SIR CT voltage 5v And the CT Burden is 25va
Amazing explanation. Thank You sir for making such video.❤
Kitna value accepted hoga wrm k liye?
💯 marks for explanation
Glad you liked it
jab moving part nechy wala hay tho upar connection kion lagana hay
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
Intresting video bro ❤
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
👍

Sir yadi koi vaccum breaker pol ka resistance १००micro ohm aa kam karne ka upay bataye
Sir I have a question, kindly reply. Can we charge transformer, which kept idle from one year. Is there any chance of tripping. Transformer rating range above 2.5 mva 13.8kv/400v. BDV value of oil is 37KV.
If Transformer is not in service for 1 year, then we have to go for all routine testing of transformer.
Sir make a video on how to learn wiring diagram(scheme).for PSS all panels and equipments.
Sir pls make a video on FOTE panel and PLCC panel how to work this both panel and wiring connection.
Sub transient starting me hota hai baad me transient hota hai. Aapne galat btaya hai video me. Please check and verify
Very nicely explained Sir. Thanks a lot.🙏🙏
You're welcome 😊
Super👏👏👏
Thank you 😊
