Lightning Air Terminal Collection Volume Assessment: A New Technique and Device
Abstract: For buildings,
structures and facilities a Lightning Protection System (LPS) is very
important. There are some components that affect the effectiveness of LPS. One
of the components is the lightningair terminal. With reference to the
facilities requiring lightning protection the position, the apparent height, and
the angle of protection of lightning air terminals determines the collection
volume (CV) of the protected area. The CV of direct strike lightning air
terminals can change because of the facility is affected by naturaldisasters
such as seismic tremor and flood. If such natural disasters do happen, there
are possibilities thatthe facilities will not be fully protected from direct
lightning strikes. The building and structure could be misalignment after the
seismic tremor and flood related to earth movement. So for the safety of
equipment and personnel, lightning protection system efficacy assurance is
necessary. Therefore, there should be a technique and device to monitor the
variation of collection volume afforded by every lightning air terminal on buildings
and structures after the occurrence of a natural disaster. This paper presents
a new technique as well as a new device to monitor the collection volume
variation. A part of the device was obtained from a recycled moveable
television antenna. This approach is not only practical, portable and cost
effective but also incorporating the idea of environmental protection and
recycling of used plastic materials.
