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

The purpose of the research is to devise and implement for testing the ability to absorb energy from vibration. The results are obtained from simulating the operating status of small machines. In order to get the mechanical force from the vibrating of the machine by using piezoelectric materials (PZT) It was found that the size of the piezoelectric materials used in each condition affected the energy absorption. There are variables interested in different diameters at 27 and 35 millimeters. The result shows that the dielectric displacement is directly proportional to the force used but is inversely proportional to the size of the cross-sectional area of the piezoelectric material. In addition the ability to absorb energy in one second is 4.51 volts and has a maximum energy of 7.4 x10 -8joules.

Ceramic Bismuth Sodium Samarium Titanate - Barium Titanate at the concentration of samarium 0.04 mol% was preparing by ball mill technique. This research has increased the temperature in the combustion process at different temperatures from 940960 and 970 degrees Celsius for 7 hours. The results showed that firing at different temperatures made the ceramic beads very dense. In addition the study of the crystal structure by XRD technique to study the structure of the ceramic BSNT-BT found that the structure is the same substances in the ceramic group BaTiO3. The results of the study of dielectric properties and ferroelectric properties It was found that the dielectric and P-E hysteresis loops were related and tend to correlate with increasing density with sintering temperature. The mechanical properties of ceramics were tested by measuring the hardness of ceramics at different temperatures with temperatures affecting the changes in various properties of ceramics BSNT-BT.

This research study investigated the structure and electrical effect of the La3+ and Sm3+ co-modified BaTiO3 ceramics with formula Ba1-(x-y)(LaxSmyTi)O3. The concentration of of x was fixed at 0.010 while that of y varied from 0.010 to 0.040. The ceramics are prepared by a solid-state mixed-oxide technique. The phase formation behavior is studied using x-ray diffraction (XRD) The dielectric properties with temperature are broad as wide temperature rang. Results showed that co-modified BaTiO3 ceramic ratio of 0.010 to 0.020 still tetragonal structure where the A-site is disturbed by a group of rare-earth doped. In addition we also found that the dielectric constant increases with ratio of 0.010 to 0.020 and respond to higher frequencies that can be used in the applications circuit with high frequency.
