WHAT IS
EARTHING?
The connection between electrical appliances and devices
with the earth plate or electrode through a thick wire of low resistance to
provide safety is known as Earthing or Grounding. Earthing System or Grounding
System in Electrical network is for safety purpose.
The Main objective of earthing system is to provide an
alternative path for dangerous current to flow so that the problem of electric
shock and damaging of equipment’s can be cured.Metallic part of an equipment
are grounded and if the equipment’s insulation fails than there will be no
dangerous voltages present in equipment box.
The circuit gets sorted and fuse will blow immediately, in
case the live wire touches the earthed case Particularly, it can affect the
magnitude and distribution of current in short circuits through the system and
the effects of the system are on equipment and people who will near to the
circuit.
Why you should have an Earthing System?This question is
generally arises, when you have all the right equipment’s, wires, socket and
well maintained electrical devices, Yet, why is there need of an Earthing
system.The Answer is very simple..Earthing system makesyour building
electrically shock free and gives you a safe place.Below are some of the points
which can easily make you think about earthing system.
1. Safety for Human Life, Electrical Devices and Building
• It saves the human life from danger of electrical shock which can cause death, by blowing a fuse
• Protects your electric equipment’s or devices
• It provides a safe path for lighting and short circuit currents.
2. Voltage Stabilization You know that electricity has many sources. As Every transformer considered to be a separate source.

And if there is not a point which will act as common point,
then it becomes more difficult to make a calculation between these sources.In
the Electrical distribution systems, Earth is the omnipresent conductive
surface, which makes it a universal standard for all electric system.
3. Over Voltage Protection Earthing System provides an alternative path in the electrical system to minimize the dangerous effect in the electrical system which happens at the time of lighting and unintentional contact with high voltage lines.
