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

Gas insulating material commonly used in electrical system is SF6 gas. SF6 gas is used as an insulator material in electrical system in transfer heat. However, SF6 gas is not environmentally friendly, and triggers the increase of global warming so it is necessary to conduct research to get other gas insulators as alternative materials such as gas Carbondioxide (CO2) and Nitrogen (N2). This study discusses the dielectric characteristics of a mixture of Carbondioxide (CO2) gas with Nitrogen (N2) under electrical stress (high voltage negative polarity). The study used spherical electrodes and needles with varying gap distances and we compared the gas breakdown voltage with ratio 25% CO2 : 75% N2, 50% CO2 : 50% N2, and 75% CO2 : 25% N2 respectively. The purpose this research is to find the maximum breakdown voltage for several ratio gases. From the test result obtained breakdown voltage in negative polarity is smaller than positive polarity. We also attempted the gases breakdown voltage 70 trials and it was indicated that the breakdown voltage varied -78,69 kV until -105 kV. The maximum discharge current recorded by an osciloscope was -104 A in 50% CO2 : 50% N2 ratio.Keywords : electrode, mixture insulation gas, polarity efect, dielectric power, negative polarity, breakdown voltage

Abstract

Electrical energy is very important today. The power company distributes the electric energy through the 150 kV overhead lines. The transmission line is a major part of the electrical energy distribution process. Overhead lines are supported by high towers, therefore the overhead lines and towers prone to lightning. The lightning current leads to the increasing voltage on the overhead lines. Surge arrester is a protective device used to protect overhead lines from lightning current. The analysis of the performance of the surge arrester against the lightning impulse requires the investigation in the placement of the surge arrester and the number of surge arresters installed. This study aims todetermine the magnitude of the voltage caused by lightning strikes by varying the location of the surge arrester on the overhead lines. This study was conducted by selecting a lightning strike at apeak voltage of 10 MV on a transmission tower using ATP software. This study indicated that the installation of surge arresters on the overhead lines for each tower leads to droping voltage verywell. The result of study shows that the best result was to install the arresters on each tower phase by decreasing the voltage at 1st tower by 0,4679 MV (92,81%), 2nd tower 0,5674 MV (92,64%), 3rd tower 1,2248 MV (85,79%), 4th tower 10 MV (0%), 5th tower 1,2322 MV (86,09%) and 6th tower 0,6219 MV (92,53%).Keywords : Lightning strikes, surge arrester, peak voltage, placement of surge arrester , voltage drop
