Abstract
The effects of exposure to electromagnetic fields have been the subject of much research. The current industry consensus is that EMFs of the non-ionizing radiation type (low to midfrequency typical of electronic devices and power distribution) have no proven connection with harmful effect in human beings. Even with this extensive research global authorities on health such as the World Health Organisation have taken a stance of “prudent avoidance” and classified EMFs as a Group 2B Carcinogen meaning, “Agent is possibly carcinogenic to humans”. Because of this stance limits to EMF exposure have been recommend by the Institute of Electrical and Electronic Engineers (IEEE) and are referenced in Australian Standards.
This research project seeks to continue this research concentrating on the specialist area of DC traction substations. To complete this research the dissertation includes a literature review to investigate previous studies into electromagnetic fields and has applied that research to examining the levels of electromagnetic fields that substation worker may be exposed to, in the more unique environment of direct current (DC) traction substations.
DC traction substations have different characteristics to traditional substations in their highly dynamic power loading and uncommon plant such as rectifier transformers and diode units. The possible magnetic field strength exposure levels have been assessed using measurements taken onsite at in-service substations and by modelling for worst case loading conditions.
Research into this specialty area is beneficial to the industry as it promotes health and safety of a controversial and largely unrecognised topic in an already hazardous occupation.
Low-cost recommendations have been made with consideration to reducing EMF exposure for substation workers. Whilst these recommendations are unlikely to show any immediate health improvements, they will show a compliance to a safety culture in-line with the current industry accepted philosophy of pretend avoidance.
