Design and Calibration of Inductive Current Transformer
Advanced Materials Research, 2013In this paper, the design principle of inductive current transformer is introduced at first. Then an inductive current transformer is produced by applying the structure of two-stage inductive voltage divider. And finally, the error of the sample machine is given through examine test, and the suggestion for improving the machine is given based on the ...

Inductive current transformer accuracy of transformation for the PQ measurements
Electric Power Systems Research, 2017Abstract 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 ...

2015 Modern Electric Power Systems (MEPS), 2015
In the paper the influence of conductive disturbances on transformation of fault current by inductive protective current transformers is described. Analysis of the results from laboratory studies show, that for such condition primary current up to which the current transformer will comply with the requirements for composite/ratio error is decreased ...

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, 2014Abstract—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 ...
