Abstract

This paper applies to the electrical engineering world by making earthing system portable in providing low and acceptable resistance path. The system is develop in a small scale portable earthing system against the massiveness of Earth and becomes leverage if soil at the place is not suitable for plant grounding system. Hence, this paper presents findings on the research of new grounding medium material that will be housed in a small scale enclosure which behaves like native earth related earthing system by using kaolin and bauxite. The data obtained from lightning flashover testing, morphological and chemical composition of material analysis indicated that bauxite is more useful for portable grounding system application much better than kaolin in term of zero reference point function. The portable earthing system can be apply to air aviation systems , railway systems and military sectors particularly for electronic equipment zero referencing.

Abstract

Human population and power consumption keeps on growing with each year. In order to satisfy electricity demand, more electrical energy has to be supplied, resulting in higher magnetic field level radiation. In rapid urbanization country, lack of space will force civilization to be built near overhead transmission line that sparks public concern on adverse health effects due to the magnetic field radiation. A new UTHM hostel residential area was built near OTLs that shared the same concern. Thus a proper planning to conduct magnetic field level measurement was done to examine the maximum magnetic field level radiated that covered the hostel residential area. The results were far from reaching the maximum permissible magnetic field level proposed by ICNIRP. Though, the steps taken and the methods used might be suitable guidelines for others that encounter similar situations.
