Summary of ETAP capabilities from load flow to arc flash in five minutes
Transcripts
hello everyone and our goal today is toĀ teach you how to use etab in five minutesĀ Ā
so we'll go ahead and we'll start off withĀ a brand new project you also have the choiceĀ Ā
obviously of opening up an existing project. InĀ our brand new project you can essentially buildĀ Ā
your diagram from scratch using the toolbars orĀ you can simply go into the template and pick fromĀ Ā
various pre-built reference designs that we haveĀ provided or you can add your own reference designĀ Ā
you can have entire MCC lineups or you canĀ have complete substation uh configurationsĀ Ā
as well as the engineering data or theĀ reference design for the substations as wellĀ Ā
you can also bring in wind farm collector systemsĀ and so on so forth so the sky's limit in terms ofĀ Ā
bringing in a existing system so weĀ can go ahead and bring in one of theseĀ Ā
systems that we've already built uh as anĀ option but if you're unhappy with it you canĀ Ā
simply delete it and start again uh when youĀ delete something from etap it always goes toĀ Ā
recycle bin so you can always bring it back atĀ any point in time or purge it one more time againĀ Ā
let's go ahead and build a quick model so we haveĀ our power grid our our bus we want to add a relayĀ Ā
so we can add a ct and a relay maybe a transformerĀ perhaps a cable a bus and let's say we have twoĀ Ā
motors in the system so with that i've quicklyĀ built my diagram and you can see that theĀ Ā
the program does its best to set up the diagramĀ based on the spacing rules and we can go aheadĀ Ā
and now specify the missing information this is aĀ 5 mba transformer and can simply bring in typicalĀ Ā
impedance from ansi or iec standards and as farĀ as the cable is concerned we can put in the lengthĀ Ā
of the cable and pick the cable from the libraryĀ and of course there's also functions available toĀ Ā
size and derate the cable as needed the motorĀ data is already there based on our defaultĀ Ā
data which you can always change but we are readyĀ now to run our power flow calculation and you canĀ Ā
see the results directly on the diagram the unitsĀ are turned on so you can essentially quicklyĀ Ā
toggle between them or you can simply switchĀ between different types of units in this caseĀ Ā
kilowatt volts or percent for the voltage or youĀ can also turn on and see the kva and the amps forĀ Ā
the network so our load flow is done let's goĀ ahead and switch over to short circuit run theĀ Ā
computation and the program does a terrific job atĀ letting you know that you're missing informationĀ Ā
so you can double click on the error messageĀ it takes you the component that has the issueĀ Ā
and you can plug in the the data to completeĀ your study we're running a fault analysis so iĀ Ā
would like to go ahead and fault this particularĀ bus and run the calculation again and we can seeĀ Ā
the fall contribution from the feeder as wellĀ as from the individual machines in the networkĀ Ā
ready to do a tcc curve no problem very quickĀ and easy you can simply go to the ct type in aĀ Ā
ct ratio go into the relay make sure we have anĀ output specified look i forgot to add a breakerĀ Ā
not a problem so what we can do is quickly come inĀ here add in a breaker no need to break connectionsĀ Ā
the program simply allows you to snap the breakerĀ in line now we can go back to defining uh theĀ Ā
output for this relay which needs a digital outputĀ and it's going to be circuit breaker number two soĀ Ā
that's automatically interlocked for me and thenĀ from the library which is verified and validatedĀ Ā
you can pick from all of these different vendorsĀ and pick your favorite vendor if you'd like fromĀ Ā
here so we'll pick a schneider relay which isĀ a micom and it sets up the relay based on itsĀ Ā
functions ocr olr as well as distance functions soĀ you can specify all those details we'll turn offĀ Ā
the instantaneous for the time being and set ourĀ curve to an iec curve so we can go ahead and nowĀ Ā
select this entire diagram and go ahead and plotĀ it into our tcc so we can see the the relay curveĀ Ā
we can see the cable damage curve the transformerĀ damage curve and the motor curve if you're readyĀ Ā
to remove details from this you can simply pressĀ delete it doesn't affect the diagram but onlyĀ Ā
affects the tcc itself and here we can see ourĀ setting page is set for schneider p44 and ifĀ Ā
you're ready to change the time dial you can justĀ simply adjust the time dial up or down or changeĀ Ā
the pickup for this particular relay and thisĀ automatically updates the database everywhereĀ Ā
ready to test this protection no problem justĀ simply drag and drop the the short circuit arrowĀ Ā
once again the program is letting me know that i iĀ picked a cable that is missing some information soĀ Ā
we'll go ahead and pick a different conductor andĀ re-run our test again and we can see that thisĀ Ā
relay picks up and trips the breaker in 283Ā milliseconds so very quickly you can also seeĀ Ā
a sequence of operation directly on the diagramĀ and with that we can switch over to arc flashĀ Ā
run our arc flash computation uh we need to selectĀ a bus where we want default so we can right clickĀ Ā
and fault run our arc flash study the programĀ gives a warning that the ppe requirements haveĀ Ā
not been approved so it's it's essentially doingĀ a safety check and then based on the current shortĀ Ā
circuit results and the relay setting uh in inĀ the network we can see what the arcing current isĀ Ā
as well as the arc flash energy so from hereĀ you're ready to go to the arc slash pageĀ Ā
see more details uh or go inside the sequence ofĀ operation for uh arc flash and you can investigateĀ Ā
in in more detail what's going on inside thisĀ network who's tripping and at what stage andĀ Ā
once you're happy with that you can simply goĀ inside the arc flash analyzer and from here youĀ Ā
also have the possibility of printing labelsĀ work permits data sheets and a whole lot moreĀ Ā
so within uh five minutes we've shown you how easyĀ it is to build a diagram and run the calculationsĀ Ā
with an etab going all the way from load flow toĀ short circuit to protection to arc flash thank you
you
