When all metallic parts in electrical equipments are grounded then if the insulation inside the equipments fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is effectively shorted and fuse will immediately blow.

When the fuse is blown then the dangerous voltages are away. Filed under Uncategorized. About Jignesh. Parmar B. Tech Power System Control , B. E Electrical.

Nice to see u r aticle, its great and useful to other electrical engineers for their reference, i need to share and learn about the following points. Electrical clearance and creepage distance for air and oil medium, wat would be the minimum clearances required between two phase contacts and phase to earth clearance and phase to phase clearance inside the oil medium transformer oil and also outdoor with reference to study.

It is utilised by them as by converting into another form of energy or when earthed it will be nuetralised by earth potential as earth is always at zero potential. Why the Copper plate earth pit needed for neutral Earthing and G. I pipe earth pit needed for Body earthing? Sir, I have a small doubt regarding earthing of power transformer neutral.. Please reply thanks. Thanku very much Jignesh for of the share your experiance with us and we pray for you regarding u will share your expiriance with us and u go always boss.

I live in chennai in an apt where there are 11 flats and a transformer 3 phase, 1 neutral grounded inside the premises supplied by the electricity board. The local EB staff came and have strengthened the earthing on the transformer side.

They have also connected the neutral in the DB box of the transformer to the earth pit. On our side i. Pls confirm whether the advise is ok; specifically can we also ground the neutral on our distribution panel.

Thank you. Please concern Local authority for such type of connection. We have a dedicated 3-phase, 4-wire KVA transformer. As I told you in my earlier mail, we had major damages to our equipment-lift,lights, fans etc.

We measured the current at the consumer distribution panel and got the following values:. First measure Voltage between Neutral and Earth.. The current on the neutral wire at the Panel when checked with the clamp meter was 5. The voltage between Neutral and Earth at the Panel is 0 volt. On the Transformer Side: 1 Strengthen Existing Body earth on the transformer side 2 Prepare another earth pit on the transformer side and connect the transformer neutral to this pit.

Dear Sir Can you please explain me, with clear example of Star and Delta connection for a motor, why we use Star and Delta with a small ckt diagram.

Sir please give a reply to my mail. For my house wiring what are all the standards to be adhered for earth pit measurements, pipe standard and related things for safe earthing. SIRS, A. How will we choose the cable size in sqmm if only the ampere is given ,with out the help of any charts i mean like a thumb rule. I hope you will give me the answer.

How to make a good chemical earth pit. If not not disconnected then reading will be correct or not. Please reply. Thanks a bunch for sharing this with all of us you actually understand what you are speaking approximately!

Does the eathing condutor use for neutral of distribution transformer grounding depends on the size of distribution transformer, if it does than could you please help me to calculate the required size of earth conductor for transformers of different capacities such as kva,kva,kva,kva,kva. I will apriciate your earl reply. Thanks Mr. We are facing problem in one of office bldg — everyone enter in office experience shock if he touch another person or Laptop.

We checked earthing value which is 0. No Problem found in the same. What to do? However, I could not find any explanation, reasons towards this selection guidelines. Jigneshhai, please throw some light on this. Dear sir, Normally we follow the pipe earthing treated or non treated type depending upon the nature of job to be executed with a depth of 3. But sir is there any possibility of having a horizontal earthing for temporary basis with a depth of 0.

As i am facing this problem due to hard rock area and for pipe type earthing to follow we need to mae a bore, but due to some or the other delay. Sir please help. SIR, I wanted to know more about Chemical Earthing that is be installed in Hilly area where hard rocks are underneath. Plate size 1. Dear Dileep, It show both surface of Plate earthing because both surface of plate are with touch of soil so plate surface area would be double… I think this is enough clearness i may explain..

Can I have some detail as regards to the comparison of The Copper and GI with the cast iron plate or pipe electrodes and their conductivity values, my architect has been telling me about cast iron pipes a lot.

Is it earthing test point is mandatory for all down conductors or else we can connect it directly to earth pit. We r using C. Pipe of mm dia 3 mtr. We have seen that some of pipes get rusted in this mm portion after yrs. My queries are : If CI Pipes are kept in open air condition whether it gets rusted by naturally, if not what is the reason?? Is there any affect in earthing due to this rusting?? How to overcome from this rusting if pipes are already erected??

We had a problem recently.. When we measured neutral to earth and phase to neutarl voltages al found ok. AVR of DG is also foundok. Jignesh bhai l want to need to talk about earthing rod,actuliy l want to start manufacture earthing rod with back fill compound so that l need your help for information how l start this project.

Plz send mail and l need to talk to you one time plz ek war vaat jarur karjo. I have confusion about calculation of plate earthing,weather the formula is correct. If so example calculation is wrong please check. Is there any special requirement of Earthing for Operation Theater? Doing feet hole in earth of 2inch and filling it with feet copper wire with sand is.. Correct for of Earthing? Is oscillation transformer usefull to bring down to zero ampere where traditional earthing pit is not working..

Sir, How do we provide earthing for a system on water body, say for eg. Dear Sir can we bound together all LV neutral of sub station i. Dear Parmar, we are facing a problem in our glass coating machine of power rating kw, the value that we maintain between neutral and earth is 0. Dear Jignesh sir, Thanx for such a nice thread. I want to know why double earthing is used in case of 3 phase system? It is good to know about earthing. If I will receive the article like that on my email this is good to me.

Hi Mr. Pramar, First of all thanks alot for your valuable information. Jignesh bhai, i have a some odd problem, i have pulled a line from LT transformer which is meters away, theirs a peculiar voltage problem, My voltage reads as volts but when i start my submersible pump 1.

Just simply explain what is earthing in layman language in about lines. Dear sir what is solution if there is only 4 feet depth for conventional system earthing ,what is the effect if we continue with lesser depth for earthing. Hi Jignesh. If so, why? Is there any difference between the electrical earthing and body earthing?

Hi Jignesh I need to earth my Wind Turbine installation. Problem I have is that the turbine is installed on a rocky outcrop. I cannot drive in a spike or dig any substantial hole anywhere near the location.

What is Earthing
