    Sir, please advise why we should only follow the minimum short circuit of the upstream utility grid while calculating the relay coordination.

    How to set the TCC curve for 3 auto reclosers connected in three parallel branches with the upstream substation protections.
    The second is how to avoid the miscoordination between downstream circuit breakers tripping with faults in the upstream system in etap .
    Also , is it helpful to activate more than one OC element for example OC1 is for OCT and ST and the other OC2 is to be IOC for the same feeder.

    Hi Very useful video Congratulation. I have two question. 1. why you choose the set at 115 % ?, and second: Why you choose operación time 0.35 second ?

    Sir I'm planning to take a whole training this coming nov. May I know how much usually is the amount of etap training? Based on the ff.topics
    1. AC system modeling & cable sizing 1 & 2
    2. Load flow study, evaluation, result analyzer review.
    3. 3-D data base
    4. Short circuit study and evaluation (ANSI & IEC)
    5.Protective Device sequence and operation
    6. Arc flash studies.
    Thank you

      @@CemilFurkanCal If you are updating a cable library, you need an actual cable vendor/manufacturer that is being used for your project. Normally cable manufacturers have their own cable catalogues wherein you can extract important data such as impedances of the cables.

    Good day sir, may tanong lang po ako. Bakit po ba nag miscoordinate ang mga relays yung nag fault kayo sa substation 1 na bus ehh tama naman po yong calculations. At saka ano po basis nyo sir sa pag adjust ng mga curves sa tcc para ma coordinate na ang mga relays? trial and error lang po ba ang pag aadjust para ma coordinate?

    • @juliussalutan8006
      @juliussalutan8006  2 ปีที่แล้ว +2

      It was a nice observation po. Sometimes in relay coordination, you need to try some trial and error approach by moving the curves directly from the TCC to perform the coordination. This is a reverse approach. Once the whole system is working, then accordingly, modify your calculation based on the new location of the curves and check the CTI (Coordination Time Interval) if still valid or not. What I have performed is not an exhaustive approach, probably that's the reason why. The transformer protection relay should consider also to verify the setting wherein the setting has to be above the inrush point and below the thermal damage point of the transformer. The latter I didn't show it on my calculation for simplicity of discussion. It just a mere presentation on how the coordination has to be performed. The exhaustive approach is being performed on my latest video Protection Relay Setting Calculation for Transformer which calculates the low set, high set and instantaneous settings.
