Sir your videos is very helpful for Maintenance Engineers, keep on giving this type of Videos. Thank you Very much Sir

[@ashokmosun4204]

Good information 👍

[@MANOJKUMAR-qo8qp]

🙏 Thank you Sir ji 🙏

[@bikrammandal2582]

Thank you so much sir

Sir but Vk/2 ka matlab 475 volt me 60 mA current aana chaiye as per name plate??? Plz clarify

[@raghavmohan7599]

Super

[@subhamsaurabh9150]

Thanks sir , sabhi equipment ka sabhi test ka video banaiye jo kee erection commissioning me helpful ho

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👍

[@Insighttecs]

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"

[@naveenchaddha2802]

Sir please make a video for How to make/ disign/Calculat 200Amp - 400Amp Primary injection test set

[@subhamsaurabh9150]

Sir, substation ke earthing connection ka bhee video banaiye

[@pritampati7802]

Sir test k sath ager value kitna aaye according IEC ya pgcil rule k anusaran to acha hoga

[@schoolhalchal4975]

Voltage transformer ka kya jarurat hai... Direct veriac se connection dene se kya saubidha hoga krupaya bataye

[@Insighttecs]

you need 2000V for higher voltage CT. thanks for watching...

[@arunhazra1678]

Sir please discuss on cvt testing

[@skisrafil271]

Or wavetrep

[@babloofarkade9799]

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

[@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.

[@pemasquare8845]

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

[@biswaranjanmohanty4730]

Sir at 950V current should 60mA but in the test you got 16.8mA. is it ok ?

[@Insighttecs]

it is good.... as the knee point is more than 950V...

[@abhishekpatel8038]

Will the CT not saturate if we inject more than 950V on the secondary ?

[@Insighttecs]

generally not... if you test the ct for knee point.. then you will get the point of saturation.
