Abstract

Overview

This case study investigates the occupational exposure to extremely low-frequency electric fields experienced by workers at 220 kV substations, with a focus on identifying whether the exposure levels exceed the regulatory action levels as set by Directive 2013/35/EU.

Findings

  • Previous research highlighted elevated exposure risks at 400 and 110 kV substations.
  • The present study extends this examination to 220 kV substations.
  • The action level of 20 kV/m was exceeded at both substations tested, indicating significant occupational exposure.

Conclusion

This study substantiates the health risks associated with occupational exposure to electric fields at substations, significantly exceeding recommended safety levels contributing to potential long-term health effects.
