If fault in Q section Z1 towards R as you explained, then how not carrier send to P section relay to trip, what is scheme pls explain sir
No load current can be resolved into two components viz. 1. Component Iw (iron loss component) which supplies iron loss and very small copper loss Iw = Iocos(fy0) 2. Component Im (magnetising component) which produces mutual flux in core Im = Iosin(fy0). Thanks for explanation bhai keep uploading more videos related testing 🙏
🙏
bhai ya to English bol de ya to Hindi bol de chotyon ki tarha samja raha hai
Unused CT core should be short circuited not the terminals. If the other terminals of a used core remain open nothing will happen. Please rectify the concept.
Suppose the breaker stuck in 22kV substation where lbb is not provided then transformer LT associated with that feeder will get trip.
Yes
Nice explanation....
Thank you 😊
SIR CT voltage 5v And the CT Burden is 25va
Amazing explanation. Thank You sir for making such video.❤
Thank you 😊
Kitna value accepted hoga wrm k liye?
It depends on transformer specification and previous values
💯 marks for explanation
Glad you liked it
jab moving part nechy wala hay tho upar connection kion lagana hay
Both moving and Fixed Contact are in upper stack only
Nice explain sir
Keep watching
VAn=VAc+VNc VBb~VBc Vcb>VCc
Sir agar transformer ki winding agar short hai to kya resistance km hoga ya jayada
Voltage across secondary ct is 5v & burden is 25va. Kindly tell me this is right?
खतरनाक bade bhai aapne bahot hi achhe se samghaya aapka bahot bahot आभार....tahe dil se bade मिया 😊😊😊😊
Thanks
Fault hone ke bad trip hote hai
Rccb
Iec or ieee symbol
132/33KV??
Agar FAT test report nhi hai mai site Mai sfra test karke analysis kaise karenge without test report reference
Bro plz guide about Detanking of the transformer and strip down
Excellent bro plz send your email
I'm glad you found the video helpful!
Intresting video bro ❤
Thank you
Pls make video on ABB REF615 Numerical relay all current and voltage setting calculation and meaning of all settings??
Ok 👍
51 relay will not trip , why not trip
VAN=VAc+VcN VAC>VCc VBb~VBc
Thank you
Can you please share your contact number?
Local breaker backup protection (50BF)
Secondry voltage 5 V BURDEN -25 VA
Very good explanation Thanks
Thank you
Thank you for the detailed explanation, brother.
Thank you
Impedance is a constant parameter& free from voltage value and can not varry as per voltage variation
he is talking about the impedance seen by the relay. Relay calculates impedance based on V and I it is getting as input
Z=R+X as X always varies so it means Z can't b constant
Impedance of both side to be same
good sir
Thank you
Good job
Thank you
Very good.
Thank you
Very nice explanation bro
Thank you
Nice explanation
Thank you
Excellent Explanation
Thank you
Voltage- 5 V Burden- 25 VA
Nice
Thank you
Very nice explain sir👍👍
Thank you
Wrong apne jab LV ha HV ka test kiya then HV kiya so LV and ground ko short karna chahiye
For IR test, we can go for different combinations
Very good teaching
LBB protection
