How to check & find Earth fault in DC System | Substation | Power plant

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.

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?

[@NiteshKumarElectrical]

Thanks Mr.Sumya ! I am happy that you learnt from my videos ! keep it up ! all the best for your technical enhancement ;)

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.

[@umeshsarma53]

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

[@sharadtiwari755]

Sir Mujhe multimeter purchase karna h..Substation k battery PM k kiye to kaunsa Multimeter lena hai ?

[@erajay2010]

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

[@NiteshKumarElectrical]

SOP ke anusar to shutdown lena hi chahiye. Bina shutdown ka koi bhi allow nahi karega aisa karne ke liye.

[@ShubhamYadav-mu6go]

thank u sir. sir power factor ko lekar bahut confusion h iske baare Me detail se bataiye plz.

[@asifkhokhar9331]

[@uddipansarkar90]

Nitesh ji agar earth fault nahi hota toh +ve to gnd and -ve to gnd kitna voltage ana chahiye tha??

[@raytech6049]

We do service all these digital meters in Kolkata with best accuracy 👌 .

[@bartamo3766]

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?

[@sumittiwari327]

Sir kya multimeter se DB panel ki earthing check Kar Sakte hai? Uspar ek vedio bna dijiye

[@khan_tanzeem0521]

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)

[@Devendrakumarpankaj]

Thanks

[@DevD1111]

Hello sir- very informative video. Ek acchi grounding k liye neutral and ground k bich m kitna voltage hona chaiye.

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.

[@kalyankings2218]

Tq boss

[@ersachinsaini2064]

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

[@NiteshKumarElectrical]

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.

[@iswarmahanta6905]

Why 220 v dc supply half between ph to ground..? Please sir fundamental clear...?

[@asthalalakimasti1989]

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

[@aurobindamohapatra2768]

Sir thank you, sir ekk ratings ke bare me ekk video banao

[@ajayrai129]

Please provide information regarding what voltage values will be obtained when there is no earth fault..

[@adithihomeplant3661]

We r switch one by one feeder dc supply .but it's fault in battery charger how to check fault sir.

[@alienvaigyanik5470]

Sunder

[@harishaharisha3707]

Sir please speech merger testing

[@dinabandhukhuntia9077]

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.

[@VIKRAMSINGH-eo1lo]

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..

[@NiteshKumarElectrical]

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.

[@ZahidHussain-wk1zl]

How do I test a transformer differential relay slope, high sets? Please explain..

Sir... How to check yard light system in 66/11KV sub station is properly earthed or not

[@NiteshKumarElectrical]

1. Light - Check all the concerned ckt. 2. Earthing :- You need to test Earth resistance of earth pit using ERT meter. If value is ok then earthling is good.

[@anoopverma3912]

Nice sir

[@sagartrivedi7168]

Sir ager positive or negative dono me earth fault ho to?

[@manojshukla3598]

sir provide any source for understanding relay setting of Siemens ,abb ,and easun relay as well as motor protections

[@technicalexperience2785]

accha hain

[@erajay2010]

Sir can I connect Galvanometer with the dc Circuit to check dc leakage? So that if there is any leakage, Galvanometer must deflect.

[@NiteshKumarElectrical]

Galvanometer work on AC ...If I am not wrong. ! 😊

hello sir, if you could explain in English, its far better to understand for those who are language problem.

[@NiteshKumarElectrical]

*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*

EARTH FAULT NI HOTA HAI TOH POSITIVE AND GND AND NEGETIVE AND GND K BICH KITNA HOTA HAI?HEALTHY CONDITION ME I MEAN

[@aamirawan7998]

What if there was no ground fault? What will be the voltage then between positive and ground and also negative and ground?

[@sadaqatali9166]

How we find exect location of DC grounding

[@csgupta7017]

In some cases either positive or negative is grounded . If positive is grounded then how can we detect earth fault between negative and earth?

[@er.pratiksingh8339]

Sir please reply karna Mera job laga hi Estimation engineer me join krna chaiye kya FUTURE kaisa rahega Company panel manufacturing company hi please reply
