Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

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 ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

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 ...

Munich – Schaltbau has introduced a special innovation for AC-driven electric locomotives and multiple units: an AC vacuum circuit breaker that can almost do without any secondary supply energy for ...

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 ...
