A power system functions normally until after the occurrence of a fault in the system. The good news is fault events can be minimized or avoided through diligent electrical design, accurate record ...

This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...

In order to continuously improve the transparency of power distribution grids, it is important to have precise knowledge about the relevant conditions in the local grid. This is achieved by utilizing ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

SiC MOSFETs are usually susceptible to damage as a result of short-circuiting events because of the fast switching speeds and low on-state resistance. 3 A team of researchers affiliated with the ...

On April 14, in Jinchang city, Gansu province, as soon as the command was given, an artificially simulated single-phase instantaneous grounding short-circuit arc was instantly triggered at the ...

What is a desaturation detection circuit? A desaturation fault detection circuit provides protection for power semiconductor switches (IGBT or MOSFETs) against short-circuit current events which may ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...
