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.

Concordia Transform-Based Current Analysis for Induction Motor Diagnosis
Key Engineering Materials, 2013This paper presents a new approach for bearing defect diagnosis in induction motor by taking advantage of three-phase stator current analysis based on Concordia transform. The current signature caused by bearing defect is firstly analyzed using an analytic model.

Inductive instrument transformers are widely-used to measure currents in the power grid. Harmonics currents increase due to the proliferation of nonlinear equipment in the power grid. At higher frequencies, eddy currents inside the core increase, causing a change of the electrical parameters of the current instrument transformer (CT).

Effect of temperature on the accuracy of inductive current transformers
2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2018The paper deals with the evaluation of the accuracy variation of inductive current transformers vs. ambient temperature. There is a lack of information regarding if and how the accuracy of inductive current transformers changes with respect to temperature variations. To this purpose, in this paper a proper setup is presented and used for evaluating the
