What Is Earthing? | What Is Electrical Earthing System? 

Earthing is meant to be carried out by digging 2.5 to 3 meters deep into the ground, to make a pipe or plate piece of copper or galvanized iron in it.

Or The Direct Connection Of The Metal Body Of The Electrical Device To The Ground Through The Integrity Wire Is Called Earthing System . Which Is Also Called Grounding. 

Indian Electricity Rules To Any Metalliferous Body Of Every Tool In Electrical Installation 1956 Earthing Is Mandatory.

The Reason Is That The Circuit Acts As A Safely Device Like Fuse In The Circuit .

Similarly, Earthing Also Acts As A Protective Tool For That Installation And The Person Working On That Installation. Below Are Some Of The Main Reasons Why Earthing Is Very Important. Importance Of Earthing

Human Life Should Be Protected From Electric Shock.

Power Generators, Alternators And Power Distributing Transformers Are Paired With Neutral Earthing.

The Ground Is A Conductor Of Electricity. When The Phase Wire Or Positive Conductor Of The Supply Is In Contact With The Body Of The Electrical Device, An Electric Current Starts Flowing In The Body Of That Device.

If Work On The Stand At A Man On The Ground In This Case That Device, The Contact Flow In The Body Of The Device Current Is.

And That Person Feels Electric Shock .

If The Body Of The Device Is Connected To The Wire. Then The Phase And Earthing Are In Contact.

The Circuit Of The Instrument Is Converted Into A Short Circuit . Due To The Circuit Short Of That Device, More Current Flows In It.

That Current Also Flows Through The Fuse Installed In That Circuit. As A Result, The Fuse Wire Of That Fuse Breaks Due To Excessive Current.

The Circuit Of That Device Turns Into An Open Circuit . And Thus Further Potential Living And Finance Losses Are Avoided.

To Protect Equipment Or Installation Due To Leakage Current.

If The Insulation Of A Wire Or Cable Is Of Low Capacity, Then Later Its Insulation Resistance Capacity Decreases Further . Due To This, Leakage Current Flows From The Insulation Of The Wire Or Cable, Which Keeps Coming In And Moving In The Metal Body Of The Device.

This Causes The Body Of The Device To Become Hot. If There Is More Leakage Current Then The Body Becomes More Hot. Winding Of The Device Is Likely To Cause Burns Due To The High Temperature. Bearing May Be Defective.

If The Device Is Connected To The Earthing System In This Situation, Then Leakage Current Runs Through The Ground Through The Wire. And The Ill-Effects Occurring Are Averted.

To Protect The Sky-High Buildings, Large Electrical Equipment And Over Head Lines.

Overhead Line, Genrating Station, Substation And High-Rise Buildings, If All The Lightning Falls, They Can All Be Destroyed By Burning. Therefore, On High Buildings, Earth Conductor And Over Head Line Are Attached To The Earthing System By Placing Lightning Arrester On It . Sky Electricity Enters The Ground Through The Earth Conductor. And Thus Because Of Earthing All These Are Safe.

What Is The Difference Between Neutral And Earthing?

From The Above Mentioned Findings, It Proves That The Earthing System Is A Means Of Protection. Reason: Neutral Located In The Circuit Completes The Path Of Current Flowing In The Circuit.

So Earthing Completes The Path Of Leakage Current. Neutral Is A Caste Associated With Load Resistance , So The Earthing Device Is Attached To A Metalized Body.

Neutral This Circuit Is Used For Closing And For The Return Path Of Current, Then Earthing Is Used As A Means Of Protection To Leak Leakage Current.

Earthing At These Places Is Very Important When Using Electricity.

  1. All Switches, Distribution Box, Busbar Chambers With Metal Body To Their Body.
  2. Electric Motor, Transformer His Body At Least 2 Places.
  3. Electric Iron, Heater, Geezer, Cooler’s Body.
  4. Big Long Terminal Of Tree Pin Socket.
  5. Star Point In The Three Phase Four Wire System.
  6. Neutral Conductor In DC Three Wire System.
  7. Underground Cable Armoring.
  8. Every Metal Conduit In Conduit Wiring.
  9. And According To Indian Electricity Rule 90, The Pole Of The Over Head Wire Should Be Earthing At Least 4 Places Every 1.6 KM.

Earthing System Rules Of ISI On The Subject (ISI Rules Regarding Earthing)

  1. Outside Of Any Building, Earthing Should Be Done At A Distance Of 1.5 Meters From The Building.
  2. Earth Electrode And Earth Conductor, Nut-Bolt And Washers Should All Be Of The Same Metal.
  3. Earth Conductor Should Have Twice The Current Current Carrying Capacity Of The Circuit.
  4. The Mean Conductor Size Of Any Circuit Should Not Be Less Than 14 SWG. The Main Means Conductor Shall Not Be Less Than 8 SWG.
  5. The  Mechanical Conductor Of The Earthing System Should Not Cause Mechanical Damage, So It Should Reach 60cm Below The Ground Where It Is Required Through A 12mm Diameter Pipe.
  6. Salt, Sand And Coal Should Be Laid Layer By Layer At An Interval Of 15-15 Cm Around The Earth Electrode.
  7. Earth Conductors Should Be Used Only With The Help Of Joint Nut-Bolt And Washers. And Soldering On That Joint Later
  8. Resistance Of Earthing Should Always Be Minimal. Earth Conductor Should Not Be More Than 1 Ohm If It Is Of Copper And 3 Ohm If It Is Of GI.
  9. In Order To Reduce The Earth Resistance During The Summer Days, Water Should Be Poured In The Funnel In Between.
