2. Earthing system - Wikipedia

   en.wikipedia.org/wiki/Earthing_system

   Electrical installations. An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.

4. Copper - Wikipedia

   en.wikipedia.org/wiki/Copper

   Copper. face-centered cubic (fcc) (cF4) Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity ...

5. Counterpoise (ground system) - Wikipedia

   en.wikipedia.org/wiki/Counterpoise_(ground_system)

   In electronics and radio communication, a counterpoise is a network of suspended horizontal wires or cables (or a metal screen), used as a substitute for an earth (ground) connection in a radio antenna system. It is used with radio transmitters or receivers when a normal earth ground cannot be used because of high soil resistance [1] or when an ...

6. Copper conductor - Wikipedia

   en.wikipedia.org/wiki/Copper_conductor

   Electrical conductivity is a measure of how well a material transports an electric charge. This is an essential property in electrical wiring systems. Copper has the highest electrical conductivity rating of all non- precious metals: the electrical resistivity of copper = 16.78 nΩ•m at 20 °C. The theory of metals in their solid state [7 ...

7. Electrical wiring in the United Kingdom - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_the...

   A long rod placed into the ground, bonding, with low impedance, the installation to Earth potential. Usually made from copper-clad, galvanised or stainless steel or copper, for corrosion prevention. There are other types of Earth bonding, such as: an Earth plate, an Earth mesh, or an Earth ring.

8. Grounding transformer - Wikipedia

   en.wikipedia.org/wiki/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. They let three-phase (delta connected) systems accommodate ...

9. Porphyry copper deposit - Wikipedia

   en.wikipedia.org/wiki/Porphyry_copper_deposit

   Porphyry copper deposits represent an important resource and the dominant source of copper that is mined today to satisfy global demand. [6] Via compilation of geological data, it has been found that the majority of porphyry deposits are Phanerozoic in age and were emplaced at depths of approximately 1 to 6 kilometres with vertical thicknesses on average of 2 kilometres.
