Sir your vedios are really excellent and please keep it up and continued for same type of knowledgeable sharing please put alleast two vedios per day Please focas more on wiring side I.e control and relay pannel wiring of substation , relay protection philosophy and wiring etc please reply me
Vast n clear idea about CT so good sir... Sir pls make a video on CT secondary connection i.e star connection from CTMB to control pennal kese connect hota hey... Kon sa core kese use hua hey...
Because current in all three CTS are in same phase.. additive current is observed in neutral wire. If three phase CTs get current 120 degrees apart and equal magnitude, resultant current through neutral will be zero
Open chode gaye ct ke secondary coil me high potential appear nahi ho jayega...? Secondary coil me hamesha kuch current hona chahiye, counter mmf ke liye.. fir chahe wo kisi bhi tapping se li gayi ho. Per secondary coil, kisi na kisi tapping se ct secondary ko closed loop me rakhna hi hoga
We give lot of knowledge.thank you for knowledgeable vedeo.we utilities in oue fields
Excellant method of teaching
Very good. Thanks 🙏
Very nice video sir lp.upload video about testing of CT knee point
Sir you superbb .

I.e control and relay pannel wiring of substation , relay protection philosophy and wiring etc please reply me
K.. we will cover that soon
thanka sir
Thanks sir , you great
Thanks sir

Why we get 3 times current in neutral of that connection you showed?
Because current in all three CTS are in same phase.. additive current is observed in neutral wire. If three phase CTs get current 120 degrees apart and equal magnitude, resultant current through neutral will be zero
Sir agar feeder ki relay ka over current ki setting 250A hai to kya 250/1 ka CT use kar sakte hai
CT ratio rated current se kuch jyada hona chahiye.. plus accuracy class par bhi depend karta hai
@@beingelectrical6641 thanks sir
सर CT में अगर तीन secondary coil हो तोह क्या ct का एक coil को short कर बाकी दो coil को open किया जा सकता है,no load condition में
Open chode gaye ct ke secondary coil me high potential appear nahi ho jayega...?
Secondary coil me hamesha kuch current hona chahiye, counter mmf ke liye.. fir chahe wo kisi bhi tapping se li gayi ho.
Per secondary coil, kisi na kisi tapping se ct secondary ko closed loop me rakhna hi hoga
SIR.why pt secondary are not shorted. Sir please make vedeo on pt.thank you
Sir tell me a difference between P T CVT and CCVT
👍
Sir give a lecture of L/A
Sir at time chk S1 - S3, S2 and S4 will be opened
Yes.. only two terminals need to remain connected and choice of terminals is made based on ratio requirements
sr आगे का विडियो कब तक आएगा
Sorry for the gaps in videos..the sequence will be resumed shortly.
