Abstract
The main contribution of this project is the development of a homogeneous model of a man to presents the specific absorption rate (SAR) due to high power transmission line. As a low frequency application under high power transmission line of 50 Hz in electrical engineering, to studies the influence of human’s posture on specific absorption rate. This project designs two types of human body which one design uses most cylinder block and another design use brick block where both blocks have a different value of mesh cells. For each design has four types of posture are standing, sitting, arms up and arms out by using Computer Simulation Technology (CST) Studio Software. This analysis does toward for four types of the human position postures because each posture has different value of specific absorption rate (SAR) based on the size of the mesh cells of the design. Based on two designs of the human body, the lowest of the mesh cells value will reduce time to simulate SAR. For each posture has different value of SAR for each part of the human body because the whole human body has different types of tissues. Therefore, the CST studio software uses extremely to simulate the SAR value toward human position posture due to high power transmission line.
Highlights
This project discusses about level of specific absorption rate (SAR) due to high power transmission line in Malaysia where uses 50 Hz of frequency to simulate the SAR value toward human body
SAR means a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field
International Commission on Non-Ionizing Radiation Protection (ICNIRP) and IEEE has impose the maximum of 2 watt per kilogram (W/Kg) absorbed per 10 g of tissue [10, 11]
Summary
This project discusses about level of specific absorption rate (SAR) due to high power transmission line in Malaysia where uses 50 Hz of frequency to simulate the SAR value toward human body. This analysis was done toward on four types of the human position postures which is standing, sitting, arms up and arms out posture. The ICNIRP have defined SAR with unit watt per kilogram (W/Kg) and reference level of field strength from exposure to EMF to protect workers and public avoid health effects [3,4,5]. SAR means a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. ICNIRP and IEEE has impose the maximum of 2 W/Kg absorbed per 10 g of tissue [10, 11]
