நன்றி நண்பா. உங்கள் சேவை தொடரட்டும். தமிழில் அறிவியல் அருமை.
எளிதாக புரிந்து கொள்ளும் வகையில் அருமையான விளக்கம் நண்பா.
நன்றி.
தமிழ் பதிவுக்கு நன்றி நண்பா 🙏
தெளிவான விளக்கம் அருமை 💐
Thx for your knowledge sharing. I am an engineering design side and very useful to me understanding in aspects of practically how it's working . Keep Rocking.... I have a small doubut,For 64R (Restricted Earth fault Relay) one CT is connected to neutral side and another side Will required to connect in primary side (or) secondary side of transformer ? Same doubt in 51G(standby Earthfault really) also ?
அருமையான விளக்கம்
please continue your Tamil explanation,
hi bro & nice effort from you..
1. In all drawings of REF protection, all CTs shall be grounded towards protected equipment why?
2. In generally CT one side is grounded, please explain about CT current circulation with respect to grounding.
Thankyou
if ct is double earthed, current only circulated that earthing closed path..hence no current is flows through respective relay/meters
Keep it up sir....it's useful to beginners of relay testing
Thanks nanba

Neutral CT and bushing CT ratio different ah iruntha we move on low impedance method ( with leaner and non leaner resistor) bychance Neutral CT and bushing CT ratio same ah iruntha we move on high impedance method ( without leaner and non leaner resistor) just bypass the resistor...
Enaku therinjathu sonna... Thapa iruntha sorryyyyy nanba
Super nanba but enakku oru doudt air circuit breakera erth fault relay eppati operate pannuthu ,namma earth fautl relay remove pannuna acb work aaguma plz explain
yes unbuilt relay ETU unit moolama work agum
Sir please how calculate stabilizing resistor with explain one example
WHAT IS THE USE OF ICT in this circuit? i think primary & secondary ratio is same of the ICT.
Nice explanation
Hello sir s1 and s2 vanthu secondary terminals but neenga s1 primary and s2 secondary nu solluringa.... Koncham clear ra sollunga
You could ve tried to explain how to arrive at the ratio of the ICT for REF setup for the example of 200/1 NCT and 2000/1 Phase CTs.
Plz make it in english or hindi so that other state student will understand.
Thanks nanba..
Nice👍🎉👍
Plz make videos in English.. Then this will help you all ..
Sir explain. Star point in ct.and also explain single point earthing
I am the protection Engineer . please Tutiing with confidence . Kindly advice the interposing CT'S RATIO Selection.
It will be 0.1/1A ICT
Pls inform the Internal CT ratio
Power Transformer la act panura all relays aa pathi konjam define pani soli tharingla
Sure nanba..உங்கள் ஆதரவை நாடும் உங்கள் நண்பன்.
Differential Relay act for internal or external faults?
internal only
Super Bro
Can u explain about co balance CT ?
Video is available
@@Techdoct link plz
it is for earth fault protection...the resultant current of cbct flows to ELR
nice information ji
Sir please make videos in English language, so that we could understand,
hi sir please u put next video mmf emf difference use
ok bro
Sir plz need to Telugu element videos
Super sir
Thanks bro..

How to check instantaneous earth fault relay. Resistance model.
Very useful vide friend..👍
நண்பா நான் கேரளாவை சார்ந்தவன் . . உங்கள் விடியோவை அடிக்கடிப்பார்த்து வருகிறேன்.
உங்களுடைய போன் நம்பர் கிடைக்குமா?
Ref LA stabilizing resistor use panran gala athu ethukku
to neglect unwanted tripping and avoid tripping from ct saturation...(enak therinjuthu sonnen..if it is wrong,plz correct me)
Marshalling kiosk ynathu
Kindly tell it in English or hindi language. I'm unable to understand this tami/ telugu language
ICT means Interposing CT (Matching CT)
Which is this language?
Tamil
Anna na testing feeld la join panniruga but yanagu onnum theriyal basic relay an ct pt basic vedio sollunga na what up number send give me anna
Why both end supply in DC supply

What this for better understanding th-cam.com/video/q_CxKvyjgO8/w-d-xo.html
Pls upload vcb function

It will be 10/1A ICT
Ngr ??
bro....listen this...th-cam.com/video/mCWwzvP7RuU/w-d-xo.html
Neutral grounding resistor ... which is used reducing ground fault current of the transformer
define emf mmf
Explain in English also
I can't understand in telegu,
Hindi main video upload kariye sir
Please in English language
Soon I Update The Video
Pls describe in English
Mack a Hindi video
What you are talking about
Avoid using namba and learn first totally wrong concept
Thanks for commenting nanba...Do you know one thing i have installed, tested and commissioned almost 3 number of REF relay with stabilizing resistor..ok simply do not say learn.. if i am wrong tell the mistake that is good conversation... do not compare my channel with the text book..practical electrical never matches with your the text book.. if you are in power plant of above 32MW go and see the GCP drawing, there you will get the answer bro. i am telling that, what i have done in my experience. Many people do not know that using of interposing CT. that is doing main duty for High Voltage Power plant
Techdoct m a relay testing engineer in last 7 yrs
any how welcome.. do not underestimate anyone...
Techdoct m not tell you that your wrong try to improve about the basic bcos there may be a chance to feed a wrong information
@@kilaiyaraja5018 enna ma nenga...tell me mistake first bro...if I am wrong I 100% delete my video...nanba see ...I always tell my viewers to tell my mistake... Because everyone is not perfect. Even some thing that I do not know which you may know...healthy conversation is good for the engineer... in electromagnetic ref Relay without interposing ct for mismatched ct... Connecting the relay means you are absolutely wrong...if you have a time better read it..my source page... www.techdoct.com/electrical/restricted-earth-fault-protection-64r/
