- DC Earth fault in DC control system is very usual which occurs in substation, power plant or anywhere in control circuit where DC supply is used for control purpose. Finding earth fault location is very difficult task so before getting started to check DC earth fault we must know the basics of DC system and practical practice to use multi meter or DC earth fault detector.
For Practical Understanding keep watching my videos !!

Thank you for your valuable lecture sir. We are also facing the same problem in our 220kv grid. Now I will try to rectify it.
Sir aapka video bahoot hi achha rhata hai aur banaiye video plz plz
Thanks Ji.
very Very Importance point for the High voltage Switch Gear
Sir iam diploma apprenticeship in pgcl and wait for next video
Good explain with fine way
Very good
Very nice explanation
Thank you very much , please post such practical videos
DEAR SIR , Let me introduce my self as a protection engineer ,working for Schneider electric. Sir I got from your video that how I can know whether it is a +ve or -ve DC earth fault. As DCDB provide DC voltage to all required ckt(i.e C&R panels, CB ckt.) . So how can I easily trace out that particular ckt. where the earth fault occur so that I can make my system normal?
Thanks Mr.Sumya ! I am happy that you learnt from my videos ! keep it up ! all the best for your technical enhancement ;)
Bhai koi vacancy hai kya
If you have answer plz share with me
Thank you sir

Dear its been great effort you made, we really appreciate your this effort.
Sir, Ac supply me bhi earth folt ko isi prakar ham jan sakate hain? Kya yahi process AC me bhi hota hai?
Thanks
Awesome way of practical
Very smart explanation
Thank you sir. After identify how to solve this earth fault. 1Q. What is float charging & Boost charging and for 10 KW dc motor what capacity of battery bank required? Please explain.
So in the case above are we further going to trace the positive earth fault identified or look for loose connection at the MCB for rectification please explain? (Enjoyed watching your video)

thank u sir.
sir power factor ko lekar bahut confusion h iske baare Me detail se bataiye plz.
u r superb sir
It's helpful for me thks...
Nice info
You are great Sir
Than you sir for this help
Nitesh sir mene apne ghr me mcb 63 amp ka lga rkha tha Havells ka ,or aaj rccb lgaya 40 amp ka Siemens ka, kyunki ghr ka load km h . Jese ki mcb pehle lgta h or uske baad me rccb thik vese connection jb kiye to rccb ekdum trip ho ja rha h jese hi me koi fan load ya refrigerator load on krta hu ...Lekin jb mcb. (63amp. D.P.) ko rccb k baad lgaya to rccb normal work kr rha h ...ab mujhe ye btaaye ki ye connection shi ese hi rehne de ya fir rccb(40amp.) mcb (63amp. D.P) k baad lgaye.
And Jo mcb single pole k lge h vo 10 amp or 16 amp k h lekin jb me wire daal k socket se short kia to mcb trip hi nhi hota blki socket burn hone lg gyi. Plz suggest me some good idea
Tq boss
helo brother kya hal hay ye pochna tha k ht volt kitni dori say noqsan karty hay matlab kitny volt par kitni dori say ap kam kar sakty plz reply kijey GA thanx
Sir Mujhe multimeter purchase karna h..Substation k battery PM k kiye to kaunsa Multimeter lena hai ?
Sir, suppose there is a damage to few 2volt cells of the battery bank of 110volt battery system of dc supply. Can i remove say six cells and add a 12volt lead acid battery available for home inverter from market and add in series as an emergency. Will it have any consequences?
Good video
Good potential value positive to earth ? Negetive to earth ?
sir one q.
what is panel waring
How to trace and rectify this ground fault?
accha hain
what is the procedure to solve the +ground fault? if u have any video plz give me the link
Please provide information regarding what voltage values will be obtained when there is no earth fault..
Bhai..substation me jitne b equipments hote h unki selection kse krte h??? oske upper koi video bna do..plxZzz bhai
Please explain why 50% potential found wrt. Ground in isolated dc control supply system
Sir please btaiye kya shut down liye bina hum particular section ko one by one isolate kr ke means uska ckt disconnect kr ke (DCDB se) dc leakage test kr skte h
SOP ke anusar to shutdown lena hi chahiye. Bina shutdown ka koi bhi allow nahi karega aisa karne ke liye.
Thank you bro
Sir thank you, sir ekk ratings ke bare me ekk video banao
Bhai cable Megger kaise karte hai ... Ek video us par bhi. Urgent chahiye tha
Ha kal upload karunga Megger ka video !
Sir please aap ek 415 V ac to 220 V dc battery charger per ek video banaiye
hello.sir.agar positive and negative dono me EF nahi hoto to dono k bich me kitana voltage show karega?...
Nice sir
Why 220 v dc supply half between ph to ground..? Please sir fundamental clear...?
sir batye to hame samjhe me aya
Nice dar
nice sir
Super sir
Sir please speech merger testing
Dear sr
Positive aur negative me 220 v dikhata hai lekin positive me earth se +110 v dikhata hai neg me -110v dikha hai aisa kyo kyo nhi +220 aur - 0 dikhata
Nitesh brother, can you please provide the video on protection scheme design which you explained earlier but now i can't find them. please
Good evening sir
Sir ager positive or negative dono me earth fault ho to?
Sir Us wire ground Kahan hua hai kese pata chalega I mean us mcb Ko kholenge ya kuch aur method hai
Sir mujhe ek bat samaj nahi aya wt r the advantage to ground the +ve , if the +ve shorted to the earth how can we getting the voltage.
We r switch one by one feeder dc supply .but it's fault in battery charger how to check fault sir.
Nice
Pls make one video on oil filtration of transformer
thanks sir
I want to know what about Telecom Systems where we need negative voltage where the positive is grounded in order to give negative voltage to the systems
Thank sir, I have question, At power house, DC system display fault: Battery Earth Fault, How do check faul? Thank you!
Watch this Video. I have uploaded today to answer your questions. th-cam.com/video/auwNwBGX744/w-d-xo.html
This is in English language. If you want to watch in Hindi then link is given in the description box of this video. Or search in my channel. Thanks.
In some cases either positive or negative is grounded . If positive is grounded then how can we detect earth fault between negative and earth?
Nice g
How do I test a transformer differential relay slope, high sets?
Please explain..
sir provide any source for understanding relay setting of Siemens ,abb ,and easun relay as well as motor protections
Sir Relay k barame Kuch video banaye
Hi jyoti, aap mere channel pe sabhi video ko dekh lo, usme jo achha lage aap dekh sakte ho. relay ke bare me bhi maine video banaya hai. usko dekho.

