Why Should We Test the Wideband Transformation Accuracy of Inductive Current Transformers?
Energies, 2022 Inductive current transformers are characterized by different transformation accuracies for higher harmonics of distorted primary currents. Therefore, it is highly required to perform the tests of their metrological properties to choose the best unit ...

Polypoint transformations algorithm accuracy increase [PDF]
APPLIED GEOMETRY AND ENGINEERING GRAPHICS, 2020 Deformation simulation methods allow to show the deformation processes of the objects without certain kind of functional description by defining dynamic deformation parameters. Deformation is applied to the space where object exists, and allows to retrieve the accurate changes of an object. The one of such models class is policoordinate methods, namely,
