once if the increase and decrease is above pickup value. then i will operated on fixed time. if its decrease below the pickup current then the operating time will get reset
Can we say fault angle depends on where we place the CT in conducting line? Which means fault occur before CT is reverse and fault beyond CT and on the Conducting line is forward? What could be the standard angle variation for a fault in line side? Can I get some clarity sir
@@baranitech ok sir I thought so. I saw in some documents it depends on the load type. Ex. If the line is resistive load the angle set will be in approx 45deg. Also for inductive and capacitive load the angle recommended will be different. Can I get some note or documents on this.
Thank you for the knowledge sharing Sir.Excellent videos. Sir kindly share the testing procedure of motor protection relay like Micom 242, ABB REM 615, SEL 710.
You are the best bro
thank you bro
Excellent information sir, thnq very much
welcome
very well explained!!
thank you and welcome
Thank you
You're welcome
Thanks sir
welcome
But if fault current didn't stable or continuesly increase decrease so what will be happen.
once if the increase and decrease is above pickup value. then i will operated on fixed time. if its decrease below the pickup current then the operating time will get reset
@@baranitech thanks 😊

according to your ct connection is correct. and for fault angle is depends on impedance of the fault.

yours vector directions is anti clock(R-Y-B)but you put RCA vector in clock? is it OK
all should be in clock wise RYB( 0-240-120)

i will try to make for you.
Thank you Sir
Sir is it possible any real scenario that current pick up value is greater than psm though it is not in operating region.. When it is possible ??
it will not give trip
Explain how to use test block for relay testing sir
yes i will explain in future video
If we have a fault on phase R and Vr goes to zero can the relay to calculate the shift angle between Ir and Vr?
this case self polarization is very difficult to operated.
why did you consider RCA as 55 degree?
taken random
Sir in 7ut6331 relay how to read the base point 1 and 2 in that i read it is it fixed values please solve me sir
i also don't know but i will try to find
@@baranitech sir my mail iid is saimdvl2@gmail.com
If you have 7ut6331-6eb921ab0 settings file kindly once forward me sir
Sir please can you share the cross polarization method please
i will make soon
