- How to Calculate size of Earting Conductor and Earthing Electrodes? // Earthing Calculation.
There are mainly 4 types of Earthing Systems in India, Plate Earthing, Pipe Earthing, Mat Earthing, and Rod Earthing.
Pipe earthing is one of the popular earthing systems in India that suits every soil type. Earthing in large-scale residential, as well as commercial areas, prevents mishappenings on account of electrical shock. It protects your building and the electric boxes that are home to different types of electrical wires or cables.
Pipe earthing is joining a steel pipe with the earth’s electrical conductors. An Iron and steel pipe can transfer fault currents in electrical systems efficiently.
Earthing involves discharging electricity to the earth via low resistance electrical cables to prevent voltage surges resulting from an improper earthing system. Short circuits are a result of loose insulation and may occur anytime. However, a grounding wire may prevent these damages that can also be easily removed by technicians later.
Types of Earthing In India:
Electrical grounding, also known as earthing, is done in several ways like housing, wiring, electrical device, and more. The different types of electrical earthing systems in India are:
1: Pipe Earthing
Pipe earthing is a common form of earthing in India that uses a steel pipe to connect with the earth’s electrical conductors. The size of the iron pipe depends on the soil moisture and the magnitude of the current. The soil’s moisture will decide the depth for the placement of the steel pipe.
2: Plate Earthing
Plate earthing is where a copper plate is distanced at 3 meters from the earth and vertically placed in the ground pit.
3: Mat Earthing
Mat earthing connects vertical and horizontal electrodes - a horizontal electrode represses the current generated due to a massive fault while the vertical electrode dissipates the current into the earth.
4: Marconite Earthing
Marconite earthing is the safest earthing technology that uses low-resistant copper earth electrodes that are specially manufactured to deliver a premium quality earthing system for solar power plants. It is a dark grey material that is mixed with cement and water to produce safe and secure earthing system.

Hello! Amazing video. I have a doubt why we have ASSUMED DC FAULT CURRENT as 1000 AMPERES? Thank you!
Great job sir. Thanks for this knowledge
Thank you 🙏
Great
Very informative video 👍👍👍
Sir solar plant designing ki poori series karwa dijiye please 🙏🙏
Ok let me check
Strip Resistance & Electrode Resistance are in Parallel so we can not add like (R1+R2) .... It should be added in parallel like (R1*R2/R1+R2).... Please clarify this...
Very informative vedio sir👍👍
Thank you 🙏
Very important topic Dear
Thanks 🙏
Sir I think there is a miscalculation in Total Earthing Resistance which is greater than 2 ohms (1.772+0.580=2.35), means we need 9 electrodes instead of 8.
yes there is a miss calculation at the last you add and check
Keep doing your good work bro
Thanks 🙏
Sir How you will get K factor is 81 i am not getting please explained
Nice video...👍👍
Thanks 🙏
how to calculate for an earth mat covered with infill material
Kya aap IEEE142 method se calculation bata sakte ho?
Ok I will make a video
Good job Raman keep it up bro video
Thanks i
Very good explanation
Thanks and welcome
Nice 👍👍
Thanks 🙏
Great Information......keep It up.....only use big size "Whiteboard"
Increase your video quality in your system
I was watching video @ 720p then also you should increase your whiteboard size....as you have crossed 1000 subscribers..... I think you should upgrade it....
Informative video 👍👍👍
Thanks 🙏
Sir conventional earthing ki calculation batau
what is the value of Ln
What is the value of LN in equation of resistance of electrode
That is anti log
@@solarfacts4242 how we can find ln value. you haven't talk about ln value
Electronic circuit me 1 ohm se adhik earth resistance hone per dikkat ati hai, keonki 20000se 80000 amp current 250 se 300mili second ke liye lightning current rahati hai .aise me hamare electronic circuit me bar bar kharabi aa jati hai.Elecyrical circuit to sadharan SPD aur sadharan earthing se kam chala leti hai.
Thanks for your input
Sir very good video. Sir can u tell what size of wire(mm) would be required from earth pit till earth bar located in equipment room?
If you want to do earthing for any equipment then it is normally 1/2 of the phase wire
Beta it's a wonderful information, can you please send me information about the copper plate size or weight of plate and size of earth wire come from 15 meter, depth of the pit 2mtr x 2mtr, I have 10 kW solar system (12 panels)
Raman sir if we have 3 ajb ( ie dcdb) then what will be the calculation?
Calculation will be same only value will change
Could you Please let me know same calculation for 6sq.mm , 1 core, Cu Cable or 16 Sq.mm, 1 core,Cu
Ok will do 👍
How to decide earthing pit value???
