An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipment's conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.
Conductive mats are made of carbon and used only on floors for the purpose of drawing static electricity to ground as quickly as possible. Normally conductive mats are made with cushioning for standing and are referred to as "anti-fatigue" mats. 3 ply static dissipative vinyl grounding mat shown at macro scale
In electrical engineering, earth potential rise (EPR), also called ground potential rise (GPR), occurs when a large current flows to earth through an earth grid impedance. The potential relative to a distant point on the Earth is highest at the point where current enters the ground, and declines with distance from the source.
Typical resistance is on the order of 10 5 to 10 8 ohms between points on the mat and to ground. [11] [12] The mat would need to be grounded (earthed). This is usually accomplished by plugging into the grounded line in an electrical outlet. It is important to discharge at a slow rate, therefore a resistor should be used in grounding the mat ...

A grounding transformer. A grounding transformer or earthing transformer is a type of auxiliary transformer used in three-phase electric power systems to provide a ground path to either an ungrounded wye or a delta-connected system. [1] [2] Grounding transformers are part of an earthing system of the network.
For building electrical grounding systems or earthing systems, there is a low resistance conductor bonding the metalwork and this is connected to a groundbed. The electrodes for electrical grounding are often called ground rods and are often made from steel with a copper clad surface – typically 1 to 2 m long and 20 millimetres (0.79 in) in ...
[1] [2] The electrode is usually located several tens of kilometres from the converter station in order to avoid possible problems or corrosion in the converter station grounding system. [3] The electrode line connects the converter station to the grounding electrode. The electrode line can be implemented, depending upon the location of the ...
