- Trip circuit supervision relay function ( TCS )
the following question are going to see in this video
1.What is Trip Circuit Supervision Relay?
2.Working Principle of TCS?
3.Application of TCS?
Dear Brother, thanks for making such a useful videos. If one has little bit experience can also be able to gain knowledge from you. In running plants or unit went for shutdown every one can't get access to protection system. In this channel you are sharing your knowledge and experience , thank once again for your efforts. Some of your subscribers may discourage due to lack of their experience in the relevant field/ language problem , pl don't bother.
We are enjoying your videos, pl go ahead.
thank you and welcome
You explanation is very simple and knowledgeable. Any body a bit electrical knowledge can learn.
Thanks and welcome
Thank you Sir for sharing great additional knowledge for me being working in the Oil Gas Refinery. God bless you more
thank you and most welcome
Thanks a lot. One of the best videos for Electrical Engineers.
your most welcome
Super bro keep going
Thank you so much
very well explained....to the point...
thank you
Very Nice Sir !! Really I learned about TCS Relay !! Thanks a lot !!
Excellent work 👍
thank you
Very good explanation sir..
Thanks and welcome
Nice video brother. Very helpful keep up the good work!!! Kudos!!
Thanks,
Thankyou sir it's helpful
Excellent explanation!! Can we get more videos about configuring and parameterizing relays?
Thanks, you are best teacher
So compact study. Thanks.
Welcome
Super Anna.... Ur explanation are really good
Good job sir
Thanks
Super anbu
thank you
Sir your explanation is very good.I have one request plz make series wise all video and explain in english. Thanks
Explained very nicely.
Please share video of LBB protection.

Superb 👍
welcome
Excellent explained
Thanks you so much Sir 🙏🙏
Nice, explanation sir,
Please make a video of generator protection.
Surely
Thank you
Useful momentz thankz alot do you have VAX31ZG0750BA model wiring diagram
welcome , i will check
👍👍👍
Can you explain AVR drawing of 300MW Alternator....
i will try to make
Tell us about numerical supervision relays, e.g. avana, jvs etc
yes i will make video
Dear bro how to avoid this mal alarm during closing and open because every time it will record fake alarm in scada
we have to make TCS blocking logic during open and closing time bro ..
Sir can we connect indication in series with pre close and post close circuit in series with Shunt trip coil, instead of tcs relay
What will be happen if the drop voltage which supplied the A& B coils became near the nominal voltage as the series resistances value became not stable or failed? Maybe tripping coil of c.b will operate. Or ? What will happen?
Also, I am facing the issue for transformer 33kv c.b was opening many times during load without any indication, is that has relation to TCS or not ? Plz advise
NO
If resistance failed i.e open circuit. isn't it? in that condition Tcs relay will not work.
Sir
In case of Preclosing condition,both A& B coil closing??
both coil will get pickup
Why are TCS Relay failure reason.
TCS relay indicator not glowing Green or Red.
MAY BE tcs Circuit DC path failure
If breaker trip continuously TCS showing healthy or not
What will happen if both A and B coils got failed....
It will also account as faulty trip coil .Is it right?
yes
@@baranitech1026 thank you
Brother are you giving training to the engineers through training center?
Relay trip coil ko kitni votage deti hai
approximately it will be 80% but you have to check Pickup and drop test to find this value.
Can u explain in 110v dc system how we getting 55v posetive to earth or negative to earth.(normally we ge 110v between + to- .then how geting 55v respect to earth)
How getting return path when any erth fault occure in 110v dc system
The DC battery system is to be kept ungrounded normally to avoid leakages. In battery charger, the mid point of the battery cell system is earthed via a high resistance.(Equivalent to not grounding the dc system). This will help you get the +55 V when you test betwen a positive point in the circuit and the earth. Likewise is the case with the -ve and earth. i.e, the return path is via the earthed high resistor.
Can you explain the Directional oc & ef relay
Check his channel.already he did
@@Mhdmnr68 thanks
Sir ,i have one question If we can do preclose connection in post close and vice versa what should be happen?
@@baranitech1026 Sir that's mean there is no effect on TCS indication and trip circuit working.
It will cause in TC burn out as the Post Close Supervision path will have a trip supply from the Master Trip relay in the event of a fault. So, after the breaker is opened, the Trip supply will directly come to the TC and it will remain there continuously causing TC burn out. Also, your post close and preclose TC healthy indication will not b available.
@@baranitech1026 & @kapil prasad
Coil "C" will pick up only when Trip coil open or DC supply fail only.
During intermittent time , that is CB open to close or open to close - Coil "C" will not pick up , because the coil "C" ( contact ) have inherent delay for Pick up. Hence no alarm will not come during transaction period .
@@baranitech1026
Coil C ( Contact) have inherent Pick up delay. Hence coil 'C" never pickup during CB operation transaction period. ( Open to Close or Viceversa)
It will pick only in Three conditions
1) DC supply fail
2) Trip coil open
3) Loose connection in Trip circuit .
Thanks Engr. Barani
Can share your Email ID
pre close and post close wire ko agar aap breaker end pe change karte hai to kuch problem nahi hoga agar aap TCS relay me change karte hai to TC coil burn ho jayega fault condition me breaker off hone ka baad usse hamesha +ve milte rahega.tc burn ho jayega.
Please could you zoom ?it's not clear, information
Hindi
Hindi language
i will try in future
English k chakkar me short circuit ho jayega sir hindi me bhi bna diya kro

Hindi walo ke liye specially
Hindi nahi aati ky aapako
भाई जी हिंदी में समझाओ
WHAT IS A & B PLEASE EXPLAIN FIRST COMPONENTS OF CIRCUIT FIRST BEFORE EXPLAINING THE CIRCUITRY. UP T 1.23 YOUR EXPLANATION WAS GOOD AFTER THAT YOU DID NOT TELL DETAILS "A" AND "B" AND ITS FUNCTION . VERY POOR EXPLANATION SIR . SORRY .
A Coil is for Post Close Supervision of Trip Coil. B Coil is for Pre Close Supervision of Trip Coil. If A coil or B coil picks up, the C coil will pick up.
