Powerplants. Central stations Rapid growth of high voltage technology gives the opportunity to engineer to do a study on the environmental protection. Production high voltage power is due to natural conditions that could harm and damage the ecosystem of the human condition. In electrical power system, HV power equipment are mainly subjected with spark over voltage. These over voltage which may causes by the lighting strokes, switching action, Normally, the standard sphere gaps are widely used for protective device in such electrical power equipment. The sphere gaps are commonly used for measurements of peak values of high voltages and have been adopted any designing in HV equipment. This project is study about the effect of gap length of sphere-sphere electrodes on air breakdown level under lightning impulse. This project is started by experimental setup and producing standard impulse voltage. The lightning impulse produce should be meets the specifications required by BS EN 60060-1:2010. The standard characteristic of impulse voltage 1 2 T /T where 1 T is the front time while 2 T is time to half value also discussed. The procedure of the lab which implement also referred from Terco High Voltage Experiments. The method that will use in this project is Up and Down Method to obtain U50. From this method, we can examine the average value of breakdown of an impulse lightning voltage is applied to the electrodes. The project also discusses about the electric field density while the impulse voltage is loaded into the sphere to sphere electrode and separated it at desire air gap by using the FEMM software. The characteristic either uniform or non-uniform results also present in this project. Level of insulations at desire gaps between the sphere’s gap also obtain after complete this project. 2014 Thesis NonPeerReviewed application/pdf http://eprints.uthm.edu.my/6625/1/AHMAD_AZLAN_HAMZAH.pdf Hamzah, Ahmad Azlan (2014) Effect of gap lenghts of sphere-sphere electrodes on air breakdown level under lightning impulse.
