Investigate and Analyze the Electromagnetic Field Levels Inside Electric Power Substation

Abstract

Electric power transformers are a very important part of modern electric power and transmission line network systems and they consider as a high level source of electromagnetic fields which can affect the health of workers in station. In this research, electric and magnetic fields caused due to the operation of power distribution substation of 132/33 kV are investigated in order to avoid the overexposure of these fields to workers. Research has been conducted on both the mathematical calculations and practical measurements. The intensities of electric and magnetic fields have been measured at substation by EMF tester device. Safe zones from some equipment have been determined. Comparison the obtained results with the standard safety guideline limits shows that they are within the acceptable limits.
