We are pleased to announce the release of ETAP Power System Save hours of tedious hand calculations, manual excel manipulations, and take the. One Line Diagram is the method of representation of modeling the electrical system in ETAP for network analyses. ETAP supports the creation of unlimited. Abstract-Power is essentially required for the development of any country. To maintain the generation of electric power at adequate level the power has to be.

ETAP is the leader in power system analysis and management tools. The purpose of this tutorial is to introduce the Load Flow Analysis module, voltage using transformer LTCs and how ETAP flags overload conditions will be.
Various elements will be added to the one-line view OLV , and an introduction to composite networks will be made. If a Load Model needs to be entered. Doing so will open the property editor for Mtr2 as shown below. Ari Amrinal Putra. The ANSI methods are the default for short circuit studies.
The bus Arc Flash page allows you to get Arc Flash results instantly. You may also define the system grounding configuration of the equipment feeder.
If you know how long it will take the protective device to clear the arc. Go to the Arc Flash page and select the working distance. Select the User-Defined Arc Flash calculation by selecting the User-Defined radio button and you will get the incident energy. This distance is automatically populated based on the voltage level and type of equipment. You can change the default user-defined system grounding by selecting it from the dropdown list.
If you do not know the system grounding. A Crystal Reports viewer window will open with a label that is ready for printing..
Select the arc flash label template that you want and click on the Print button. For this you need to setup the global AF calculation.
This will save you a lot of time since you would be only required to define the type of equipment represented by each bus. The following image shows the recommended settings for a global AF calculation: The same input data is required if you use the quick incident energy calculator at the bus or if the global AF calculation is used. The next step requires the selection of the arc fault clearing time FCT.
If you do not select a TCC for the bus.
The IEEE method is a more accurate model and is set as default. In most cases. Once this information has been selected from the bus and Short Circuit Arc Fash pages.
The program will provide a full set of reports for all the faulted buses as well as all the labels for every protective device location and for the faulted buses. The remaining options to be selected can be left as default and are self explanatory.
It is recommended that you use the options shown in the AF Data page image since they allow the use of the latest standards with typical values. The Scenario and Study Wizards can be used to keep track and repeat the different calculations as shown in the images below where two different AF calculations were performed and recorded: At the same time labels. The AF Result Analyzer allows you to review results from several studies for comparison.
It will show the static and dynamic models that can be used to simulate real motor characteristics. On the Event page. The output plots will now graph the results of the study from time 0 to 10 seconds. From here you can add and modify conditions for your study. The minimum amount of data necessary to run each type of study will be entered. You can start or switch off individual loads or categorized motor groups with the Action by Load and Action by Starting Category features.
You can add an event by selecting the Event page and clicking on the Add button under the Events heading. The data you have just seen and changed is the minimum necessary to run a simple Static Motor Starting study. Once the calculation has completed. Click OK the save the changes you made in the study case editor. Actions occurring at each event time can be added. You can also change the operating load by clicking the Load Transitioning option to change from one loading category to another.
Click OK to save and exit. In the Acceleration Time Static Starting fields. Now you can add an unlimited number of events to simulate switching actions in a single Motor Starting simulation. Ensure that a Load Model is entered for this motor.
Under the Dynamic Model heading. Clicking on the Typical Data button will fill the necessary fields based on the ratings specified under the Nameplate page. Now go to the Load Model page to view the load model. If a Load Model needs to be entered.
Double-click the Syn1 element graphic to open its editor. The Motor Starting Plot Selection window will appear to allow you to choose which plots will be displayed.
Now you can run a Dynamic Motor Starting study. To view the plots that are generated as a result of a study. Select the plots you wish to view. The motor WR2 will automatically be updated.
Connecting a panel to a bus is the same as with any other one-line element. Open the composite network Sub3 Net by doubleclicking on it. The default connection pin of each panel is the top connector. It will be shown how to connect panels to buses and to other panels.
Note how Panel1 is connected. Note that you cannot add new panels in this demo. If you want to connect a slot to an external element. The Summary page of the Panel Schedule editor details the total loading on the panel. On the Rating page. On the Info page.
Double-click Panel1 to open the Panel editor. Note connections 2 and 8 are designated external in the figure below. On the Schedule page. Go to the Schedule page of the editor and set the number of poles for circuit 7 to 3 and Link type to Ext This allows a 3-phase load. Now you can connect the second panel to first by connecting the top pin of the second panel toExt-2 of the first panel as shown in the figure below.
Check the box entitled Calc Panel Systems. In order to connect the panels together open the editor for the panel connected to MCC1. Note the power flows to and from the panels. It will cover how to create a new Star View and how to add a new device to an existing Star View.
This will display the Library Quick pick. Click the Overcurrent Relay button presentation. Set the relay as shown in the figure. To learn more about relay settings. Relay dialog box.
Double-click the Overcurrent Relay element to open the Relay editor. To generate the Star View. Keep Star1 open for the next section of the tutorial. This will show more infromation related to the relay settings in the label tag. Enter primary and secondary ratings for Phase CT Click the Input page. Star Views for other protective devices can be generated in a similar manner. From the Mode toolbar. Right click on the label tag associated with the curve and check the Settings options.
Double-click the fuse symbol to open the Fuse editor. Element or group of elements on the one-line-diagram can be appended to one or more Star views in a similar manner. Switch to Star Mode using the Mode toolbar. Star1 view opens with the Fuse1 curve added. The color of each TCC curve can be assigned by pressing the Plot Options button on the right hand toolbar.
