But burden resistor selection is not a simple task because involves a lot of considerations that affect the output voltage and its signal-to-noise ratio and the bandwidth of the measure. In this paper, considering the basic equations of the transformer and applying the Laplace Transformation is obtained a simple model of the current transformer interesting to select burden resistor and even to design the current transformer in case of high frequency applications Postprint (published version) Àrees temàtiques de la UPC::Enginyeria electrònica Industrial electronics Electronic control Current measurement current transformer burden resistor Control electrònic Electrònica industrial Burden resistor selection in current transformers for low power applications
