Switching on Short Circuit Current in an Electric Circuit

Proceedings of the 41st International Universities Power Engineering Conference, 2006
Closing or opening the contacts of a electrical switches is normally done in a totally random fashion and consequently, transient current and voltage disturbances may appear in the electrical system. A way for controlling this transient behavior is possible by operating the switch in synchronism with either the current or the voltage oscillations ...

Short-circuit in the magnetosphere-ionosphere electric circuit

Geomagnetism and Aeronomy, 2013
We describe, for the first time, the following peculiarities of a substorm in the polar ionosphere and magnetotail including its distant lobe: (1) coherent variations in mesoscale vortices and in field-aligned currents of the magnetospheric-ionospheric (M-I) system; (2) instability of short—circuiting of currents in ionospheric part of the M-I system; (

The T-Group: Short cut or short circuit?

Business Horizons, 1973
Abstract T-group or sensitivity training has become popular in recent years. A T -group includes eight to twelve people and a qualified leader; its purpose can be to provide therapy or to promote personal improvement or organization development. Beset by organizational problems, some top executives have instituted T-groups, thinking they may be a ...

Modeling of IGBT Short-Circuit Behavior

physica status solidi (a), 2002
Power electronic applications require components with highly efficient switching capabilities. The switching imposes electrical and thermal stresses on the components especially when defects occur. So it is necessary to know the extreme working limits for different loads.

Short Circuit Techniques

1972
Rectifier systems may be subjected to short circuits at any time, and consideration of the consequences is necessary during the design stages. The term rectifier systems includes all types, but most directly those containing silicon diodes or thyristors.

Short circuit calculation

2013
Calculation of short circuit values is essential in power system analysis. The results are used in a number of applications like sizing of breakers and other elements of power systems, designing grounding grids, setting protective equipment, evaluating Total Harmonic Distortion (THD) of harmonic currents, and performing arc flash analysis.

Experience in Short Circuit Testing of LV Short Circuit Testing Transformer

2011 North American Power Symposium, 2011
For an On-line Short Circuit Facility, the main component of the facility is the Short Circuit Testing Transformer. There are no regular manufacturers of such transformers. Design of such transformers needs to be done taking into account many factors. The role of the manufacturer in getting the transformer designed for a particular application is very ...

Magnetic circuit for speaker with short-circuiting ring

The Journal of the Acoustical Society of America, 2006
A magnetic circuit for a speaker comprises: a bottom yoke including a center pole; a ring magnet; a top plate; and a short-circuiting ring shaped like a hollow cylinder. The short-circuiting ring is disposed close and parallel to a voice coil and attached to the inner portion of the bottom of the top plate.

Short-circuit analysis

2016
In this chapter, a method for the short-circuit analysis of radial and meshed distribution systems has been explained in details. The results obtained from the discussed method have also been compared with PSCAD simulation results to establish their accuracy. The values of the calculated short-circuit currents can be used for the selection of equipment
