| Summary: | Lightning is a one of the natural events that cannot be predicted when it occurs. When lightning strike any structural buildings or grounded objects can causes miscellaneous damage harm and fatality. In order to protect structure against lightning strikes and reduce the physical damage, properly designed of type and location for Lightning Protection System (LPS) should be carefully considered. The MS_IEC_62305_2007 standard clearly describe about selection and design of Lightning Protection System (LPS) with suggestion methods. So, this thesis that focus on determine the suitable location of air termination system for police station complex at Sri Hartamas, Kuala Lumpur to protect the structure in case of direct lightning strike. This thesis also present a graphical method performed by rolling sphere with specific radius. This is an imaginary sphere which is rolled over structure. In order to get accurate result, all parts of conventional Lightning Protection System (LPS) which is air termination system will be analyzed by using suitable computer software and followed the Malaysia Standard. For down conductor system and earth termination system will be analyzed based on Malaysia Standard. As a result, the structure are located in the radius of this method are protected from lightning strike. |
