ground current

Unwanted current in a ground line. It may be caused by imbalanced electrical sources; for example, the ground line in a communications channel between two computers deriving power separately. See ground loop, inter-system ground noise and ground.

If the adjacent plane is close to the split plane and there is a lot of overlap area on each side of the split, the ground impedance will be quite low, and most of the ground current will follow that path.
Multiple ground paths set up ground currents traveling in different directions.
The NCP5915x, NCP5930x, and NCP5830x series are high precision, very low dropout, low ground current voltage regulators that are capable of providing large load currents with a typical dropout voltage lower than 300mV.
As mentioned in Section 2, by achieving the orthogonal ground current path with respect to that from Antenna 2, the mutual coupling between the LTE MIMO antenna elements can be reduced.
Traditionally, ultra-low IQ CMOS LDOs used constant biasing scheme, with the ground current consumption kept relatively constant across the available range of output currents.
While rim arrays were used to prevent lightning strikes to floating roof storage tanks, multiple Retractable Grounding Assemblies [TM] were deployed to prevent arcing at the gap between the seal of the floating roof and the tank wall, caused by lightning storm and ground current activity.
* The TPS799275 low-dropout (LDO), low-power linear regulator that offers AC performance with very low ground current, according to the company.
Locating and correcting the ground current sources (code violations or shorts) should solve excessive AC power magnetic fields emanating from the building steel, HVAC ducts, metal pipes or conduits.
The preferred ICT metrology, shown in Figure 1, uses a voltage source as a stimulus generator (Vs) and a transimpedance amplifier or a virtual ground current meter to detect the current ([I.sub.x]) that flows through the unknown device (Zx).
If a wave is launched from the end of the ACPW, it creates a ground current I.
* Lightning strikes produce ground currents in the area surrounding a lightning strike.
