The object of the study was to investigate extremely low frequency (ELF) electric field exposure measurement methods under power lines. The authors compared two different methods under power lines: in Method A, the sensor was placed on a tripod; and Method B required the measurer to hold the meter horizontally so that the distance from him/her was at least 1.5 m. The study includes 20 measurements in three places under 400 kV power lines. The authors used two commercial three-axis meters, EFA-3 and EFA-300. In statistical analyses, they did not find significant differences between Methods A and B. However, in the future, it is important to take into account that measurement methods can, in some cases, influence ELF electric field measurement results, and it is important to report the methods used so that it is possible to repeat the measurements.
本研究的目的是调查电力线下极低频（ELF）电场暴露的测量方法。作者比较了电力线下两种不同的方法：在方法A中，传感器放置在三脚架上；方法B要求测量者水平握住测量仪，使其与测量者的距离至少为1.5米。该研究在400 kV电力线下的三个地点进行了20次测量。作者使用了两台商用三轴测量仪，EFA - 3和EFA - 300。在统计分析中，他们没有发现方法A和方法B之间存在显著差异。然而，在未来，重要的是要考虑到测量方法在某些情况下可能会影响ELF电场测量结果，并且报告所使用的方法以便能够重复测量是很重要的。
