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. Regards
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?
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.
Sir plz make video on short circuit calculation by manually method regarding line to line and line to earth in transformers and Generator with solid grounded and impedance , thanks🙏
Thanks for this informative video. Just want to ask where have you downloaded your ETAP app? pwede po ba makahingi ng installer or ng link? Thanks in Advance Sir. God Bless
@@juliussalutan8006 sir good evening po, napa useful ng ginawa nyong on line ETAP tutorial. Malaking tulong ito sa katuald kong gusto matuto. Medyo mahal din kasi payment sa mga online class . Sir pwede din po ba makahingi ng installer ng ETAP software or link po . Thanks and mabuhay po kayo sir
Really great video buddy good effort, thanks alot
one of the best overall lesson
Thank you so much. So Helpful and informative
Sir, please advise why we should only follow the minimum short circuit of the upstream utility grid while calculating the relay coordination.
Good job for your valuable information but please have a look to the vedeo quality as contents are visually not clear in this vedeo

sir, mayng adlaw. Lawrence bordallo ni.
Superb!!!!
what are cable lengths?
THANK YOU SIR! I HOPE YOU EXPLAIN HOW TO READ THE TCC VIEW! LIKE I DONT REALLY GET WHERE TO START READING VALUES. THANKS AGAIN!
After short-circuit calculations, which short-circuit current will we use for instantaneous overcurrent (50) values?
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 ?
can i use ct ratio of divisible by 5 rather than 1?
Hello, there are 4-5 different options in the Pickup range tab. I don't understand how we make the selection.
??
what is length of cable
Sir, how do you determine the operating time? Thank you.
Thank you sir for this video..😃

HOW TO ADD A READY CABLE LIBRARY TO ETAP ?
Please refer to this tutorial video th-cam.com/video/T43cB-ODwv0/w-d-xo.html
@@juliussalutan8006 I know you told me but a lot of information is needed for the cable I want to add, how can I find them all?
