[@karthickvelmani4126]

Perfect explanation. You taught same as my L&T trainer taught us. We want more videos like this sir. I am an Electrical Design engineer who working in switchgear field

[@ivanmeroni7714]

Thanks for the clear explanation. What will happen if in a CT with one primary and three secondaries, one of the secondary is open? What will happen to other two secondaries?

[@ak-vx1wt]

Thank you very much sir.
Your lectures are best

[@venkatesanvijaya5104]

Sir,
I am testing engineer working in switch gear field , excellent session sir.

[@kaushik_rebel]

Why use DC for de-energizing and not AC?

[@syerragaming8661]

sir if dc is applied to primary then there is a chance for huge currents in primary winding...then how it is justified sir in this situation...

[@patakotisrinivas1918]

Nice explanation sir...thanks a lot..

[@sumitlal7652]

Sir if current in the secondary coil is zero, so there will be no eddy current. So can we say that there will be a eddy current loss?

[@mdhussain363]

Keep providing such quality videos, sir, I have learned a lot from you, Thank You so much 😇💓

[@marcusgarvey9252]

How can I he-magnetized my transformer core?

[@er.pradhansingh1261]

Sir here sec current is not depending upon ammeter resistance. So can we say that if we use ammeter of high internal resistance comparatively, then ammeter will read same value?

[@ajayyadav-xq7yv]

I have seen one secondary terminal (S1) of CBCT kept open, on asking it was found not in line. Module was in running condition. My question how it is safe and different from CT

[@falconhawker]

good explanation : because the dependence upon the iron core hysteresis curve is emphasized

[@surendrakverma555]

Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏

[@happysingh-gk2dj]

Thanks a lot sir , I am student of IIT Delhi currently working in state electricity dept ,I want to design numerical Overcurrent relay for substation but not getting schematic or standard design , plz guide regarding above .thankyou ji

[@NguyenAnh-si2mt]

why the flux equal to current divided by resistance sir?
In my knowledge, the flux = current x resistance
Does the IL= Is-Ir?
Hope you reply soon

[@er.pradhansingh1261]

Flux = mmf/Reluctance

[@creazeworld1765]

Pl .upload a video about distance relay with numerical example .

[@vamsimouli9640]

Sir errors kosam cheppaledhu...play list lo unnnadha

[@mayureshapte9573]

It is possible that CT will blast in EHV system

[@TheTastefulTrekkerA]

Thank you sir 👍

[@reshabdasrajak47]

Sir CT's are Step Up or Step Down Transformers?

[@rolex8606]

Ct is step up transformer

[@saikrishnachintoju7495]

Tq

[@vinodhkumarnetheti6934]

Sir pls explain slowly pls🙏

[@30mAkills]

Without demo this is useless.
