    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.

    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

    yours vector directions is anti clock(R-Y-B)but you put RCA vector in clock? is it OK

    • @baranitech1026
      @baranitech1026  3 ปีที่แล้ว

      all should be in clock wise RYB( 0-240-120)

    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

    • @baranitech1026
      @baranitech1026  3 ปีที่แล้ว

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

      @@baranitech1026 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.

    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 ??

    why did you consider RCA as 55 degree?

    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.
