RIG Earthing Solutions conceived its business operation in the year 2005 as a firm in the industry. We are engaged in the business of manufacturing, supplying and service providing for qualitative range of Earthing products.
Chemical Earthing Electrode Chemical earthing is an earthing in which we use chemical powder instead of salt and coal. Chemical earthing is maintenance free earthing In any ordinary earthing, salt and coal are placed on top of the electrode. When the chemical earthing, the chemical powder is placed over the electrode. Two types of powders are used in chemical earthing. One is Carbon powder and the other is Bentonite powder. Carbon powder is black in color while bentonite powder is brown in color. Type of Chemical Earthing 1) Galvanized Iron Earthing Pipe 2) Pure Copper Earthing Electrode 3) Copper Bonded Earthing Rod 1) Why Galvanized Iron Earthing Pipe: Because of its electrical characteristics and reasonably low price , galvanized iron also can be considered as an alternative to copper as a grounding material . In this paper, evaluation is being done in order to verify the performance of stranded galvanized iron as gr...
The
process of Earthing or electrical grounding can
be done in several ways like wiring in factories, housing, other machines, and
electrical equipment. The different types of electrical earthing systems
include the following.
Plate Earthing System
In
this type of system, a plate is made up of copper or GI (galvanized iron) which
are placed vertically in the ground pit less than 3meters from the earth. For a
better electrical grounding system, one should
maintain the earth moisture condition around the plate earthing system.
Plate Earthing
Pipe Earthing System
A
galvanized steel based pipe is placed vertically in a wet is known as pipe
earthing, and it is the most common type of earthing system. The pipe size
mainly depends on the soil type and magnitude of current. Usually, for the
ordinary soil, the pipe dimension should be 1.5 inches in diameter and 9feets
in length. For rocky or dry soil, the pipe diameter should be greater than the
ordinary soil pipe. The soil moisture will decide the pipe’s length to be
placed in the earth. The pipe earthing diagram is
shown below:
This type of earthing system is similar to
pipe earthing system. A copper rod with galvanized steel pipe is placed upright
in the ground physically or using a hammer. The embedded electrodes lengths in
the earth decrease the resistance of earth to a preferred value.
This is all about what is meant by earthing / definition of earthing and
its types. From the above information, finally, we can conclude that the
earthing system or electrical grounding system offers greater
safety from electric shock for personal, equipment, buildings, etc. The ground
sensitivity can be The earth resistivity can be affected by some issues like
soil and climate, a condition of resistivity, moisture, melted salts, earth pit
location, physical work, grain size effect, current magnitude, etc. Here e is a
question for you, what are the benefits of electrical earthing?
The
electrical equipment mainly consists of two non-current carrying parts. These
parts are neutral of the system or frame of the electrical equipment. From the
earthing of these two non-current carrying parts of the electrical system
earthing can be classified into two types.
·1) Neutral
Earthing
·2) Equipment
Earthing.
Neutral Earthing
In
neutral earthing, the neutral of the system is directly connected to earth by
the help of the GI wire. The neutral earthing is also called the system
earthing. Such type of earthing is mostly provided to the system which has star
winding. For example, the neutral earthing is provided in the generator,
transformer, motor etc.
Equipment Earthing
Such
type of earthing is provided to the electrical equipment. The non- current
carrying part of the equipment like their metallic frame is connected to the
earth by the help of the conducting wire. If any fault occurs in the apparatus,
the short-circuit current to pass the earth by the help of wire. Thus, protect
the system from damage.
Importance of Earthing
The earthing is essential because of the following
reasons
·The
earthing protects the personnel from the shortcircuit current.
·The
earthing provides the easiest path to the flow of shortcircuit current even
after the failure of the insulation.
·The
earthing protects the apparatus and personnel from the high voltage surges and
lightning discharge.
