definition:Lightning is a flash of bright light in the sky which is produced by electricity moving between clouds or from clouds to the ground.
so as we know already lightning is of two types direct and indirect lightning.
These are anyway a discharge of electricity either positive or negative potential just discharges to ground known as lightning.
definition:to put an earth wire between a piece of electrical equipment and the ground.
Where as earthing is manually or artificially done to discharge any potential either to prevent any over voltages such as lightning or fault currents etc.,

The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What is meant by earthing?
The same as 'grounding' , putting a wire or metal stake into the ground so something attached to it has the same electrical potential
What is a difference between neutral earthing and body earthing?
here is no major difference between earthing and Grounding, both means "Connecting an electrical circuit or device to the Earth". This serves various purposes like to drain away unwanted currents, to provide a reference voltage for circuits needing one, to lead lightning away from delicate equipment. Even though there is a micro difference between grounding & earthing.Earthing and Grounding both is refer to zero potential but the system connected to zero potential is differ than Equipment connected to zero potential .If a neutral point of a generator or transformer is connected to zero potential then it is known as grounding. At the same time if the body of the transformer or generator is connected to zero potential then it is known as earthing.

Lightning protection grounding materials bear the burden of our lightning protection and lightning protection, as lightning protection grounding materials electrolytic ion grounding, in lightning protection grounding has a pivotal role, ion grounding as lightning protection grounding materials, in various geological environments are widely used, especially in the high resistivity of the soil and construction of difficult places so is known as lightning protection grounding in the product. Ion grounding materials are copper clad steel, galvanized, purple copper, pure copper. Ion grounding content is one of the factors affecting the grounding resistance, many soils contain active electrolytic ion compound more, simple grounding body will not meet the grounding requirements. After experimental comparison, reversible slow-release filler is added to the grounding. This filler has the characteristics of water absorption, water release and reversibility. This reversible reaction, effective The effective temperature of the environment within the shell layer, the stability of the grounding resistance. The filler side effect, in the role of long-term cooperation with metal electricity, in the ion grounding generation and the copper alloy to prevent corrosion of both aspects have achieved a better effect. After the ions generated in this way absorb the earth moisture, the active electrolytic ions can be effectively released into the surrounding soil through the effect of deliquescence, so that the grounding becomes an ion generating device, thus improving the surrounding soil quality to meet the grounding requirements.

