Abstract

In electric power transmission systems most voltage and current measuring transducers are conventional high-voltage and current measuring transformers with a ferromagnetic (iron) core (conventional measuring transducers). Progress in technology has made possible the development and usage of different kind of measuring transducers without ferromagnetic cores or with other ferrite materials that have many significant advances (unconventional measuring transducers). This essay shows the theory of unconventional methods of measuring voltage and current signals and the most important characteristics of unconventional measuring transducers. Unconventional measuring transducers have numerous advantages over conventional measuring transformers with ferromagnetic cores: they are affordable, installation costs are reduced, installation is easier and faster, they achieve high accuracy, and have smaller volume and mass.
