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 ...

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 ...

Wavelet Scattering Transform Based Induction Motor Current Signature Analysisa
2020 International Conference on Electrical Machines (ICEM), 2020In this paper wavelet scattering transform (WST) algorithm is proposed to analyze motor current signatures and extract faults features. The algorithm overcomes the short comings of the classical techniques, which are noise sensitivity and computational complexity in features extraction.
