Hello! Amazing video. I have a doubt why we have ASSUMED DC FAULT CURRENT as 1000 AMPERES? Thank you!

Please make video on selection of MCCBs if one panel has may MCCBs like Main MCCB and sub circuit MCCB how to select rating for all

[@ADIL-xt3lu]

Can you please tell how we can take fault current on the AC side by thumb rule?

[@rajaanzar6871]

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.

[@solarfacts4242]

yes there is a miss calculation at the last you add and check

[@khanKhan-xh2we]

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?

[@solarfacts4242]

If you want to do earthing for any equipment then it is normally 1/2 of the phase wire

[@viveksangapal8084]

Great Information......keep It up.....only use big size "Whiteboard"

[@solarfacts4242]

Increase your video quality in your system

[@viveksangapal8084]

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....

[@Mikku7Vlog]

Raman sir if we have 3 ajb ( ie dcdb) then what will be the calculation?

[@solarfacts4242]

Calculation will be same only value will change

[@sattarqazi3785]

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)

[@SamorEarthingBoringserviceLaho]

Great

[@sandeeppatidar025]

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...

[@harilalyadav5057]

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.

[@solarfacts4242]

Thanks for your input

[@dilipgajjar5024]

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.

[@solarfacts4242]

We have considered in design

[@manjunathgondi1400]

Sir good explain please make book about solar education for all

[@solarfacts4242]

That is anti log

great Video. For enphase Microinvertor based solar system how many earthing are needed? One LA and one for ACDB/Panel ?

Bro, can you please explain for bs7430 standard

Sir conventional earthing ki calculation batau

sir, short circuit current 1000 How????pls explain how we calcuate it for DC? for Lightening?

[@solarfacts4242]

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

Could you Please let me know same calculation for 6sq.mm , 1 core, Cu Cable or 16 Sq.mm, 1 core,Cu

[@solarfacts4242]

Ok will do 👍

[@irshadhussain6228]

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?

[@solarfacts4242]

So there will be DC SPD so please do Earting with DC SPD

[@digitalcreator1793]

How to decide earthing pit value???

[@solarfacts4242]

For electrical we can maintain 3 Ohm and less than that

[@sujitgangaware1885]

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

[@solarfacts4242]

Yes we need to calculate separate earthing for AC DC and LA

[@rajeevranjan3124]

what is the value of Ln

[@DeepakChauhan-zl9cu]

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)

[@solarfacts4242]

Current Will divide

[@Ebuilt]

All Electrode are in parallel & in series with Steel Strip of calculation is 1/8Re+Rs

[@siligurisolarstation2310]

Earthing measurements Excel or calculator milega sir

[@solarfacts4242]

Yes going to upload my new video on it

[@NikhilKumar-hg7xc]

How you have considered fault current as 1000A?

[@solarfacts4242]

That you can calculate as per system fault current

[@solarfacts4242]

I will make one more video on it 👍

[@engineerengg9427]

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

[@murali1802]

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.

[@solarfacts4242]

We are coming up With one more video where we will discuss the current dissipated from electrode

[@nitinkumarsahu4435]

Please tell formula for calculation of earthing electrode??

[@solarfacts4242]

You can get in this video

[@mdazhar8570]

What is the value of Ln..?

[@solarfacts4242]

Anti log

[@RaghunathPrasad-ov9ce]

dear it is ok but you dont tell the value of ln and what is this

[@solarfacts4242]

ln is Anti log value

[@RaghunathPrasad-ov9ce]

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.

[@solarfacts4242]

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

Recheck some factors. Normally 4 Pits are enough. Dia 57mm x 3 m pipe must be considered.
