Define Electrical Ground Loop

A ground loop is formed when two or more points in an electrical system that are nominally at ground potential are connected by a conducting path such that either or both points are not at the same potential while this is a good general purpose definition it is.

Define electrical ground loop.

According to the ansi ieee standard dictionary of electrical and electronics terms it s a potentially detrimental loop formed when two or more points in an. But an electrical circuit may be a combination of one or more networks which gives closed path to the electric current. A common example is two pieces of electrical equipment a and b each connected to a utility outlet by a 3 conductor cable and plug containing a protective ground conductor in. An electric circuit based on three concepts namely node branch and loop as per definition an electric network is a combination of interconnected circuit elements a network may or may not provide closed path to the electric current to flow.

An excellent broad definition is that a ground is simply a return path for current. A ground loop is caused by the interconnection of electrical equipment that results in there being multiple paths to ground so a closed conductive loop is formed. Electrical circuits may be connected to ground earth for several reasons. Exposed metal parts of electrical equipment are connected to ground so that failures of internal.

A formal definition of a ground loop that is very general is provided in ieee std. In an electrical system a ground loop usually refers to a current almost always unwanted in a conductor connecting two points that are supposed to be at the same potential often ground but are actually at different potentials ground loops created by improperly designed or improperly installed equipment are a major cause of noise and interference in audio and video systems. Unwanted ground loops can cause inaccurate sensor readings by negatively affecting instrumentation signals have you ever had problems with process controls and electrical instrumentation. 100 1991 ieee dictionary as follows.

The source may be ground loops. Generally ground loop connection exists when an electrical system is connected through more than one way to the electrical ground. The physics of electrical flow are more complicated than most simple explanations can convey but essentially electricity seeks to return its electrons to ground that is to discharge its negative energy and return to equilibrium. Cedia est016 understanding finding eliminating ground loops page 5 1 grounding ac power and safety broadly the purpose of grounding is to electrically interconnect conductive objects such as equipment in order to minimize voltage differences between them.
