Abstract

This work proposes the survey of magnetic field measurements taken in 154/31.5 kV substations in the city of Antalya for occupational exposure assessment. For measurements, three substations have been taken into account, where four occupants are present for each 8 h of shift, which means 12 occupants are present during the day. Operator desks at three different substations read a lowest magnetic field of 0.3 mu T at minimum loaded season and reached up to 1 mu T at maximum loaded season, which means operators exposed to a magnetic field of >= 0.3 mu T 8 h d(-1). In switch gear regions, maximum magnetic field reading is 23 mu T at minimum loaded season and reached up to 70 mu T. Outdoor magnetic field measurement at circuit breaker region goes up to 62 mu T with respect to operator heights.
