Welcome to the first part of the video tutorial on how to draw and define
networks in EcoStruxure Power Design - Ecodial.
In this demonstration, you will view the procedures to
Perform the worksheet arrangement, Draw a single line diagram
Define load power and polarity and Define system earthing arrangement
Lets begin by understanding how to arrange worksheets for a new project.
Worksheet arrangement helps you to arrange the multilevel networks or switchboards into different sheets.
This feature is very helpful to take network printouts in different views.
For your new project, you can use the Page Settings option to select the required paper size and orientation.
Select Paper Size option and select the required size of the worksheet for the diagram.
Select Paper Orientation option and select the required orientation of the worksheet for the diagram.
Enable the Show printing borders in diagram icon to display printing borders in the drawing area
while drawing the network.
Now you can start constructing the network and place the switchboards in the different worksheets.
It is possible to hide and unhide the links like this.
After hiding the links, references will be visible at the cable connection points.
Now the worksheet to draw the single line diagram has been completed.
Next, let’s view how to draw a single line diagram.
To draw the single line diagram, use the tool box or circuit library to select the different type of circuits.
To place an object, select it and place it on the worksheet.
Once you select the busbar, a double headed arrow will appear at the end of the busbar.
Hold the bar to click and drag it to the required length.
Use zoom tool icon or mouse wheel to zoom in or out the diagram.
Use the hand tool icon or click on the mouse wheel for the pan function
Select different circuits from the circuit library to draw and complete the network.
Now that we have drawn the single line diagram, let us learn how to define load power and polarity.
Select a circuit, as a whole or only a component, to display its properties on the right side.
Define the power load for the selected component by providing one of the inputs for kVA, kW, or A.
When the circuit is energized, you can see the circuit color change from blue to black for the load circuit.
Similarly, energize the other circuits.
This time we will change the kW value.
Next, we will change the A value.
Select the load polarity.
Identical load circuits can be represented by defining its number of circuits.
The power demand is automatically calculated for the upstream circuits up to the power source.
Change a load power.
When changing a load power anywhere in the network,
the upstream power demand is automatically updated and source is resized.
Our next step is to define the system earthing arrangement.
You can see the type of system earthing arrangement (SEA) at the MV-LV Transformer.
Here, the default system earthing arrangement is TN-S.
If you change the system earthing arrangement at the MV-LV transformer,
it will propagate the same to the entire network.
Can you have different system earthing arrangement for the same network? Let’s find out.
Here, the network is using TN-S earthing type.
Select a feeder circuit and change its type of system earthing to TN-C.
You get an error message that the selected earthing type is not compatible
with the upstream system earthing type. When you click Close, the earthing type remains unchanged.
You can view the system earthing arrangement type in the data table for the transformer.
If the network is using an LV-LV Isolation Transformer,
it is possible to have a different system earthing arrangement.
For instance, here we have an LV transformer with primary earthing type as TN-S
and secondary earthing type as TN-C.
Let’s change the earthing type for a load circuit to TN-C.
The change is accepted since the combination is compatible.
Now lets change the earthing type to TT, which is not compatible with the upstream earthing type of TN-C.
Here is the error message for non-compatibility of the earthing types. Click Close.
The earthing type remains unchanged.
Note that multiple earthing types is not applicable while selecting the LV-LV Auto Transformer.
This concludes the video on how to draw and define networks in EcoStruxure Power Design - Ecodial.
