hey everyone in this lesson we would

like to discuss how to do a simple

single line diagram in each program so

in order to do a single line diagram we

will use all of our elements inside here

for easy measurements and DC now first

step is that we can add our elements in

this white port or we can activate the

grid in order to see all of the lines or

align all of our elements so in order to

activate the grid you can see here this

small sample show grid lines so that you

can simply align all of your elements

easily inside a tab now what is the

first step first step we would like a

grid ok a power grid you'll see here we

have here a power great click on it one

click then go anywhere one click and go

anywhere for example here like this ok

now another thing I would like a

transmission line you will see here is

this one a transmission line click on it

then put it like this ok now we need a

transformer so if you go here you will

find here a 2 winding transformer click

and put it here for example another

thing we would like Lambeth load or a

cable cable at first if we go here you

will see this one impedance this one is

our cable click on it then put it for

example here ok then we need our load

for example we'll choose a long bit load

so the run bit load will have a sample

of this one ok one click and would it

anyway for example here now we have the

power grid providing power through

the transmission line then this

transmission line will go to a

transformer a step-down transformer for

example then giving this a cable coming

from the transformer to our loot okay

so we need to connect all of these

elements using passports so you'll see

here a pass one click and you can see

here for example like this so we have

only one bus okay we don't have any bus

you'll see the mouse only here but I

would like to add a pass power here

which is this one another one after the

transmission line which you connect this

between the transmission line ends a

transformer and honest up a spot here

another pass bar here so in order to do

this instead of just one click and doing

it every time we have a very simple

solution you can double click on the bus

power okay double click then go anywhere

for example here you will see that I

have now the past power ok again so I

can put it like this another one here

and so on now if I finished my using the

power you can click on the mouse ok now

we need to connect to the elements you

will see that here this is a power grid

when I come close to it it becomes a

paint color click on it and drag click

and drag in order to connect it anywhere

you'd like

I would like to connect it to passport

number one you will see that when I come

close to passport number one when I

select it you will see it becomes the

paint means it is connected to it so

leave the mouse they are connected to

each other take this one and drag and

connect take this one and drag to

connect take the transformer and connect

take this transformer ok we need to move

this click and drag in order to move the

world

okay click this one and put it here

click this one and move it here okay and

you can do another thing you can click

on the cable and for example move toward

the Z pass you'll see that it becomes

pink means they will connect then leave

the mouse so they are connected you can

select and drag like this and move it as

you would like okay

the Lambuth load like this okay so now

we have a power grid through a

transmission line power transformer then

underground the cable for example to our

load now if I would like to align all of

these elements together I will select

all of these elements then right click

then alignment then you can choose any

alignment form you would like as an

example I will choose this one okay this

a line you will see that here this one

sees a written word here or written

sentence here okay

alignment you will see that here it says

align selected elements in vertical at

the central location of the anchor

element they add the element which I

selected okay so if I click like this

you will see that now all of the

elements or send art together

okay now we would like to do another

sync if I would like to add another

cable and root okay or save this one as

a template in order to use it several

times so I can click like this and

select this two elements which is the

cable ends along bedload then you will

see that here there is upward here an

option called get done plet or add to

only V template one-line view template

add to one line view template like this

you will see that here it tells you to

save stemple

it as you would like for example I will

call it template number 2 ok and save ok

following a wall generator successively

add this extension ok now what is the

next step if I would like to add more

than one cable end lumbered load simply

go back get template ok and you see

template number two which is a cable and

long bed load then ok now we will find

here this is the element which we saved

before okay very nice so we can take

this and add it like this move it like

this select and move okay and we can do

a nice thing to zoom in like this ok

let's go down order to see all of our

elements ok so get the mouse now what is

the next step

now what if I deleted this element for

example delete this one ok you will find

that the template when I selected this

one all of the components are selected

together why because they are a template

now right click and click ungroup okay

so this element you can select it alone

or this element or even the passport so

for example if or how it deleted the

long blood like this click on delete now

if I would like to get it back you will

find it in here system dumpster click on

it you'll find here this is the one

which we deleted before okay

this load now you can control see then

get back to the online diagram and

control V now I got back the element

which I deleted

okay I copied it from that system

dumpster and returning it back here okay

now what if I have a very larger system

okay a very large system and I would

like to add it as a network

okay so network composite which is a

here composite network one click and

click anywhere so find its called

network number one okay okay now I would

like to connect it to this pass bar we

can click on this pass bar and extend it

like this okay click and drag for

example now I will connect it for

example to this point okay now if I

double click on the network you'll find

it is having a four point one point

connected to pass three they left the

point the right one and the bottom point

okay it has four points the upper the

lower the Aza bottom right and the left

you will find that the upper one is

connected to post number three let's get

back window and only v1 edit it okay if

we get back you'll see that here the

upper one is connected to post number

three exactly as it says inside the

network now we can double click the

network in order to add any line diagram

we would like another line diagram if it

is a very large system okay so we can

click on get template for example we'll

use this loot okay and we'll connect it

for example to the bottom one okay or

not the bottom one we will connect it to

the upper one like this okay so what

happens here okay let's move this so

what happens here is that this load is

connected to the upper point and the

upper point is connected to passport

number three so if we get back window or

le v1

you'll find that this point is connected

to the upper point of the network which

is connected to our loot okay so from

this you can add several elements inside

the network and connect it to this point

or this point or this point and getting

back to our Oh le V we can use this

point or this point of this point to

connect it to a different elements in

the power system so in this video we

learn it how to do a simple single line

diagram
