In addition, you can create your own alerts and enable them from the Alert field. In addition, there will be a brief look at study case editors and the Alert View function. Running a Short Circuit Analysis will generate an output report. If Prompt is selected then prior to running the Short Circuit Analysis you will be prompted to enter a report name.
This will open the Short Circuit Study Case editor, allowing you to change calculation criteria and options. From the Info page, choose a bus or multiple buses to be faulted. Sub 3 should now appear alone in the Fault category. Click OK when finished. Note: The faulted bus, Sub3, will be shown in dark red color on the oneline, indicating that it will be faulted. Helpful Tips You can also assign a bus to fault by right-clicking on a bus on the one-line and selecting Fault or Dont Fault.
If Prompt was selected as the output report in the Study Case toolbar, you will be prompted to enter a name for your output report. In addition, three studies according to the IEC set of standards can be performed.
Changing the settings in the short circuit Display Options can modify the results displayed and their format on the one-line. Note that breaker CB9 and CB18 are now colored magenta. This flag means that the device capabilities have been exceeded in some way. Also, click the Auto Display button and then click OK. Now run the same short circuit study again by following the procedure used above.
Note that once the calculation has been completed, the Alert View window will automatically open, as per the change made to the Alert page in the Short Circuit Study Case editor.
Notice that other protective device conditions appear in the Marginal Alert View. Note that the short circuit results do not change. The following steps show how to accomplish this: ETAP Arc Flash has typical equipment gap and X-factors built into the rating page of the bus.
You can take advantage of these typical values to perform a quick Arc Flash calculation. Open the editor for Bus1 and go to the rating page of the bus and select the type of equipment that is represented by that bus. This can be enclosed equipment such as MCC, switchgear, or open-air equipment, i.
Once you have selected the equipment type, select typical gap and boundary values by clicking on the Typical Data button. This will bring all the required gap and x-factor information as well as approach boundaries as defined by NFPA 70E. Go to the Arc Flash page and select the working distance.
This distance is automatically populated based on the voltage level and type of equipment. The working distance is defined as the distance from the persons torso and face to the energized equipment typically 18 inches for low voltage equipment. You may also define the system grounding configuration of the equipment feeder, i.
If you do not know the system grounding, assuming the system is ungrounded will yield conservative results default. You can change the default user-defined system grounding by selecting it from the dropdown list. ETAP can also be configured to automatically determine the system grounding. Select the arc flash label template that you want and click on the Print button.
A Crystal Reports viewer window will open with a label that is ready for printing. The bus Arc Flash page allows you to get Arc Flash results instantly. However, the bus calculator is simplified and it is not efficient when you need to run an analysis on hundreds of fault locations.
For this you need to setup the 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; however, in ETAP there are quicker and easier ways to define the input data required by the calculation. In this page you can globally define the equipments gaps between conductors, working distance, and other AF parameters to be used by 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.
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.
You can also right-click on the bus and select Fault or Dont Fault. The IEEE method is a more accurate model and is set as default. The next step requires the selection of the arc fault clearing time FCT. In most cases, the most conservative solution is reached by selecting a TCC only for the main feeder PD since they take a longer time to operate.
The remaining options to be selected can be left as default and are self explanatory.
For example, you can choose to update the global calculation results back to the Arc Flash page of the bus. Once this information has been selected from the bus and Short Circuit Arc Fash pages, all you need to do is to click on the Arc Flash icon on the Short Circuit toolbar to launch the calculation.
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 AF Result Analyzer allows you to review results from several studies for comparison, finding potential problems in the system with ease, and determining worst case conditions. At the same time labels, work permits, and data sheets can be generated and printed from here. It will show the static and dynamic models that can be used to simulate real motor characteristics.
The minimum amount of data necessary to run each type of study will be entered. From here you can add and modify conditions for your study. On the Event page, change the Total Simulation Time to 10 seconds.
The output plots will now graph the results of the study from time 0 to 10 seconds. Now you can add an unlimited number of events to simulate switching actions in a single Motor Starting simulation. You can start or switch off individual loads or categorized motor groups with the Action by Load and Action by Starting Category features, respectively.
You can also change the operating load by clicking the Load Transitioning option to change from one loading category to another.
You can add an event by selecting the Event page and clicking on the Add button under the Events heading. Actions occurring at each event time can be added, modified, or deleted by selecting the event and modifying the respective Action heading by Element, by Starting Category, by Load Transitioning. Click OK the save the changes you made in the study case editor. In the Acceleration Time Static Starting fields, enter 1 second as the no load acceleration time, and 3 seconds as the full load acceleration time.
