Earthing Systems vs Electrical Grounding – Difference between Earthing and Grounding


One of the most misunderstood and confused
concept is difference between Grounding and Earthing. There 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. In this video we will go to show you difference
between earthing and Grounding. Earthing means connecting the dead part (the
one which does not carry current under normal condition) to the earth. For example electrical equipment frames etc. Grounding means connecting the live part (the
one which carry current under normal condition) to the ground. For example neutral of transformer, 3- ph
star connection etc. Earthing work in under fault condition these
parts may attain high potential earth. so any living being touching these parts will
be subjected to potential difference which may result in flow of current of such a value
which may prove to be fatal. Grounding is done for protection of power
system equipment and to provide a effective return path from the machine to the power
source. Earthing is to ensure safety or protection
of electrical equipment and living being by discharging electrical energy to earth. During lightening dangerous high voltage can
develop in the electrical distribution system wires. Grounding provides a safe return path around
the electrical system of your house thus minimizing damage from such occurrences. Dear sir, Thanks for watching the video. For more update please subscribes our channel
