High speed, high current interrupting devices are interrupting devices that have extremely short opening times and are current limiting; that is, they limit the amount of bolted fault current that can ...

For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...

What's the difference between a short-circuit current rating (SCCR) and an interrupting rating (IR)? If you're not sure, clearing up the confusion could be as simple as brushing up on your definitions ...

Protecting an electronic circuit from damage due to excessive current or heat is the primary function of many circuit protection technologies. In the past, this protection took the form of a fuse or ...

The rapid expansion of high voltage direct current (HVDC) grids, driven by the massive integration of renewable energy sources, has underscored the critical role of DC circuit breakers (DCCBs) and ...

Restrikes or re-ignitions occur when the dielectric strength of the open gap, during contact parting, is not great enough to withstand the recovery voltage across the open gap. With a capacitive load, ...
