摘要: Abstract In this paper, extremely low frequency (ELF) magnetic fields (MFs) were measured during the temperature-rise test of various electrotechnical equipment. The number workers subjected to from is small; however, exposure can be significant as testing currents in order hundreds amperes. resultant field exceed ICNIRP limits for occupational exposure. was recorded and statistical measures extracted three apparatus. It found that Time-Weighted Average per unit current reach 0.0598 μT/A. Additionally, mitigate exposure, a rule thumb regarding safety distances has been proposed. shown use reduce
