Use of COMTRADE Fault Current Data to Test Inductive Current Transformers [PDF]
2019 II Workshop on Metrology for Industry 4.0 and IoT (MetroInd4.0&IoT), 2019 This paper presents a study on the inductive current transformer behaviour when subjected to distorted actual waveforms. Typical tools adopted to deal with such a condition, as the well-known ratio error, phase error, frequency response, etc. not always provide satisfactory results in all the possible operating condition. In addition, Standards lack in

Amplification of S-1 Spheromak current by an inductive current transformer [PDF]
, 1985 We attempt to predict the consequences of adding an inductive current transformer (OH Transformer) to the present S-1 Spheromak experiment. Axisymmetric modeling with only classical dissipation shows an increase of toroidal current and a shrinking and hollowing of the current channel, conserving toroidal flux.

Estimation of the inductive current transformer derating for operation with distorted currents
Bulletin of the Polish Academy of Sciences Technical Sciences, 2014 Abstract The aim of the paper is to present a new method for estimation of the CT (Current Transformer) rated primary current and / or load of the secondary winding derating levels for transformation of distorted current in relation to the rated values fixed for transformation of sinusoidal current.

Thermal Aspect in Operation of Inductive Current Transformers and Transducers
EnergiesAn increase in the temperature of the magnetic core causes narrowing of its hysteresis loop and reduction in the saturation magnetic flux density. Therefore, at the same operating point on the magnetization characteristic, the nonlinear effect may become
