Simplified Magnetic Field Evaluation for Workers with Conductor Loops

Abstract

The Directive 2013/35/EU of the European Parliament is designed to protect workers against the risks of electric, magnetic and electromagnetic fields. Therefore, it is obligatory to evaluate all workplaces with sources causing these fields. This paper shows a simple method for evaluating magnetic fields of electrical energy systems. The method is safe and conservative though with little overestimation, fast and easy to implement even for non- specialists and requires less documentation work. This paper will give the formulas as well as the verification for this method.
