CT Accuracy class : 0.2 vs 0.2S | Explained | TheElectricalGuy

In this video you will understand the difference between 0.2 & 0.2S accuracy class of current transformer. 0.2 & 0.2S are the metering CT accuracy class. This video explains the difference between the two as given in IEC Standard.

our videos are addictive! It's always a pleasure to watch them and to learn from you. Thank you for sharing!

This takes me back to my first job out of university designing HV metering and protection transformers at GEC. Designed dozens of these transformers and for something seemingly so simple they can be quite tricky to design especially the metering transformers. Used to have great fun testing them though seeing plasma building up around the primary when doing secondary over voltage tests on 400kV variants.

Excellent channel! I'm enjoying binge watching your videos. I'm a CS guy with an amateur interest in EE. Ty again. Very quality videos.

'S' stands for Special. The 0.2S class CTs guarantee the declared accuracy of +/- 0.2%, even with 20% loading.

Timings of your video are just amazing. I have thought in my head about this topic and notification pops up😂

Kindly make a video on traction sub station. And why they take only two phase supply amd also mentioned it's impact on grid. Coz the load is only on two phase not in theee phawe one phase load is totally zero.

Thank you a lot. I hope there's more video and playlist about electrical equipment for substation

Hi Gaurav, are you able to explain how to select the correct metering CT ratio

[L-ASHWAKMOHIDEENK]

hai
I have a dout
in this video the calculation in class 0.2 at 20% = 0.2*(20/100) = 0.04
but in this video 0.2 at 20 % = 0.2*(20/100)=0.35
kindly Explain with Calculation i am little bit Confused

[kantamaniteja]

S stands for special as per my knowledge Sir

[AchmadHanif-it]

Can we use class 0.2 ct to class 0.5 meter ?

[SUNIL_Kumar_]

What are the ratio error, composite error, phase angle error.... etc in CTs?
Can you please explain?

[a.r.vganeshraja]

In CT nomeculture P1, P2 what its meaning can u elaborate pls

[ravikumarnunna]

What Difference between 0.1 nd 0.2s ? Where this 0.1 is used ??

[chandrasekhar]

Pleaseclarify 0.2s class error- 0.25% or 0.2%.
