The company makes a good grounding system, not any kind of electrical installation
The main purpose of earthing systems is to provide a common reference point between sources of electrical energy. In order to protect us and our devices, the specialists have set the basic points in the grounding systems as follows:
– Stabilize the voltage in the ground
flows to the ground.
This is done by:
Earth Pit: It is a group of conductors or electrodes that are buried or inserted into the ground so as to provide good contact with the least possible resistance with the surrounding soil.
– Main Earting Lead:The main conductor that connects a group of electrical equipment and appliances to ground.
– Bonding lead:The conductor that connects the structure or enclosure of the appliance or electrical equipment to the main ground conductor
Functional grounding: It is the neutral point grounding of power transformers and the common points grounding of current transformers for operational reasons.
Static earthing: It is used for the purpose of ensuring the leakage of stable charges that are generated in containers, vessels and tanks as a result of the collision of hydrocarbon liquids with the walls of those containers, vessels and tanks during loading or unloading, as the availability of good grounding leads to the leakage of the generated charges to the ground And not to be dangerous effort on those containers, tanks and containers.
– Grounding for the purpose of lightning protection
General principles of terrestrial network design:
– Reducing the potential difference between the adjacent exposed metal parts, as well as between them and the earth on the other hand… and this is done by connecting equal voltage
(Equi Potential Bonding) (Touch & Step Voltage), thus protecting people from fatal shocks.
Reducing the impedance of the ground electrode
