Circulating ground current
WebGround Loop zGrounds from two different derived system are connected zOpen ground loops. Grounds are not bonded properly and cause damage. zGround loops cause circulating current between systems and cause transformer coupling (CT’s) zSignal reference can be compromised causing data errors. Current may be produced in a circular ground connection (ground loop) by electromagnetic induction . Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. Wiring practices that protect against ground loops include ensuring that all vulnerable signal … See more In an electrical system, a ground loop or earth loop occurs when two points of a circuit are intended to have the same ground reference potential but instead have a different potential between them. This is typically … See more The circuit diagram illustrates a simple ground loop.

Of those … See more A ground loop is caused by the interconnection of electrical devices that results in multiple paths to ground, thereby forming closed … See more A common type of ground loop is due to faulty interconnections between electronic components, such as laboratory or recording studio equipment, or home component audio, video, and computer systems. This creates inadvertent closed loops in the ground … See more In analog video, mains hum can be seen as hum bars (bands of slightly different brightness) scrolling vertically up the screen. These are frequently seen with video projectors where the display device has its case grounded via a 3-prong plug, and the other … See more
