... on top of a NMOS pull-down network (PDN); where the pull-up and pull-down outputs are DeMorgan duals of each other [2]. These gates behave much like an inverter, with the PUN charging capacitances and the PDN network discharging them. As such, much of what has been said above holds true here and the ...

Effect of Neutral Grounding Methods on the Earth Fault

... A fault on a power system is an abnormal condition that involves failure risks of power system equipment. Generally, two types of failures can occur. The first is an insulation failure that results in a short circuit fault. The second is a failure that results in an interruption of current flow. Sho ...

Ground loop (electricity)

In an electrical system, a ground loop is an equipment and wiring configuration which results in excessive unwanted current in a conductor connecting two points that are supposed to be at the same electric potential, often ground, but are actually at different potentials.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections merely create a not necessarily very good instance of Electrical_bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems thought to be caused by ground loops.
