Hlo sir
Sir hum 1.8 mw DC capicty ka solar system installed krwa rhe hai
14 inverter hai 100 kw ke har inverter me 9 string hai or ISC 18.5 amp hai
To sir earring calculation bataiyega llz sir
R2 is in parallel with R1 why because we are connecting the earth strip to earth pit at 2 different points.
Right?
Please also make a video on overall earthing of solar power plant
Sure very soon
Sir, pls provide me excel link for calculation
How to download this file
Hi text me on LinkedIn from video discription
please Share Excel file
Please ping me on LinkedIn or Instagram from video discription
Please prepare one clip on Topcon Technology of PV
Corrosion factor value calculation no idea
Pl send excel sheet
Connect with me from video discription
Hi sir this side Neha Shukla I saw your video solar earhing dc calculation but I have doubt like if you take conductor size A=0.5637mm2,so why you move standard value available in market 25*3Gi strip if you want maximum 2mm2conductor So why you take gi strip of 25*3?
If I am not mistaken NEC and NFPA standards dictate common earthing not AC and DC earth separate. In case of Lightning discharge due to different potential gradient on ground, different earthing may result equipment damage or fire. What reason NEPRA give to have them separated. Please Explain. Now you are saying BS also follow a common earthing.
Sir exal sheet chaiye
Sir exal sheet chaiye
Does the "width or breath" of the "pit hole" makes any difference to the final achievable earthing values ? I saw some earth pits of 50mm (done by an earth auger) with 12.2mm dia electrode. Is that correct to do like this ?
the pit civil work has no correlation with pit resistance value - its main aim is to protect the joint between the electrode & earth strip from physical hit , and could be easily maintained to check earth value , or allowing water to enter the pit.
please send me exel sheet
Please share excel sheet

Sir for MW plant ke liye same calculation hai kya
Yeh. Chahiye.. File
Hi
Can you pls send me the this ex el sheet along with other calculation sheets bro.
I tried message u in LinkedIn,but not able to send it
Sir why inverter body is connected to DC side Earthing.pls reply.I asked to many people all are replied me to connect to AC earth
Sir 12v,24v,36v and 48v solar inverter me 12v 100wp solar panels wearing keysa karu?
375*3 solar system ke liye kitne sqmm ka wire chaye (Normal dc wire ya solar special wire).
Normal 4sq mm
Sir jiii ..plz make a video on transformer maintenance ... plz plz
Definitely
Great sir
Sir please give me earthing calculation dc
Hi , follow the instructions in the discription
Please make a video with calculation sheet for ac side earthing and LA earthing
Sure
Please calculate the 1 Mw SPP earthing calculation as an example .
hi sir,i have one question regarding the conductor sizing in the video @7:30mnts you are saying about the short circuit current of different material for 1s & 3s. in a pv system we dont have any safety or cb which will disconnect the short circuited strings from the start point of cable from string then if short circuit happen the current will flow for more than hours till we will open the MC4 of faulty string, in this case our selected conductor will overheat and burnt so kindly guide how we can select proper conductor size. sir 1s and 3s material current capacities for substation system where we have proper protection system which can detect the fault current and disconnect the faulty line from system.
Hi Asif , here the value t is the operating time of the device getting disconnected due to insulation fault , which is the Inverter ,
Whenever the dc cable gets an insulation fault the inverter trips automatically and the string becomes an open circuit in a fraction of seconds
@@SustainableEveryDay sir our power source is string if i have a length of 280m 2run of 4mm sq for negative and same for positive if cable get damaged at 150m then how string side will be isolated.at inverter side during short circuit string voltage will be zero and may inverter will disconnect the string.
Tq
Sir can we link LA Earth to dc side earth
No
Sir can you please tell me, what should we keep the standard distance between each and every earthing pits?
3.5 to 4m space between 2 earth pits
Hello sir.. Thank you for this good video. Can you share the calculation sheet.
Sir send me battery calculation charging and discharging in solar power plant
How to decide DC capacity of plant as we have to design 100mw AC plant?
Thanks sir it is very help to us sir plz do one vdeio . Lt ac side earthing sir
Hy please send the excel sheet.sir.
Check description
Ek video banaiye sir 5 kw mei kitne kitne ka casting Banega 10 kilowatt mei kitne kitne ka string hoga
please excell sheet share me
Hi please text me on LinkedIn I will share
In Earthing strip formula, "W" is depth of GI pipe or Earthing Strip ...???
Width of GI pipe
@@SustainableEveryDay but You have mentioned "W" is for length of GI pipe
Hi , W is the depth of GI rod burried in the groud i.e the lenght of GI pole , , I have taken it 300cm I e 3m , I got confused , for your 1st question ,
@@SustainableEveryDay Thanks😊
Can I get this sheet for my reference
Hello, your vedio is useful. My question is the dc side earthing and ac side earthing connected together or isolated?
Isolated always
@@SustainableEveryDay in this video you have created 4 pits for four strips for almost 100-150W Solar Panels. It is completely illogical. It will be a home system with these panels and four pits for a single home.. completely insane.
A proper home work sir. It is trouble some in some houses to find the proper place for 3 earthing,what to do in this case . On road side ,narrow lane,pipe line gas line ,cables drainage,
My question is either to install system or nor and either to do one earthing .As I know distance from wall is 1m please share as your advice commercial and as technical.
See if you don't have space for multiple earthing for domestic purpose , then do one earthing only 4m deep using earthing chemical compound , and try achieving 3ohms resistance.
For commercial space is never a issue because they need to follow DISCOM guidelines in order to get approval.
Bhai yeh app send kar de plz
It's an excel sheet , please msg me on LinkedIn
Please share the excel formula sheet. Thanks

How do you maintenance the earth resistance value in desert area & what earth pit resistance value you have maintained in your solar plant?
In desert area the depth goes to 15- 20 feet , using bentonite + chemical to get the lower vslue
Thank you sir for sharing your expertise . Will you please suggest good platform for solar pvsyst and autocad certification site where I will get certification at the end of course?
There is nothing as such , both software is all about daily usage , more you use better you understand
@@SustainableEveryDay ok sir thank you
Please use English
Sir can u please share me the Excel sheet, souvikh06@gmail.com
Hii Himanshu .
All you videos are amazing and very informative.
But i felt there are some shortcomings in this video which i would like to point out.
Calculation for determining earthing electrode no.
Current Density At The Surface of Earth Electrode (As per IS 3043) Calculation
Max. allowable current density I = 7.57×1000/(√ρxt), A/m2
Max. current dissipated by one Earthing Pipe = Current Density x Surface area of electrode
Number of earthing pipe required = Fault Current / Max.current dissipated by one earthing pipe.
In addition to this I request you to cover the following points if you are making any further video
1. Types of earthing electrodes used & Changes in the formula ( pipe/rod etc)
2. The video covers earthing strip current rating variation with material. Is there similar case with earthing electrode(GI/ Cu) too ?
3. Other Common Sizes of Earthing strip used if 25* 3 fails ? Should we use 25* 6 or any other size ?
4. Also plz cover AC Earthing
In case of string inverters, fault current is limited to Isc of strings paralleled on a single MPPT. Correct me if I'm wrong.
Very knowledgeable videos of yours
Hello sir,
Can you share plate earthing calculation...??
