Fault current limiter using transformer and modular device of YBCO coated conductor
(2013-04-08)
In this work, we report on the evaluation of a superconducting fault current limiter (SFCL). It is consisted of a modular superconducting device combined with a short-circuited transformer with a primary copper winding ...

Coastal and shelf circulation in the vicinity of Camamu Bay (14 degrees S), Eastern Brazilian Shelf
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The Camamu Bay (CMB) is located on the narrowest shelf along the South American coastline and close to the formation of two major Western Boundary Currents (WBC), the Brazil/North Brazil Current (BC/NBC). These WBC flow ...
A low-cost neurostimulator with accurate pulsed-current control
(Institute of Electrical and Electronics Engineers (IEEE), 2002-05-01)
A constant-current stimulator for high-impedance loads using only low-cost standard high-voltage components Is presented. A voltage-regulator powers an oscillator built across the primary of a step-up transformer whose ...

High-precision current comparator for current transformer calibrations.
(SEMETRO, 2013)
The development and testing of a current comparator (CC) is described. It is intended for ac low frequency applications, such as calibration of instrument current transformers (CT). The CC can be self-calibrated comparing ...

Electrical and Magnetic Characterization of BSCCO and YBCO HTS Tapes for Fault Current Limiter Application
(Institute of Electrical and Electronics Engineers (IEEE), 2011-06-01)
Several high temperature superconductor (HTS) tapes have been developed since the late eighties. Due to the new techniques applied for their production, HTS tapes are becoming feasible and practical for many applications. ...
