Sir good But as per knee point voltage recommend when we increase 10% voltage at last point then 1.5 times current increase eg if voltage 100 then current 50 mA And knee point 110 volt then current 75 mA It's as per my knowledge But u explain very good👍

Sir, what ever you understand is the theory of the knee point voltage, the design of the equipment is prepare with more safety margin and accuracy margine, so that the equipment couldn't fail in any test. there the results shows, are totaly prectical results. where the knee point is mentioned by manufacturer and we are testing the equipment to check the mentioned results are meets the actual test which is site "acceptance test"

Voltage transformer ka kya jarurat hai... Direct veriac se connection dene se kya saubidha hoga krupaya bataye
@Insighttecs
@Insighttecs 10 месяцев назад
you need 2000V for higher voltage CT. thanks for watching...

Why we connect vt rather than directly applie to ct through veriac

Here at VK current is 16.8mA instead of 60mA...what is this?
@muniraja5317

Thank you sir 👍 and Knee point test should be checked once how many days sir ?
@substationtestingandcommis3452
Knee point is done only during commissioning of CT, no need to do in routine testing.
@biswaranjanmohanty4730
@biswaranjanmohanty4730 7 месяцев назад
Sir at 950V current should 60mA but in the test you got 16.8mA. is it ok ?
@Insighttecs
@Insighttecs 7 месяцев назад
it is good.... as the knee point is more than 950V...
@abhishekpatel8038
@abhishekpatel8038 Год назад
Will the CT not saturate if we inject more than 950V on the secondary ?
@Insighttecs
@Insighttecs Год назад
generally not... if you test the ct for knee point.. then you will get the point of saturation.
