Method for large-scale recording of strongly fluctuating low-frequency magnetic fields, in particular during identification of electromagnetic compatibility near conducting installations

摘要

The method involves setting a continuous measuring point in an object to be measured. A measurement of magnetizing force is carried out over 24 hours. A set of comparison measurements is realized parallel and simultaneous to a continuous measurement at different measuring points of the object. Maximum values of the continuous measurement are set to isochronous values of the comparison measurement and absolute maximum values of the continuous measurement. Entire related magnetic field load of the object is represented in period of the continuous measurement.
