When designing ground-fault protection (GFP) for a power distribution system, you should always consider the nature of the power source. If the power source is from a separately derived system, you ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

The motion of charged particles causes electrical effects, small shocks, lightning and sparks. Electrical fields cause forces to act on charged particles. How to affect electric current - OCR 21st ...

There is a rising chorus of concern across the energy industry that the electric grid is facing a surge in power use that our infrastructure won’t be able to handle. The historical stewards of our ...
