The influence of the method of winding construction on metrological properties of current transformers designed for systems of monitoring of power quality

Proper estimation of the power quality in case of high current strength or necessary of separation between tested and measuring circuits requires determine of the level of conductive disturbances through the current transformer. The scope of the article is description of the results of the comparative laboratory research on estimation of accuracy of transfer of distorted currents through current transformers with toroidal core and windings made typical from coil wire and with the aid of a new method from copper wattle. In the paper outcomes of analysis of the influence of the method of winding construction on metrological properties of current transformers during transfer of distorted currents are presented.
