What is Knee point Voltage of current transformer| knee point voltage Calculations &Testing in Tamil

#Kneepointvoltage

#Electrical
The knee point voltage defined as the voltage at which a 10% increase in applied voltage increases the magnetizing current by 50% for voltages greater than the knee point, the magnetizing current considerably even for small increments in voltage across the secondary terminals

Thank you sir.unga video explanation super sir🎉

[@MTBZSebastian]

Clearly explained 🎉

Lucidly explained. Thanks

Hi boss,
The fault current If mentioned in CT is 3kA.do we have to consider fault current of bus?

[@senthilkumar-ss5yq]

Sir suppose we found knee point voltage less than Ct name plate details mentioned voltage what action need to take? CT should replace.

Super sir thank you very much sir, 50,50n and 51,51n enna nu konjam nalla explain panni oru video podukal sir

Thank you brother
Keep support

[@jims9916]

what is the difference between VK and VK/2?

[@himachalambalu3279]

Formula mentioned in the video is it right....? kindly check.....
You have considered fault current as 4000A which is minimum ..... Even if you calculate fault current with trnsformer impednace minimum fault current would be 10kA or 15kA.... if you apply the same in the formulae then knee point voltage is very higher...
can you check and confirm....

During this test, should the CT make noise?
