Most of the electric power systems are using insulating materials such as sulfur hexafluoride (SF<sub>6</sub>). Sulfur hexafluoride gas (SF<sub>6</sub>) has a higher dielectric strength than the air. However, Sulfur hexafluoride (SF<sub>6</sub>) 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 (N<sub>2</sub>) (more friendly environmental) as alternative insulation of sulfur hexafluoride (SF<sub>6</sub>) 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.</p&gt;}, number={2}, journal={International Journal of Electrical, Energy and Power System Engineering}, author={Murdiya, Fri and Firdaus and Pardede, Tumpal and Hamdani, Eddy}, year={2019}, month={Jun.}, pages={7-10} }
