Design of high voltage insulation dielectric strength testing

Abstract

This research is presented by the designing and constructing test package that are divided into three types; the liquid insulator, solid insulator and gas insulator. These materials are provided by in country in order to construct the test package for the results of expected to have at least error. This leads to reliability and validity in this study. The design of the liquid insulator of test package was conducted by the standard IEC 156 in which the material tested used oil transformer. Additionally, its solid insulation was the range of catching objects and adjusting using the sheet of bakelite. Furthermore, its gas insulation used acrylic was consisted of gas inside oxygen of pressure at 2 Bar. Three types of test could be supplied AC high voltage to test package causing of breakdown via insulators. After that taking note, the value of breakdown was the liquid insulator of test material at 29.86kV, its solid insulator at 36.32kV and its gas insulator (oxygen) at 48.40 kV
