| Popis: | 101 Adjustment of the installation position of a grounding wire of lightning rod is a solution to reduce the destruction of appliances and electrical equipments as the building was struck by lightning. This thesis is a study of the location of the lightning rod grounding wire set. The analysis suggests that the ground wire had better be outside the building stirrups without concrete. This experiment uses series of high voltage discharge circuit to simulate lightning stroke to reinforced structures, and uses the high frequency current transformer (HFCT) to measure the induction of grounding wire to stirrups of reinforced structures. It investigates the induction of grounding wire placed within or outside the stirrups. The grounding wire outside should be located at long and short side of stirrup. The measurement and records are used to analyze the data and characteristics of the induced current. The result shows when grounding wire is set outside the building beams and columns stirrups without concrete, the surge current and power can be effectively released, and thus make the electrical facilities within the building be protected. This experiment also shows that a further improvement is required for current construction methods. |
