Sir if heavy fault condition protection core can measure but metering core get saturated mean again we can use that core or we remove that ct....i never seen at any site..after fault condition...we r re charge the line...all ct core are working..it means fault current never cross the isf limit..
The CT core get saturated in fault current,then after it come back normal operation in normal current. The metering CT should be saturated at fault condition.because to safe the instruments
Not more applicable for MCT , because very small range of current rating(1.2 to 1.5 time of rated current) It applicable in PS CT , because it exposed to fault current of 20 to 30 time of rated current.
Point to point explanation . Very few channels on TH-cam like this.
Thanks for making such videos.
good yar , very simpal very eassy sikhate ho anna .
Thanks for your comment.
Good i under stand
Thank you so much sir, very & concept clearing vide
U r video r such short and informative and much understanding
Much more good video ji
Very informative video sir
Very good. Thanks 🙏🙏🙏🙏
Very good information sir 👍👍
Well explained 🎉
Sir,pls relay setting ke baremein pls aur video send kijiye
Pl clarify how 27v became the Knee point voltage, whereas you calculated 220v as the Kv, thanks a lot
Very informative video
Sir please short video on SFRA test that will be very useful to all viewers.
I will publish shortly

thank you sir
Thanks sir u have accepted by request.
How to calculate fault current if not given??
Can you explain?

Thanks sir
Sir what is BIL of CT kindly explain
Sir please explain,
How to calculate any system fault currents?
Thanks for your comments, fault current calculation video already published in our chennal.please check.
Why don't we give knee point voltage for Protection type CT's like 5P20 n etc.
Sir multimeter se cheack nahi kar sakte hai kya
The ohms will be in milli ohms,so the multimeter can not show accurately.
@@ElectricalandElectronictech ok sir
Can you explain in detail how the current is increasing by 50%?
50% current increased depend upon core property.
The core made depending upon core saturation limit
Sir transformer ke sfra test ke bare me bataye aur iske graph ko kaise analysis karte hai.thanks
I will publish shortly
sir ji i have a small request micom relay k basic uppor ek video baniye please sir
Please click the link 👇,to watch micom relay setting.

Sir what is the K
why Knee point voltage consider for PS class CT; Not for MCT?
Not more applicable for MCT , because very small range of current rating(1.2 to 1.5 time of rated current)
It applicable in PS CT , because it exposed to fault current of 20 to 30 time of rated current.
@@ElectricalandElectronictech Thank You,But fault current can flow MCT of secondary as well ,How it can manage this current?

K=2???
How
k=2 how
