estimation formula based on the electrical stress was derived and the electrical performances were evaluated. The experimental results show that the life exponent of material mixed with block copolymer, homo polymer and high density polyethylene (HDPE) was 23 and the electrical performance was 17% better than block copolymer, thereby demonstrating the reliability and electrical performance for application of HVDC.
