systems, advanced time-current coordination and selectivity plots, geographic information system schematics (GIS), as well as three-dimensional ground grid systems (GGS).

System Toolbar:

The System toolbar is a convenient and efficient method of switching between ETAP systems.

System Views

Existing Views:If you are switching from Network Systems to Star Systems, ETAP will check for an existing Star View. If Star Views files do exist, ETAP will open the last accessed Star View and make it the active window.

New Views

If you are switching from Network Systems to Cable Pulling Systems and ETAP does not find any existing Cable Pulling Systems, it will then prompt you to create a new interface view for this system.

Project ViewETAP provides a special view of your project called the Project View. The Project View is a graphical tree representation that includes the presentations, configurations, study cases, libraries, and components associated with your project.

 Network SystemsETAP provides a graphical editor to construct your one-line diagram. You can graphically add, delete, move, or connect elements by using the one-line diagram Edit toolbar; zoom in or out; display grid on or off; change element size, orientation, symbol, or visibility; enter properties; set operating status; etc.

Mode Toolbar When you click the One-Line Diagram (Network Systems) button on the System toolbar, the Mode toolbar is available that contains all the study modules related to the one-line diagram.

In general, ETAP has three modes of operation under Network Systems; Edit, AC Study, and DC Study. The AC Study mode consists of analyses such as Load Flow, Short Circuit, Motor Acceleration, Transient Stability, and Protective Device Coordination.

Edit ModeEdit mode enables you to build your one-line diagram, change system connections, edit engineering properties, save your project, and generate schedule reports in Crystal Reports formats. You can select this mode by clicking the Edit button (graphically represented by a pencil). The Edit toolbars for AC Elements, DC Elements, and Instrumentation Elements will be displayed to the right side of the ETAP window.

This mode provides access to editing features that include:

Study ModeStudy modes enable you to create and modify study cases, perform system analysis, view alarm/alert conditions, and view output reports and plots. When a study mode is active (selected), the toolbar for the selected study is displayed on the right side of the ETAP window. By clicking the buttons on the study toolbar, you can run studies, transfer data, and change display options. The available study modes and associated study toolbars are shown in the table below.

STAR SystemsThe ETAP Star systems allow you to perform steady-state and dynamic device coordination, protection, and testing. Star systems utilize intelligent one-line diagrams, comprehensive device libraries, and an integrated three-dimensional database.STAR systems enable system engineers to efficiently perform protective device coordination studies. The intelligent features provide informed and reliable recommendations regarding the feasibility of the devices under consideration. This helps system engineers and planners quickly identify possible design issues and make informed decisions to improve system reliability, increase system stability, and realize cost savings.Underground Raceway System (UGS)ETAP provides graphical underground raceway systems (UGS). Each ETAP project supports multiple views of the underground raceway systems. Each view is a conceptual cross-section of desired raceways and heat sources that are in the same vicinity.

Ground Grid SystemThe safety of people who work and live around electric power installations is of paramount concern. The proper design of a grounding system is key to improving safety conditions and protecting the lives of all individuals who are in close proximity of electrical power systems. During unbalanced faults, the ground potential rise of a grounded structure presents a risk of electrocution to anyone who comes in contact with the grounded structure. ETAP provides a three-dimensional, fully graphical tool that allows for the

design of a ground grid system that adheres to IEEE or Finite Element Method (FEM) standards.Some of the design features of the Ground Grid Systems module include:  

Calculation of the safe step and touch potentials for any type of ground grid shape

Generation of three-dimensional graphic profiles and tabular results from the step and touch voltage values Optimization of the numbers of parallel ground conductors and rods Calculation of ground resistance and ground potential rise Calculation of cost of conductors and rods used Inclusion of soil type and configuration in calculations

Panel ScheduleETAP allows you to model the electrical panels used in electrical power systems directly on the one-line diagram. The number of panels that can be represented is unlimited, since ETAP supports the nesting of panels. Therefore, a panel can be connected to a sub-panel, and in turn, a sub-panel can be connected to yet another downstream panel elsewhere in the circuit. Each panel can be modeled as either a 3-phase or a single-phase panel. The 3-phase panels can be either 3-wire or 4-wire configurations, while single-phase panels can be 2-wire or 3-wire configurations. Internally, each panel

is comprised of protective devices and a collection of circuits that supply system loads.Cable Pulling

The accurate prediction of cable pulling force is essential for the design of underground cable systems. This knowledge makes it possible to avoid overly conservative design practices and to achieve substantial capital savings during construction.ETAP Cable Pulling Systems is used to determine the forward tension, reverse tensions, and sidewall pressures a cable is subjected to when pulled through conduits. The module can account for cables of different sizes and permits complex pulling path geometry. A point-by-point calculation method is performed at every conduit bend and pulls point. Both the forward and reverse pulling tensions are calculated for determining the preferred direction of pull.

Control SystemsETAP seamlessly integrates the analysis of power and control circuits within one electrical analysis program. The Control System Diagram (CSD) simulates the sequence-of-operation of control devices such as solenoids, relays, controlled contacts, multi-sequence contacts, and actuators including inrush conditions. CSD has the capability of determining pickup and dropout voltages, losses, and current flows at any time instance as well as overall marginal and critical alerts. A large library of equipment enables engineers to quickly model and simulate the action of relays associated with control interlocks after given time delays.

LibraryETAP provides the library structure for the following circuit elements: cable, cable fire protection (coating, stop, wrap), transmission line (ground wire, phase), control system devices (button, coil, contact, and solenoid), motor (nameplate, model, characteristic, and load), low voltage circuit breaker, high voltage circuit breaker, fuse, relay, trip devices (electro-mechanical, motor circuit protector, solid state, thermal magnetic), overload heater, harmonic sources, load interruption cost, device reliability, and battery. The ETAP library file is named ETAPLIB600.LIB and is located in the Lib folder. Using Library Quick Pick you can view and retrieve library data from the element editors in your project.Cable SystemsData integration between the one-line diagram and underground raceway system (UGS) includes electrical properties, routing, and physical attributes of cable.Cables in ETAP are categorized in three groups: One-Line, Equipment, and UGS. In future labs we shall be studying each type in detail.

Project Toolbar

The Project toolbar contains buttons that allow you to perform shortcuts of many commonly used commands in ETAP. All of these commands are described in detail in different parts of this manual such as One-Line Diagram Menu Bar and One-Line Diagram Presentation which explains the graphical user interface of the one-line diagram.New:  Create a new project fileOpen: Open an existing project fileSave: Save the project filePrint:  Print active interface views like one-line diagrams or underground raceways.Print Preview:  Preview the print layout of the active interface view.Cut: Cut the selected elements from an active interface view.Copy: Copy the selected elements from an active interface view.Paste: Paste elements from a dumpster cell to an active interface view.Pan: Pan the one-line diagram or underground raceway view using a mouse.Zoom In: Magnify the one-line diagram or underground raceway system.Zoom Out: Reduce the one-line diagram or underground raceway system.Back: Undo zoom level for the one-line diagram.Forward: Redo the zoom level for the one-line diagram.Zoom to Fit Page: Resize the one-line diagram to fit the window.Text Box: Click to place a textbox on an active interface view.Show Grid Lines: Display the grid lines on the one-line diagram.Check Continuity: Check the system continuity for non-energized elements.Hyperlink:  Click to add a hyperlink to a device or one-line diagram.Power Calculator: Activate Power Calculator.Find: Click to find a device on the one-line diagram.Help: Point to a specific area to learn more about ETAP.
