Harmonic Factors for Electromagnetic Field Evaluation in Power Systems according to 2013/35/EU

This article describes the method for magnetic field evaluation according to Directive 2013/35/EU and the Austrian implementation (VEMF). It focuses on a method using a harmonic factor in order to consider harmonics when evaluating multifrequency fields of energy power systems. The differences in the evaluation, and the use of different methods of consideration of the multi-frequency fields is discussed in detail with an example. The main goal is to find a simple method to prove, that the requirements of Directive 2013/35/EU are fulfilled.
