sir can u explain by video what happen if we use different class for overhead line..substation A using CT class X..but another remote end substation using CT class 5P20..what happen if fault occured..??
Hai bro, We are using both metering and protection CTs in series ( at same feeder). So at the Fault time, how the metering CT behaves ? Is it get saturated? Another doubt, what happens to metering CT if protection not operate during fault ..
Protection CT's are designed to have small error during fault condition ,so that they can be Correctly reproduce the fault current for satisfactory operation of protective relay ...
Sir. 1% x 10A = 0.1A. So if current is shown as 10A then current is between 9.9A and 10.1A
Sir...., neenga semmaiya class yedukareenga..., vaazhthukal
Thanks for the short and sweet presentation.
Still have a doubt in accuracy class for Protection and measuring CT's.
Share your doubt.....we will learn mutually...
Very useful thanks uploading 👍
Thank you...
Errors of ct விளக்கமாக ஒரு வீடியோ போடுங்க நண்பா👍👍👍👍
Will soon nanba...

Good class tq sir
Very useful video sir thank you
Thank you...
Sir please explain ( CT POLARITY AND IMPORTANT OF CT STAR POINT CONNECTING TRANSFORMER LINE PROTECTION)
Super explanation....
Thank you....
Sir, Please make video on Hindi/English language,Where everybody learn that.

The protective CT's should not saturate upto 20 to 50 times full load current
Super sir
Please tell me about "PS CORE" sir , what is the use of PS core ..?
PS class stand for special protection like REF and differential protection

0.2 error na 9.8A Or 10.2A thana varum.Neenga 9.98 or 10.02 nu solirukinga apo 0.02 error mathiri meaning varum.
Sir yapdi ratio va choose pandrathu
Based on requirements....
Thanks electrical drawing reading video pannunga
Will soon...
Please upload breaker CRM USES
After posting VCB video will plan for breaker testing like CRM,dielectric test....

Already we made a video for this topic...
Videos available in our playlist....
@@generalengineering1194 s I seen thanks a lot
@@generalengineering1194 bro one more doubt capacitor stage yapdi decided pandrathu
👍
And different between sensors and switches in tamil
inductive and capacitive proximity sensor videos are available in our playlist....
Basic difference between sensor and switch
Sensor-Non contact sensing device
Switch-Contact sensing device

Bro AVR PATHI SOLLUNGA
Will do soon nanba....
Waiting bro
0.5s class explain pls ?
Even below 1% of load, CT ratio error will not exceed 0.5%. 0.5S class CT will use for sensible metering circuits
10.1A r 9.9 A
20 percentage aaa 20 times aaaa sir
20 times...
