Abstract

Insulation of Sulfur hexafluoride (SF6) gas, nitrogen (N2) gas and Carbon Dioxide (CO2) gas usually used in circuit breaker. Sulfur hexafluoride (SF6) gas is widely used in high-voltage system. Sulfur hexafluoride (SF6) gas has a higher dielectric strength than the dielectric strength of air. However, Sulfur hexafluoride (SF6) gas is not environmentally friendly and very impact on global warming.The purpose of this study was to test the breakdown voltage of nitrogen (N2) gas is more environmentally friendly as an alternative to insulation of sulfur hexafluoride (SF6) gas. This study use electrodes balls and needles with a distance of 0.5-2 cm and use pressure of 1-4 bar being tested as much as 20 times the experiment. From the test results obtained that the breakdown voltage electrode bigger balls than the electrode needles. Electrode balls with a distance of 2 cm and a pressure of 4 bar has a value of breakdown voltage greater than 140 kV, while the electrode needles with a distance of 2 cm and a pressure of 4 bar has a breakdown voltage of 79 kV.Keywords : Electrodes, Nitrogen (N2) Gas, Insulation of Gas, Dielectric Strength, Breakdown

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.
