Pipe earthing is the most common type of earthing. In this method as well, the earth pits are filled with alternate layers of charcoal and salt for inducing reactivity. The length and diameter of the pipe depends on the type of soil and the type of electrical installation.

The pipe is drilled with holes for connecting the earthing wires. These earth pits are then filled with charcoal and salt in alternate layers.įor pipe earthing, a pipe of galvanised steel is placed in the soil instead of a plate. Plate earthing requires a copper or galvanised iron to be buried vertically into the earth in an earth pit, dug more than 10 feet into the ground. The earth is an ever-present conductive surface and helps configure these relationships between different electrical sources and makes them easier to handle. An electrical circuit has to be connected together with a lot of attention to the kind of reactions each transformer may have in response to any action on the part of any other transformer.When earthing is installed with the electrical installations, the current is routed through a different path and does not affect the electrical system. These kinds of overload can lead to damaging of devices and danger to human life. In cases of surges in the voltage, high voltages can pass through the electricity circuit.This is done by providing a separate path for this faulty current, enabling its immediate detection and stoppage. Though metal is a good conductor of electricity, proper earthing ensures that metal parts not meant to be used for current transfer can be included in the system. Another advantage is that metal can be used in electrical installations without having to worry about conductivity.The potential of the earth is zero volts and is known as the neutral of the electricity supply. The electrical system is related to the potential of the general earth mass and cannot reach a different potential.It prevents the risk of fire that could otherwise be caused by current leakage Advantages of earthingįrom a technical perspective, earthing has some excellent advantages, resulting it in becoming a mainstream practice in the electrical industry.It prevents damage to electrical appliances and devices by preventing excessive current from running through the circuit.
