Dear sir, First of all thanks for share such a useful information, I have some doubts: 1. Can we connect dc system earthing with AC system earthing if answer is no what is the reason, 2. How we know the fault current capacity can you please elaborate more 3. How we know th clearance time for fault level Regards
Thanks for educating us. After calculation (50×3.5 sqmm or 25×8 sqmm) conductor can be used for 20kA fault current. Question (what should be the length of cable or busbar ?)
Thanks for this important and useful information related to safety also. Pl make such more useful infomative vdo, One query comes,the given fomula does not depend on length of cable.For lower and higher length,the same formula be usefull....?
sir fault current how to find ? 1.As per main mccb in controll pannel 2.As per MCCB before Controll pannel 3.As per main power cable current carring capacity ? current carring capacity for copper is १.४ amp for per scmm then K vale how they related and time can we take like 0.१ sec
Sir star delta starter me delta contactor k liye alg se pt kyu lagate h kahi kahi mene ye dekha h or control k liye pt se adhiktar r or y phase hi kyu use karte h incoming k liye plss jawab jarur dijiyega
Yes good clearance pls help Ans regarding resistance of Earthing residential building substation small scale residential and what type of Earthing value select for different places thanks sur pls tell me regards Sunil Tripathi Mumbai
Sir reltion between cable size and clerence time for short circuit is contradition as directly propotional scure root of time totally puzzeled cleence time कम रखना हे ताे पतला cable डालना हे कुछ समझ मे नहि आया सर ये formula
I also use 300x300x 2 mm copper plate and 8/10 gauge copper wire conneted by 8 mm Brass nut bolts or sometime brazing at center and at one of corner for 200 amper capacity distribution or controll pannel
respected sir thank youuuuuuuu soooooooooo much . Because of you i am able to crack 3 interviews . sharing my interview question hope you will make videos on this topics.many question came from your vdo so i am not writing here again . >Can electric motors can be used as generators? >megger? >insulated bearing on motor ? >synchronization of genrator , protection ,all lamp method etc >shaft grounding ?
Many many congratulations Adarsh.. I am really happy that you get benefits from the video of this channel because that is one of the reason to start this channel. All the very best..👍

Nice video sir, keep posting knowledgeable videos...👍👍👍
Good evening sir nice topic
Nice information sir!
Good concept sir.thanks for helpful concept. Love From ❤️ PRAKASH ❤️
Nice information sir...
Thanks for educating us. After calculation (50×3.5 sqmm or 25×8 sqmm) conductor can be used for 20kA fault current. Question (what should be the length of cable or busbar ?)
Thanks for useful information.
For individual equipment how we will decide the earth conductor size.
Please provide video on earth mat also.
Thank you very much Sir. Will you please let us know for the sizing calculation of earthing wire for PLC Panel which have instrument earth only.
Good explanation sir, pls make a video on lux/lumens calculation with formula, its a humble request
Sir thank u for clear the funda of earthing conducter size
Very nice sir.
Very informative video sir, please make video on how to calculate fault current
Sir please make a video for new electrical engineers,how they will study electrical drawings.please sir
Get a drawing and study it.
Too good
Good.... Please share designing of transformers and dg sets also
Thanks for this important and useful information related to safety also.
Pl make such more useful infomative vdo,
One query comes,the given fomula does not depend on length of cable.For lower and higher length,the same formula be usefull....?
Wow thank you
Mr. Joshi will you make a video on tank and pipe Cathodic Protection.
Very nice video Sir.
Please industry me earthing banani hei us k liye video banaein.
Thanks
Please make a video on distance protection relay
Motor ki body earthing ke liye kitne hp ke liye kitne sqmm ka copper conductor used krna chahiye
Brilliant
Thank you..
Cleared sir .
Thank you...
Very nice Explain 🙏
System ka fault current Kaise nikalte he please explain
Ac wire use kare ya dc earthing me
molding CT(used in panel) how to so partial discharge test doing and its calibration doing..please upload video .
Thanks.
How to select a grounding cable for a portable DG
sir fault current how to find ?
1.As per main mccb in controll pannel
2.As per MCCB before Controll pannel
3.As per main power cable current carring capacity ?
current carring capacity for copper is १.४ amp for per scmm then K vale how they related and time can we take like 0.१ sec
What is the formula for converting mmsq of conductor to size of GI flat conductor??
Sir star delta starter me delta contactor k liye alg se pt kyu lagate h kahi kahi mene ye dekha h or control k liye pt se adhiktar r or y phase hi kyu use karte h incoming k liye plss jawab jarur dijiyega
Yes good clearance pls help
Ans regarding resistance of Earthing residential building substation small scale residential and what type of Earthing value select for different places thanks sur pls tell me regards Sunil Tripathi Mumbai

I have place copper plate for earthing ,in size 12 inch x 12 inch ,2 mm thick , so my question is this system can I place 14 kva of 3mc
I also use 300x300x 2 mm copper plate and 8/10 gauge copper wire conneted by 8 mm Brass nut bolts or sometime brazing at center and at one of corner for 200 amper capacity distribution or controll pannel
Sir pls make a video on dc drive parameters and it's wiring
Thanks 💐💐💐💐💐💐💐
Most welcome...
Sir please make a video on E. System fault and clearance time
Kitna clearance h aapke samjhane me apke charano me Mera pranam sir ji
Sir jo substation m jo road use hoti h 3mm ki
Sir here you said 180sqmm but how do you say GI flat size. Please explain
Pl. make a vedio how to check 24v DC shorting in cnc machine
Sir one more request,Pl provide a VDO related to calculation for how many earth electod is required in S/S or any Plant.
Dear Sir,
Leakage current 20 KA fix hota hai ya alag alag sytem pe depend karta hai ??
20KA is not leakage current. It is the fault level of system with a clearance time of 0.5 sec.
Aur ye value system pe depend karta hai.
Sir Ek baar

Sir bus bar rating calculation btaiye plllz
Make a video Sir
Still doubt has not cleared. Take an example of 30hp motor. Now tell that, what should be conductor size
Cable size caluclacution 3phase and 1phase
all motor installation ie rules ek br apke asaan bhasha me please samjhaiye
Last me Jo cable Ka Bataya vo samajme NY Aya sir,
Bc sidha sidha yeh kyo nahi kahta ki minimum 2 mm ki wire home earthing me lagani chahiye 😡
No clear
Jis mc ko video samajh me aayi hai Like thoko 😂
Earth pit pe ek vedio banaiye sir
