The smart grid is the next evolution of the electricity grid with the convergence of electric power, telecommunications infrastructure and information technology. The ultimate goal is to allow ...

Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

Once an engineer has designed the audio circuit of an amplifier, it would be nice to think that most of their task is complete. However, from a system perspective, that is far from true. At the very ...

Understanding the overcurrent trilogy will help you protect your circuits. Circuit overcurrent protection encompasses overload, short-circuit, and ground-fault protection. NEC Art. 100 defines ...

For the PDF version of this article, click here. Protecting power transistors against overcurrent failure has always been a challenging issue in power circuit design. In order to protect against even ...

The circuit protection market is filled with such a wide variety of fuses today that the previously accepted method of specifying fuses is just not enough. Instead, the proper application of fuses in ...

When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 VDC supply and keeping load circuits that aren’t impacted by the failure ...

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp. I put a hose ...
