Sažetak
In electrical power transmission system most voltage and current measuring transducers are conventional high-voltage and current measuring transformers with a feromagnetic (iron) core ( convetional measuring transducers). Progress in technology has made possible the development and usage of different kind of measuring transducers without feromagnetic cores or with other ferrite materials that have many significant advances (unconvetional 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 ove conventional measuring transformers with feromagnetic cores: they are affordable, installation costs are reduced, installation is easier and faster, they achieve high accuracy, and have smaller volume and mass.
