GROUND LOOP Meaning and
Definition
-
A ground loop is a phenomenon that occurs in electric circuits involving multiple grounding points. It is characterized by the presence of unwanted current flowing through the ground connection. This unintended circulation of current creates an electrical loop or path, hence the term "ground loop."
In simpler terms, a ground loop can be visualized as a situation where there are multiple connections to the ground, leading to a difference in potential between these grounding points. The resulting potential difference causes a flow of current through the ground conductors, which can interfere with the normal operation of electrical devices.
Ground loops commonly occur in audio and video systems where various equipment such as amplifiers, mixers, and monitors are commonly grounded. The differing electrical potential at various grounding points can result in electrical noise, hum, or interference in the audio and video signals. This unwanted noise can lead to distortion, loss of signal quality, or even equipment damage.
To mitigate ground loops, various techniques can be employed, such as the use of ground isolators, balanced audio cables, or the installation of ground lift switches. These measures help to break the loop and ensure that all grounding points are at the same electrical potential, minimizing or eliminating the unwanted current flow. Overall, the purpose of addressing ground loops is to maintain proper signal integrity and ensure reliable operation of electrical systems.

Etymology of GROUND LOOP
The word "ground loop" is a technical term commonly used in the fields of electrical engineering, audio engineering, and aviation. The etymology of the term can be understood by dissecting its components.
1. Ground: In the context of electrical engineering, "ground" refers to a reference point or conductive connection to the Earth, typically used as a return path for electric currents. In this context, "ground" has been used since the mid-19th century to describe the Earth as a conductive surface.
2. Loop: In general, a "loop" refers to a closed path or circuit. In electrical engineering, a loop can describe a complete path of an electric current, often formed by the interconnected conductors or components in a circuit.
Combining these components, "ground loop" is thus formed as a term describing a closed path or circuit involving a connection to the Earth (ground).
