Inductive current transformer accuracy of transformation for the PQ measurements

Electric Power Systems Research, 2017
Abstract Inductive current transformer made of magnetic cores with high permeability are used for accurate wideband transformation of distorted current required by the power quality (PQ) measurements. However, such solutions are often characterized by not acceptable additional secondary current distortion in condition of variation of primary current ...

A practical approach to evaluation of accuracy of inductive current transformer for transformation of distorted current higher harmonics

Electric Power Systems Research, 2015
Abstract In this paper the concept is discussed for evaluation of accuracy of inductive current transformer (CT) for transformation of distorted current higher harmonics. In proposed method the composite error (transformer correction factor) is determined for various operating conditions of tested CT in respect of primary currents rms value ...

Wide Frequency Operation of the Inductive Current Transformer with Ni80Fe20 Toroidal Core

Electric Power Components and Systems, 2014
Abstract—During transformation of the power frequency currents, inductive current transformers are characterized by the values of current errors and phase displacement, which determine their accuracy class. However, current transformers catalogues do not specify these metrological parameters of transformation for the sinusoidal signals at frequencies ...
