Ground loop
From Wikipedia, the free encyclopedia
The term ground loop has more than one meaning:
- Ground loop (electricity), in electrical engineering and electronics, refers to an unwanted electrical current that flows in a conductor connecting two points that are supposed to be at the same potential, for example ground potential, but are actually at different potentials.
- Ground loop (aviation), in aviation, refers to the rapid circular rotation of an aircraft in the horizontal plane while on the ground. Ground loops are common with taildraggers, as the center of gravity is behind the main undercarriage.
- A ground loop is sometimes used to mean a Ground-coupled heat exchanger.
