Abstract

Abstract—Epoxy resins are the solid insulation that are widely used to increase the high voltage insulators. In order to increase the dielectric and mechanical strength of epoxy resins can be mixed by using materials such as alumina, palm kernel shells and cnt (carbon nano tubes). From this research of epoxy resin mixed with palm kernel shells with a diameter of 1 mm looks the electrical breakdown characteristics uniquely. With the addition of palm kernel shells can raise breakdown voltage of epoxy resin, compared to pure epoxy resin. The increasing of breakdown voltage is affected by the dielectric strength of palm kernel shells were higher rather than epoxy resin. Discharge currents were recorded from the measurements at laboratory on samples showed different results. At the time of the solidinsulator is approached the electrical breakdown, discharge currents can have a lot of pulses. From these results, a mixture of epoxy resin and palm kernel shells can be used as a new insulator. The properties ofdielectric strength and discharge currents that occur at the time of measurement in the lab shows the different and unique.Keywords ; epoxy resin, palm kernel shell, breakdown voltage, discharge current

Abstract

One potential that can be utilized as a source of small-scale electrical energy is irrigation canals. The obstacle experienced to utilize irrigation canals is because irrigation canals have low flow speeds and height differences in irrigation canals. In this study, a power plant was made in an irrigation stream with a flow speed of 0.3 m/s and a height difference of only 0.3 meters. This research began with a survey of the design and manufacture of waterwheels, transmission systems, and generators. After all components are installed, the generator output voltage measurement is carried out using lamp loads of 3,6,9,12,25 and 49 Watts. From the measurements, it can be seen that as the load increases, the rotation of the wheel, voltage, and frequency will also decrease. This is due to the lack of water power so that the water is no longer able to turn the waterwheel.

Abstract

The distribution of electrical power from the power plant to the center of the load on the transmission line can occur the electrical fault. This fault that often occurs is a transient overvoltage caused by a direct lightning stroke. Lightning stroke can cause the lightning impulses which are the dominant factor in generating the transient over voltages on 150 kV overhead lines compare to the high voltage cable lines. This investigation studied the effect of lightning stroke on the 150 kV mixed transmission lines using the ATP-EMTP (Alternative Transient Program – Electromagnetic Transient Program) software . The data analysis is carried out by simulating all line parameters and evaluating the transient overvoltage value on the transmission lines. It is shown that the highest transient overvoltage occurs when the lightning strikes on the ground static wires compared to when the lightning strikes on the phase wires. It is also shown that the use of the 150 kV mixed-lines can decrease the overvoltage caused by the direct lightning stroke. The installation of arresters on the transmission towers provides a significant reduction in over voltage caused by lightning stroke.Keywords : arrester, ATP-EMTP, lightning, mixed transmission lines, transient over voltage.

Abstract

Ozone is used in various area including medicine, drinking water treatment and waste treatment. Ozone can be produced using dielectric barrier discharge which is supplied by high voltage. High voltage occurs in the dielectric barrier discharge such as air gap that it is as a result of the failure of air in maintaining its insulator properties. Power supply used in this study is a parallel resonant push-pull inverter using a fly back transformer. In order to produce good plasma in producing ozone, a magnetic filed is added to dielectric barrier discharge. In this study, a magnet was placed on each anode and cathode electrode with the condition of attraction (model I) and repulsion (model II). The addition of two magnets to each electrode was also carried out under the conditions of attraction (model III) and repulsion (model IV). It is shown that the plasma intensity in the model I and III was higher than model II and IV. The discharge current in the model I and III was higher than model II and IV. The highest ozone concentration was model III and the lowest ozone concentration was in model IV. Model I had a higher ozone concentration than model II.

Abstract

The type of insulation gases that are usually used in the power circuit breaker (circuit breaker) is the sulfur hexafluoride (SF6) gas, nitrogen (N2) and carbon dioxide (CO2). Most of the electric power systems are using insulating materials such as sulfur hexafluoride (SF6). Sulfur hexafluoride gas (SF6) has a higher dielectric strength than the air. However, Sulfur hexafluoride (SF6) gas is not friendly environmentally and very impact on global warming. The purpose of this study was to test the breakdown voltage of nitrogen gas (N2) (more friendly environmental) as alternative insulation of sulfur hexafluoride (SF6) gas. This study was used sphere and needle electrodes with a distance of 0.5-2 cm and a pressure of 1-4 bar; it was tested for 20 times. From the test results, it obtained that the breakdown voltage of sphere electrodes is more significant than the needle electrodes. Sphere and needle electrodes with a distance of 2 cm and a pressure of 4 bar have a most excellent value of breakdown voltage at the voltage of 140 kV and 79 kV, respectively.

Abstract

The utilization of ozone is commonly applied in various fields, for instance, it is used as a disinfectant for water treatment, disinfecting, sterilizing medical devices and preserving foodstuffs. Ozone is a nearly colorless gas with a characteristic odor that can be detected by humans up to 0.01 ppm. It can be produced by the dielectric barrier discharge method,which is generally used as a method of generating ozone supplied by high voltage or also called high voltage plasma generators. High voltage plasma occurs in the dielectric barrier discharge air gap, as a result of the air failed in maintaining its insulator properties. The power supply used in this study is a parallel resonant pushpull inverter using a flyback transformer. Furthermore, this study did not use an additional magnetic loudspeaker and used ceramic dielectrics instead. 5 types of ceramics and 2 different types of granite and combined the range of air gap were used during examination and research. The research indicates that the best plasma was found in ceramics 3, 5, granite 1 and 2 with an air gap of 2mm. The current discharge in ceramic 1 with an air gap of 2 mm was higher than the others. The highest voltage discharge was on granite 2 with an air gap of 2 mm. Ceramics 3, 5, granite 1 and 2 with an air gap of 2mm had better ozone concentrations than ceramics 1, 2 and 4.
