The superconducting fault current limiters have been expected as a possible type of power apparatus to reduce the fault current in the power system. The transformer type superconducting fault current limiter, which consists of a series transformer and a superconducting current limiting device, is one type of the superconducting fault current limiter ...

Review of Scientific Instruments, 1979
Transformer–rectifier flux pumps using thermally switched Nb3Sn cryotrons are being investigated as a loss make-up device for the proposed isochorically operated (sealed) superconducting magnets for the Canadian Maglev vehicle. High currents (1000 A) were obtained in an experimental flux pump using inductive current transfer and operating at 2 Hz.

Line current analysis for bearing fault detection in induction motors using Hilbert transform phase
International Aegean Conference on Electrical Machines and Power Electronics and Electromotion, Joint Conference, 2011The present paper focuses by means of an experimental study, on the effect of a bearing fault on the stator current signatures in induction motors. The variation in the amplitude of the characteristic components is not so significant. For that and in order to depict the presence of the fault harmonic signatures, the authors used the phase analysis of ...

Abnormal current is the result of a power system fault for which all components must be well designed. And also it is highly difficult to estimate the number of such occurrences in the network.

Fast power ``crowbar'' system using a current transformer with extremely low leakage inductance
Review of Scientific Instruments, 1974A power crowbar system for fast θ-pinch experiments is operated successfully. A current transformer with extremely low leakage inductance is used to reduce the effective impedance of series capacitor system. The leakage inductance of the transformer is reduced to 2 nH by employing a special arrangement of windings.

This paper presents a study focused on the equivalent parameters of an inductive current transformer for medium voltage purposes. In particular, its equivalent parameters behaviour has been assessed by varying both the temperature and the working conditions (current and voltage). Preliminary results provide interesting “calibration” curves which may be

THD uncertainty estimation for inductive current transformers using the accuracy class information
2020The Total Harmonic Distortion (THD) measurement is among the key elements to assess the power quality of a network. However, the Standards does not provide sufficient information to evaluate the uncertainty related to THD, neither voltage nor current one.
