Abstract

Abstrak Sistem pentanahan merupakan salah satu bagian sistem proteksi. Kinerja sistem pentanahan dipengaruhi oleh ketepatan fungsi elektroda pentanahan, karena elektroda pentanahan merupakan komponen utama dalam sistem pentanahan. Untuk mengetahui kinerja yang baik dari sistem pentanahan diperlukan pemodelan elektroda menggunakan pendekatan analitis dan teknik simulasi numeris. Dalam paper ini akan disampaikan review dari metode yang digunakan untuk memodelkan elektroda pentanahan, sehingga bermanfaat untuk proteksi sistem.Hasil review menunjukkan bahwa metode yang paling cocok untuk pemodelan elektroda pentanahan adalah finite element modelling. Kata kunci: elektroda pentanahan, sistem pentanahan, sistem proteksi

Abstract

Paper impregnated oil (paper-oil insulation) is used as insulation material in transformer. The water in transformer appears as a consequence of oxidation process of the paper-oil system and atmospheric air penetration into the tank. High voltage testing is used to test paper-oil insulation with different water content to examine its breakdown voltage. Three conditions were used in this research, which are initial condition, the condition after heating up to 700C, and the condition after cooling down at room temperature for 2 x 24 hour. The result of high voltage tests shows that the water content can decrease the breakdown voltage and the dielectric strength of paper-oil insulation. The heating-cooling process reduces the water content of oil insulation and therefore increases the breakdown voltage and dielectric strength of paper-oil insulation.

Abstract

Flashover is a disorder condition that occurs in the form of sparks appearing between insulators or electrical component of high voltage. This can occur due to insulation failure of the high voltage system. Failure of insulation in high voltage insulators in Tanjung Jati B substation Jepara is one of the causes of acid rain due to the condensation of smoke from the Tanjung Jati B power plant chimney. Acid rain arises due to failure Flue Gas Desulphur ( FGD ) devices were installed in the plant to reduce gas emissions as a condition of eco-friendly power plant that is planned by the government through the department of Environment . The real action is taken to dismiss the notion that power plant fuel coal is one of the industries that emit SOx and NOx emissions are high on operational processes . The effects of gas emissions is one of the causes of acid rain on the environment . The amount of acidity of acid rain that occurred in the industrial area will always affect the high voltage power lines that distribute power in operation . Sometimes the equipment functions as an insulator in high voltage substations that distribute power at 500 kV network SUTET JAMALI network on the island of Java in a system of operation is interrupted because of pollutants attached to the insulator . Rain with a pH between 4-5 categorized as acid rain and the test affects the time of the flashover voltage drop of 145.5 kV – 142.5 kV of the working voltage , this causes an insulator as insulation materials can be minimized distance insulator surface so that termites can affect the resistance of an insulator in its function as a tool to restrain the occurrence of flashover voltage from voltage parts.

Abstract

Today, insulation system involves more than one insulation material, whether serial, parallel, or both. In insulation system, the simplest form is composite which consists of two layers of the same material. The benefit of using layered insulation is that the dielectric strength is higher than one layer with the same thickness. There are two methods to test bamboo isolator, i.e., tests of the breakdown voltage of bamboo wall and bamboo fiber. The tests used two methods of composite layers (acrylic and resin) and without composite layer (normal condition). The tests were intended to observe the breakdown voltage on each incidence in each test sample and discover the dielectric strength. The test result showed that the breakdown voltage of bamboo wall was bigger than bamboo fiber with or without composite layer. The highest dielectric strengths of acrylic layer in petung bamboo wall were 2.07 kV/mm and acrylic layer in bamboo fiber was 0.95 kV/mm in layered method. Meanwhile, in ampel bamboo wall it was 1.35 kV/mm and petung bamboo fiber it was 0.43 kV/mm in normal condition (without layer).

Abstract

External lightning protection system consisting of a finial, down-conductor and grounding are important aspects in the installation of lightning rods. The study was conducted by using a finial rod copper that aims to study the protection angle of a lightning rod. High finial of the earth would determine the angle of protection desired. Based on this research, the object of protection is the angle between 85,6° - 89,3°. This suggests that a lightning rod has limitations in protecting an area. The larger the area to be protected, the more number of lightning rod needed.

Abstract

Insulation materials that commonly used in air insulation, which, is operated at high voltage, are the porcelain, glass, and polymer materials. One of the insulating polymer materials that are used is epoxy resin because it has several advantages compared to porcelain and glass. However, this insulation material has a shortage of aging/degradation of the surface (surface-aging) due to environmental pollution. Environmental pollution can cause insulation coated with dirt and chemicals in the long time.Material that was used in this research was epoxy resin polymer isolation using of comparison values (base material diglycidyl ether of bisphenol-A (DGEBA) : hardener material or curing agent metaphenylene diamine (MPDA)) were 1:1, with the increase of silane and coastal sand as filler by the value of 10%, 20%, 30%, 40%, and 50%, sample size was 120 x 50 mm.Research was done in laboratory according to standard IEC 587: 1984. High voltage electrodes were connected to high voltage AC generator 3.5 KV, and NH4CI contaminants flowing on insulator surface of 0.3 ml / min from high voltage electrode. The ground electrode was connected to oscilloscope for measuring the leakage current. In this study, the effect of variation in stoichiometry to the hydrophobic contact angle value, leakage current waveforms, and surface degradation caused by erosion and tracking processes and tracking time were analyzed.From the results of the research, it was obtained that the epoxy resin that was used in this research are categorized as hydrofobik and partially wetted. The increase concentration of silane dan coastal sand as filler caused the increase in contact angle which meant the increase in surface insulation resistance, so that leakage currents flew on the surface insulating material not easily. The increase in concentration of silane dan coastal sand as filler retarded the carbon growth the surface of insulating material. This indicated that the increase in filler concentration slow down the aging or the degradation decreasing on the surface of insulating material. Concentration value of filler that had the optimal performance of the tracking process and erosion was 40%.
