Abstract

The survey of magnetic field measurements from the 154/31.5 kV substation in the city of Antalya have been proposed for an occupational exposure assessment. The magnetic field measurements are carried out from a substation equipment; including all transformers, circuit breakers, feeders and buses, under the in-coming and out-going power lines and operator tables surrounding the substation. The magnetic field is measured as 0.46 µT at the minimum loaded season and 1.34 µT at maximum loaded season over the operator desk. Workers are exposed to 0.3 µT and even more magnetic field for eight hours period per day. In switchgear regions, the maximum magnetic field measurement is 20 µT at the minimum loaded season and may reach up to 65 µT. Outdoor magnetic field values at the circuit breaker region may approach to 45 µT depending on operator heights.
