Transcripts
hello everyone and our goal today is to teach you how to use etab in five minutes
so we'll go ahead and we'll start off with a brand new project you also have the choice
obviously of opening up an existing project. In our brand new project you can essentially build
your diagram from scratch using the toolbars or you can simply go into the template and pick from
various pre-built reference designs that we have provided or you can add your own reference design
you can have entire MCC lineups or you can have complete substation uh configurations
as well as the engineering data or the reference design for the substations as well
you can also bring in wind farm collector systems and so on so forth so the sky's limit in terms of
bringing in a existing system so we can go ahead and bring in one of these
systems that we've already built uh as an option but if you're unhappy with it you can
simply delete it and start again uh when you delete something from etap it always goes to
recycle bin so you can always bring it back at any point in time or purge it one more time again
let's go ahead and build a quick model so we have our power grid our our bus we want to add a relay
so we can add a ct and a relay maybe a transformer perhaps a cable a bus and let's say we have two
motors in the system so with that i've quickly built my diagram and you can see that the
the program does its best to set up the diagram based on the spacing rules and we can go ahead
and now specify the missing information this is a 5 mba transformer and can simply bring in typical
impedance from ansi or iec standards and as far as the cable is concerned we can put in the length
of the cable and pick the cable from the library and of course there's also functions available to
size and derate the cable as needed the motor data is already there based on our default
data which you can always change but we are ready now to run our power flow calculation and you can
see the results directly on the diagram the units are turned on so you can essentially quickly
toggle between them or you can simply switch between different types of units in this case
kilowatt volts or percent for the voltage or you can also turn on and see the kva and the amps for
the network so our load flow is done let's go ahead and switch over to short circuit run the
computation and the program does a terrific job at letting you know that you're missing information
so you can double click on the error message it takes you the component that has the issue
and you can plug in the the data to complete your study we're running a fault analysis so i
would like to go ahead and fault this particular bus and run the calculation again and we can see
the fall contribution from the feeder as well as from the individual machines in the network
ready to do a tcc curve no problem very quick and easy you can simply go to the ct type in a
ct ratio go into the relay make sure we have an output specified look i forgot to add a breaker
not a problem so what we can do is quickly come in here add in a breaker no need to break connections
the program simply allows you to snap the breaker in line now we can go back to defining uh the
output for this relay which needs a digital output and it's going to be circuit breaker number two so
that's automatically interlocked for me and then from the library which is verified and validated
you can pick from all of these different vendors and pick your favorite vendor if you'd like from
here so we'll pick a schneider relay which is a micom and it sets up the relay based on its
functions ocr olr as well as distance functions so you can specify all those details we'll turn off
the instantaneous for the time being and set our curve to an iec curve so we can go ahead and now
select this entire diagram and go ahead and plot it into our tcc so we can see the the relay curve
we can see the cable damage curve the transformer damage curve and the motor curve if you're ready
to remove details from this you can simply press delete it doesn't affect the diagram but only
affects the tcc itself and here we can see our setting page is set for schneider p44 and if
you're ready to change the time dial you can just simply adjust the time dial up or down or change
the pickup for this particular relay and this automatically updates the database everywhere
ready to test this protection no problem just simply drag and drop the the short circuit arrow
once again the program is letting me know that i i picked a cable that is missing some information so
we'll go ahead and pick a different conductor and re-run our test again and we can see that this
relay picks up and trips the breaker in 283 milliseconds so very quickly you can also see
a sequence of operation directly on the diagram and with that we can switch over to arc flash
run our arc flash computation uh we need to select a bus where we want default so we can right click
and fault run our arc flash study the program gives a warning that the ppe requirements have
not been approved so it's it's essentially doing a safety check and then based on the current short
circuit results and the relay setting uh in in the network we can see what the arcing current is
as well as the arc flash energy so from here you're ready to go to the arc slash page
see more details uh or go inside the sequence of operation for uh arc flash and you can investigate
in in more detail what's going on inside this network who's tripping and at what stage and
once you're happy with that you can simply go inside the arc flash analyzer and from here you
also have the possibility of printing labels work permits data sheets and a whole lot more
so within uh five minutes we've shown you how easy it is to build a diagram and run the calculations
with an etab going all the way from load flow to short circuit to protection to arc flash thank you
you
