Abstract
The paper presents how the measured extremely low frequency (ELF) electric fields (EFs) fluctuate in the same measurement place when the humidity varies. EF measurements were performed at three places near 400 kV power lines. In Place A (nine measurements), the EFs varied from 6.8 to 12.5 kV/m when relative humidity was from 70.5% to 86%. In Place B (five measurements), the EFs were 5.1–8.2 kV/m when relative humidity ranged from 67% to 76%, and in Place C (two measurements), the EFs were 0.90–0.92 kV/m when humidity was 68–76%. The measured EFs varied significantly.
