This paper aims to explain the pointer image theory as a solution used to predict the commonmode (CM) current at power lines, which is strongly related to radiated electromagnetic emissions.Techniques to measure the CM current at power lines in huge installations such as wind turbines(WT) are needed and novel methods are emerging. The WT tower may become an unintentionalantenna due to the CM current flowing at its body through stray capacitances. The easiest way tomeasure the total CM current flow on a three-phase system is by measuring it using a device suchas a current clamp or a Rogowski coil. This clamp must cover the whole 3-phase-cable bundle,however, the problem is that such a huge clamp or coil does not exist on the market, besidescustomized parts. The proposed method in this paper is to implement the pointer image theory topredict the CM current from a WT power plant. Laboratory measurements and SPICE simulationsare used to show that the proposed method works well for CM current prediction.