For electrical we can maintain 3 Ohm and less than that
Sir, 2mw ka string calculation kaise kare. Ispe ek video banaye
Bro, can you please explain for bs7430 standard
Sure we are going to put one new video on it
What if there is no junction box and strings are directly connected to input of inverter as now a days most inverters have separate input for each string?
So there will be DC SPD so please do Earting with DC SPD
Thank you so much sir
Most welcome
sir,
short circuit current 1000 How????pls explain how we calcuate it for DC? for Lightening?
This we have assure for the calculation.
For the short circuit current we have an other video you can go though and learn how to calculate fault current
Sir good explain please make book about solar education for all
sure and thank you
dear it is ok but you dont tell the value of ln and what is this
ln is Anti log value
Why you have considered 1000 Value as Fault current. how you have decided No. of earth Pits. Don't we need Separate calculation for AC, DC and LA as per Fault current. If possible Please help with these doubts clearification
Yes we need to calculate separate earthing for AC DC and LA
total earth resistance is not 1.84 ohm and its is 2.352 ohm. so this is more than 2ohm now we take 10 nos of earth electrode and resistance is 1.998ohm and less than 2ohm.
There is a written error
Also my video is to educate the method if you want to maintain 1 ohm you can do the calculation accordingly
VERY WELL EXPLAINED. PLEASE CLARIFY (1)COROSION ALLOWANCE IS MENTIONED BUT NOT UTILIZED ANY WHERE IN CALCULATION. (2) THE RATING OF EQUIPMENT IN CIRCUIT WHICH CREATES SHORT ARE NOT INCLUDED IN CALCULATION. (3) I FEELS THAT TOTAL RESISTIVITY AT THE TIME OF SHORT CIRCUIT SHOULD BE CALCULATED AND THESE SHOULD BE DIVIDED BY RESISTIVITY OF EACH EARTH PIT. REQUEST TO CLARIFY.
We have considered in design
great Video. For enphase Microinvertor based solar system how many earthing are needed? One LA and one for ACDB/Panel ?
3 Earting for small project
@@solarfacts4242 one for ACDB, one for panel and one for LA.
Right
The effective resistance of electrode and strip should be (RsxRe)/(Rs+Re) as the arrangement are connected in parallel not in series. And what about the role of current density(Id)
Current Will divide
All Electrode are in parallel & in series with Steel Strip of calculation is 1/8Re+Rs
Earthing measurements Excel or calculator milega sir
Yes going to upload my new video on it
सिर्फ बारिश के टाइम असोल्युशन लो हो जाता ये कैसा चेक
Please check this video already we have uploaded
How does an Isolation Fault occur in a solar system ? // How to Resolve Isolation Fault ?
th-cam.com/video/XFWMGhyIXS0/w-d-xo.html
Please tell formula for calculation of earthing electrode??
You can get in this video
How you have considered fault current as 1000A?
That you can calculate as per system fault current
I will make one more video on it 👍
Yes bro required for Ac we have calculated but for DC how we assume it's magnitude pls make a video for DC SC current pls
What is the value of Ln..?
Anti log
k factor provide please
Ok will provide the link of that file in discretion
Earthing alway copper. Why your a explain steel?
In this video you have assumed number of electrodes as 8. We need to check if the number of electrodes is adequate. The number of electrodes required is to be calculated based on the fault current that can be dissipated by an electrode. This is to be calculated from the Surface Current density of an electrode which will yield the surface area required to dissipate the Fault Current. From the total surface area required and the surface area of single electrode, we can calculate the number of electrodes required.
We are coming up
With one more video where we will discuss the current dissipated from electrode
50x6sqmm resistance value
now i dont understand you if you kept kept english as a medium of instruction it would be great
Sar solar project erection and commissioning testing parameter SMB inverter Transformer breaker video
Ok will make 👍
GI kya k-factor
That is mentioned
is this English? I can't understand much
Sorry will do one more video in English
English subtitle please sir
Sure
Pls. Share sir
1.772+.58=1.84 ohm ?? How? It shall be 2.352 ohm
By mistake
Recheck some factors. Normally 4 Pits are enough. Dia 57mm x 3 m pipe must be considered.
Ok
@@matiodesh I m also same confusion
Bhai transport plus liaising, 5 saal maintenance cost, discom walo ka cut😂 net meter, generation meter ka bhi cost add karo.....dint spread fake information....ground pe kaam karne ke baad actual cost pata chal jayegi 3kw ki😂😂
Esa kya fake hai sahab 😀🫢
