If the TNC Switch is stuck on C, then a continous pulse is given to the Breaker and if the Breaker Auxillary contact is sluggish, it will burn tge Closing Coil.
How can we ensure that closing coil gets positive before antupumping relay. Because if AP relay gets positive earlier than closing coil then it will open its NC contact that is in series with closing circuit and hence the closing coil won't get any positive and breaker won't charge. Therefore it is necessary to supply positive to AP relay via two parallel paths one having auxiliary NO contact and other having NO contact of AP relay. PS : The overall explanation is wonderful and very easy to understand. Looking forward to your other videos.
I think the reason to supply parallel path for AP relay is not exactly what you meant. The 52a in the path of the AP contactor is to make sure that the Close coil is not burned out if a user keeps the TNC switch to the Close position even after the CB is closed. Also, the NO contact of the AP contactor which is in series with the AP contactor ckt is for preventing another closing operation if it was closed onto a fault (SOTF condition).
As in your circuit service limit is in NC when DC main on 1st spring charge motor will oparete and spring charge done and the contact will open how the supply pass to coil. Please reply if I am wrong
Sir, Aap jo ye slide banaye h usko website pe upload kr dijiye please. And thank you sir for your affort to make us knowledgeable towards electrical wiring.
Sir, please send CT Connection video Two core or 3core CT 1s1, 1s2, 1s3, 1s4 My doubt is I take for metering 1s1 - 1s2 then remaining 1s3 and 1s4 what to do Please reply and also video
THANKS for the video. I have some confusion. The two diagrams you have shown for remote closing. You said that in the first diagram that there is danger to personal working on breaker if breaker is closed remotely. But when switch is at remote position how can the positive be extended to closing coil. If you observe carefully Both the diagrams are correct you have just interchanged the position of TNC and remote switch. At 15:45
In the first Diagram we have used Positive from the relay panel and so if the LR switch is faulty, the DC may get extended to the Breaker. But in the second Diagram , as we are using Breaker positive called as closing positive, when switch off the breaker DC, DC will not get extended.
Sir we are adding antipumping relay across cc and taking its nc contact to protect the breaker hunting effect.but how it is getting continuos supply to make its contact remain open till breaker is on condition.because we are giving only one pulse on that time 94 relay pickup and remain off.how sir
Once the CC is closed by the Close Pulse, the AP contactor will close its contact, whose NO contact is used in series with the AP contactor's coil. This will make sure that the AP contactor is kept in the energized condition until the TNC switch is released.
Dhanyavad sir, khup chhan prakare aapan samjun sangitale , asech video banvat raha .... dhnyavad

Very nice explain and informative video's keep it up.
Thank you
very very helpfull video....well explained....drawing is not seen properly
Thankyou very much sir.
Very good
Bhai thank you so much
Please explain OLTC control circuit if possible....
Thanks a lot bro
Thank you so much sir !
Sir 132 kv circuit breaker ka closing ka dragam ka video banaye sir
Very nice explain.please make same video for ACB
Sir if you can provide us with the acb bkr drawing, we will make a video.
Sir,if TNC Switch is stuck both side trip and close and bkr on remote position than closing problem occur ?
If the TNC Switch is stuck on C, then a continous pulse is given to the Breaker and if the Breaker Auxillary contact is sluggish, it will burn tge Closing Coil.
Thanks your dedication Amazing

Yes sir I have seen that in 220 kv breaker scheme. But not in 33 kv breaker.
Thanks for sharing with us though.

True
Nice
Please continue with such informative sessions
Nice video for us
As in your circuit service limit is in NC when DC main on 1st spring charge motor will oparete and spring charge done and the contact will open how the supply pass to coil.
Please reply if I am wrong
सर नमस्कार , 33 के वी CB और कंट्रोल पन्नेल का वायरिंग इंटर कनेक्सन कैसे बनाते है और इसमें क्या क्या ध्यान रखना पड़ता है
सर आपका बहुत बहुत धन्यवाद यह वीडियो मेरे लिए बहुत उपयोगी है
Good explanation sir.
Outstanding explanation with practical experience
Thanks a million 👍👍👌👌💐💐
Sir please added trip circuit control video
Sir we have a video on TCS please search in our channel
Very informative video 👌👌Sir...marshalling box to CR Panel, RTCC Panel wiring pe bhi video banaiye please.(40 mva xmer )
Great...waiting for trip circuit and spring charging circuit...
Before that you will get to see Troubleshooting Closing circuit problem
Sir your explanation is excellent thank-you sir
Very informative
Bhai pls 650 relay n.a. video banau
Great... i am waiting for ferrule like k5 ,k21 (what is the rule for ferrule)
Slowly you will learn them all
Good explain sir
excellent
Sir,
Aap jo ye slide banaye h usko website pe upload kr dijiye please.
And thank you sir for your affort to make us knowledgeable towards electrical wiring.
Sure Sir.
Nice explain
sir, electro- mechanical O/C and E/F relay par ak video banaye...
ok sir.
Sir, please send CT Connection video
Two core or 3core CT
1s1, 1s2, 1s3, 1s4
My doubt is
I take for metering 1s1 - 1s2 then remaining 1s3 and 1s4 what to do
Please reply and also video
If 1S1 and 1S2 are used, 1S3 and 1S4 are to be kept open as Circuit is already completed through the winding between 1S1 and 1S2.
Thanks sir
If, any axillary contact along with 1s1, 1s2, AX, 1s3
What we do auxiliary terminal
We use 1s1 and 1s2 for metering and 2s1and 2s2 for proction
Excellent ..

@@ELECTRICALFUNDAZ Thanks for the clarification 👍
Can you please explain TCH
Dear Sir, please watch this video on TCS/TCH th-cam.com/video/CYLK06GeDyM/w-d-xo.html

waiting for elecrical BAHUBALI part-3
Love this video..
Boss can I get all ansi code related circuit please give me
Your explanation needs little elaboration in detail, need to restrict current in TNC switch
yes sir we will
