가공 송전선로에서 발생하는 극저주파 전자계의 국내 현장 여건을 고려한 측정 방법에 관한 연구 = A Study on Measurement Methods of Extremely Low Frequency EMF from Overhead Transmission Lines Considering Domestic Field Conditions

다국어 초록 (Multilingual Abstract)

Exposure to extremely low frequency (ELF) electromagnetic fields (EMFs) from power transmission and distribution facilities has gained increasing attention with rising power demand driven by artificial intelligence (AI). This study proposes a practical EMF measurement method suitable for domestic power facility environments in Korea. Field measurements were conducted on 345 kV and 154 kV overhead transmission lines and 22.9 kV distribution lines based on ICNIRP guidelines and international standards IEC 62110 and IEEE Std 644. Measurements were performed at the maximum sag point at different lateral distances and representative heights. The results show that EMF levels were highest directly beneath the conductors and decreased rapidly with distance, while all measured values remained well below domestic exposure limits.