How heavy is the wire used to direct lightning off of a lightning rod?
The electrical code states "The bonding or grounding conductor shall be of copper not smaller than No. 6 AWG." when it comes to lightning arresters. Also it is paramount to keep the length of the grounding conductor as short as practicable to guarantee the effectiveness of the protector. It is suggested that the length of the grounding conductor be limited to 6 metres maximum. If you have access to an electrical code book look up "lightning arresters" as there is much discussion on the subject and I am sure that you will want to do the job correctly.
Classification, basic concepts and installation of grounding devices?
Grounding device is also called grounding integration device: a device that forms an electrical connection between electrical equipment or other objects and the ground. (Building Electrical Construction Technology). The grounding device consists of a grounding electrode (plate), a grounding busbar (indoor and outdoor), a grounding down-conductor (grounding jumper), and a frame grounding. It is used to realize the purpose of connecting the electrical system to the earth. The metal object that is in direct contact with the ground for electrical connection is the ground electrode. It can be an artificial ground electrode or a natural ground electrode. This grounding electrode can be assigned some electrical function, such as being used as system grounding, protective grounding or signal grounding. The grounding busbar is the reference potential point of the electrical installation of the building, through which the part that needs to be grounded in the electrical installation is connected to the grounding electrode. It also serves another function, that is, by interconnecting the equipotential bonding lines in the electrical installation, the overall equipotential bonding between the large conductive parts of a building is realized. The connection line between the grounding electrode and the grounding busbar is called the grounding electrode lead. Safety isolating transformer safety isolating transformer. Transformers that supply tools, other equipment and distribution circuits with safe extra-low voltage. Its input winding and output winding are electrically isolated by at least the equivalent of double insulation or reinforced insulation. Next, an excellent grounding device manufacturer, Sichuan Sunlight intelligent electric equipment Co., Ltd, will introduce the classification of grounding devices, basic concept of grounding device resistance and installation of grounding device. Classification of grounding devices The grounding device is composed of a grounding body (round steel, angle steel, flat steel, steel pipe, etc.) buried in the soil and a grounding wire for connection. According to the purpose of grounding, the grounding of electrical equipment can be divided into: working grounding, lightning protection grounding, protective grounding, and instrument control grounding. Working grounding: It is the grounding required to ensure the normal operation of the power system. For example, the neutral point of the transformer in the neutral point direct grounding system is grounded, and its function is to stabilize the potential of the power grid to the ground, thereby reducing the insulation to the ground. Lightning protection grounding: It is the grounding set for the needs of lightning protection. For example, the grounding of lightning rods (wires) (now called lightning rods, wires, strips) and arresters is to make the lightning current smoothly lead to the ground, so as to reduce the lightning overvoltage, so it is also called overvoltage protection grounding. Protection grounding device: also known as a safety grounding device, it is a grounding device set up for personal safety, that is, the electrical equipment shell (including the cable sheath) must be grounded to prevent the shell from being charged and endangering personal safety. Instrument control grounding device: the thermal control system, data acquisition system, computer monitoring system, transistor or microcomputer type relay protection system, and telecontrol communication system of the power plant, etc., are set up to stabilize the potential and prevent interference. Also known as an electronic system grounding device. The above is the classification of grounding devices. basic concept of grounding device resistance The resistance of the grounding device refers to the resistance encountered when the current passes through the grounding body into the earth and spreads around. The earth has a certain resistivity, and if there is current flowing through it, the earth has different potentials everywhere. After the current is injected into the ground through the grounding body, it spreads around in the form of a current field. 15~20m away), the resistance per unit diffusion distance and the current density in the ground are close to zero, and the potential here is zero. The curve U=f(r) in the figure represents the potential distribution on the ground surface (r represents the distance from the lightning current injection point). The above is the basic concept of grounding device resistance. Installation of grounding device
Electrolytic Ion Grounding Composition And Installation Location?
Ion grounding selection of cold-drawn yuan steel, with equipment outside the casting of purple copper (thickness of 0.3 ~ 0.5MM), to its excellent electrical conductivity and mechanical strength, the product has excellent anti-corrosion properties. Electrolytic Ion Grounding Electrolytic ion grounding composition ● Connection tube Rod and rod can be connected by copper connection tube, with good effect. The contact between the rod and the rod is so tight that the driving force acts directly on the rod when the grounding rod is driven into the ground or drilled into the ground with a driving drill. There are threaded connections and non-threaded connections. ● Drive head Made of alloy steel, it can drive the force into the ground smoothly. Ion grounding is driven into the ground under complicated geological conditions. Copper clad steel grounding rod for grounding network in the vertical grounding body, grounding in the entire lightning protection system occupies an important role, it affects the entire lightning protection system against direct lightning effect, direct lightning through the lightning rod / lightning belt and other lightning devices, and then through the grounding network into the ground, the grounding network of good or bad affect the overall effect. In foreign countries have used copper-plated grounding rod (copper clad steel grounding rod) instead of galvanized round steel, precisely because the effect of copper-plated grounding rod is several times higher than galvanized round steel. Copper clad steel grounding rod is electrolytic copper plating to the steel surface, high bonding without gaps, any bending will not produce copper layer stripping phenomenon, and because the surface of the round steel is high purity electrolytic copper, ion grounding so copper-plated grounding rod conductivity can be comparable to pure copper, is now the preferred grounding material for power engineering, petrochemical engineering, communications engineering, etc. The installation position of electrolytic ion grounding Ion grounding installation position especially when equipped with multi-level power supply lightning protection is very important, if not carefully considered, may be selected according to the technical requirements of the ion grounding is not very good protection. Both a waste of money. And left a lightning accident potential. This is due to when the overvoltage wave transmission along the cable, the protected equipment and the power supply lightning protection device between the energy reflection. This reflection phenomenon and the characteristics of the power supply lightning protector at all levels, the characteristics of the equipment being protected and the characteristics of the cable between them. It can cause overvoltage on the protected equipment that far exceeds the residual voltage on the power surge protector, and may be fed back into the power system to produce a bad effect.

How do lightning rods protect structure?
well a lightning rod will help a structure by channelling the lightning round the structure rather than on it and it will send the lightning into the ground so it cant hurt anything/anyone a simpler explanation would be that it channels the lightning away from the structure oh by the way I am 12 years old
