Earth, general symbol Ground USgrounding USgeneral symbol The earth electrode and its connections Regardless of its resistance, an earth electrode is not functional Even for safety reasons, fortunately for medical implants, automotive electronics, aircrafts, helicopters, satellites.

Protective earthing Protective grounding USprotective earthing conductor, protective earthing terminal, protective grounding conductor USprotective grounding terminal US The earthing conductor role is to protect people for safetyso why 2 different symbols? Noiseless chadoy Status level: Obsolete – for reference only To be clear: Functional earthing, functional grounding US Alternative names: Functional earthing conductor, Functional earthing terminal To be clear: There is no functional earthing in industry!

Only used for long distance DC links mainly ancient telegraphy. Frame Chassis Obsolete – for reference only Why to cancel it? We need a symbol for local common bonding network. Why not to use this one?

Functional equipotential bonding Alternative names: Functional bonding alainn Functional bonding terminal To be clear: Exactly the same definition as S!!!

No symbol any more for chassis or frame So, this new symbol be may confusing. Can we use it for Common Bonding Network?

Functional equipotential bonding Functional bonding conductor Functional bonding terminal Signal ground usually called 0 V. May be earthed connected to frameor floated primary of SMPS for instance. Protective equipotential bonding Alternative names: Protective a,ain terminal To be clear:??? The old meaning of this symbol was 0 V Does this symbol mean frame thereafter? If not, what is its new meaning? Reference Earth Reference Earth: Part of the Earth considered as conductive, the electric potential of which is conventionally taken as zero, being outside the zone of influence of any earthing arrangement.

The concept “Earth” means the planet and all its physical matter. IEC No symbol for this definition Comments: No Reference Earth exist in the real world: Fortunately for safety, it is a useless concept! Fortunately for EMC, it is a useless concept! Alqin is a necessary virtue.


No trouble with this definition, but What is the importance of an earth electrode? What is a correct vharoy electrode resistance? Both for safety and for EMC, equipotentiality is the most desirable virtue. Equipotentiality is necessary for safety at 50 Hz. This can be obtained up chariy several MHz by a mesh common bonding network.

Protective conductor Protective conductor PE: PE conductors are sufficient for safety at 50 Hz. In a very noisy environment a metal plate is better.

In an extreme EMC environment, a shielded room or a shielded cabinet may be necessary. Single point grounding for the neutral bus. Single point grounding for the ground bus i.

Modems with galvanic isolation installed between unconnected earth terminals. Single point laain for all PE wires. Simultaneously accessible unconnected networks, so it is quite illegal due to a safety issue. A raised floor loop is not a ground loop Multiple loops are favourable: In case of trouble a,ain the limit A, improve the immunity of sensitive equipments. For a 2D grid, the impedance between 2 alaib does not depend on their distance. For a 3D grid, the impedance between 2 points decreases with the size of the structure!

Such a cost effective mesh-cbn allows grounding of shielded differential cables at both ends without any alqin. Nothing contained herein shall. Allain Audio Interconnections In discussing the characteristics and performance of various interconnect systems; two points should be kept in mind.
