Electromagnetic Fields Measurements - Methods and Accuracy Estimation

摘要

The paper presents theoretical analyses and measurements results of factors affecting the precision of survey EMF measurements. Presented problems are connected mainly with errors of a method and imperfection of the measuring device. In particular: using probes with non-zero geometrical dimensions, difference between conditions of calibration and measurement (eg. modulated and pulse fields), uncertainty of calibration, nonlinear dynamic characteristic and frequency response and "human factor".