Can you please give me the value of capacitance of dc positive to Earth or negative to Earth (of your substation)
If there is a minor difference between positive - Earth and negative Earth voltage then DC is leakage anywhere or not.If leakage then how we find out at which point DC Leakage and we can short it.Plz explain..
You would have got some idea by watching this video. Concept is same only. However I will explain in a separate video about your concern. Thanks.
What if there was no ground fault? What will be the voltage then between positive and ground and also negative and ground?
Ab earth fault ko trace kaise karoge jabki cable to sab jagah ja rhi ho underground and through chanel or congested area .....that u know what I am asking...
Plss reply
Video me maine bataya hai na trace karne k liye. Alag alag circuit ko pahle identity karo ki kis me hai. Uske bad trace hoga scheme ke according.
How we get voltage reference to earth where battery is not grounded.you only get voltage from +ve to- ve value.
So you must describe the middile point earhing first.
How we find exect location of DC grounding
Sir can I connect Galvanometer with the dc Circuit to check dc leakage? So that if there is any leakage, Galvanometer must deflect.
Galvanometer work on AC ...If I am not wrong. ! 😊
How i find DC lekeage in grid station system
EARTH FAULT NI HOTA HAI TOH POSITIVE AND GND AND NEGETIVE AND GND K BICH KITNA HOTA HAI?HEALTHY CONDITION ME I MEAN
hello sir, if you could explain in English, its far better to understand for those who are language problem.
*Hi Karma ! Thanks for feedback but I used to make videos in both Language Hindi & English. You may check list of videos on my channel. I do understand this, My viewers are from Glob and basically it's technical so I make video in both language on same topic and upload at the same time. Thanks*
mere substation ke battery charger me earthlikage ka indications aa Gaya hai. kese find out karna padega sir?
Dear sir, I am from tamilnadu . So please explain english also . Open new english channel and give that link sir
th-cam.com/channels/B3y6-CYWtZEf5JYLND06oA.html
Go through this. You will get my english videos also. I make video in two language on same topic. And upload at the same time. Thats my old video. Thanks.
Thanks sir
