Introduction to basics of Electrical Transient Analyser Program (ETAP)
(CLO 1 , PLO 1, 5 )
What is ETAP?
ETAP is the most comprehensive analysis platform for the design, simulation,operation control,optimization and automation of generation, transmission, distribution and industrial power systems. ETAP is a fully graphical electrical power system analysis program that runs on Microsoft® Windows® 2008 R2 (SP1), 2012/R2, 7 (SP1), 8/8.1, 10 operating systems. In addition to the standard offline simulation modules, ETAP can utilize real-time operating data for advanced monitoring, real-time simulation, optimization, and high-speed intelligent load shedding.
ETAP has been designed and developed by engineers for engineers to handle the diverse discipline of power systems in one integrated package with multiple interface views such as AC and DC networks, cable raceways, ground grid, GIS, panels, protective device coordination/selectivity, and AC and DC control system diagrams. ETAP allows you to work directly with graphical one-line diagrams, underground cable raceway systems, three-dimensional cable systems, advanced time-current coordination and selectivity plots, geographic information system schematics (GIS), as well as three-dimensional ground grid systems.
ETAP Wizards:
ETAP includes time-saving project management tools called the ETAP Wizards, which allow you to record and run any study at any time. The ETAP Wizards include the Scenario Wizard, Study Wizard, and Project Wizard. All three are described below. Through the ETAP Wizards, you will be able to combine the orthogonal tools (Presentations, Configurations, and Revision Data), study types, output reports, and study cases (the loading and generation system operation factors together with solution parameters) to perform a complete system study with the click of a button.
Interface Maps:
The following maps are provided to describe the general structure and user interface of ETAP. Edit Mode: Here you can graphically add, delete, relocate, and connect elements, zoom in or out, display grid off or on, change element size, change element orientation, change symbols, hide or show protective devices, enter properties, set operating status, and more.
Menu Bar: The Menu bar contains a comprehensive list of menu options. Each option activates a drop-down list of commands such as, File operations, Printing, Database Conversions, Data Exchange, OLE objects, Project Standards, Project Settings and Project Options, Libraries, Defaults, Annotation Fonts, Base and Revision Data, and more. Project Toolbar : The Project toolbar contains buttons that provide shortcuts for many commonly used functions. Those functions are: Create Projects, Open Projects, Save Projects, Print, Print Preview, Cut, Copy, Paste, Pan, Zoom, Undo, Redo, Text Box, Grid Display, Continuity Check, Themes, Get Template, Add to OLV Template, Hyperlink, Power Calculator, Find, and Help. Theme Toolbar : The Theme toolbar contains buttons that allow you to perform shortcuts using many commonly used commands in ETAP to change color and line styles for device connectors, symbol color, and background. The Theme toolbar consists of the following commands
- Theme manager
- Theme Name
- Theme Color Coding
- Colors Normal
- Colors Customer
- Enable contouring Project View: The Project View is a graphical tree representation that includes Presentations, Configurations, Study Cases, Libraries, and Components associated with your project. Here you can create and manipulate the following presentations, configurations, and study cases:
- One-Line Diagram Presentations
- U/G Cable Raceway Systems
- Ground Grid Systems
- Study Configurations
ETAP provides the following study modes directly from the one-line diagram:
- Load Flow Analysis
- Short-Circuit Analysis
- Arc Flash Analysis
- Motor Acceleration Analysis
- Harmonic Analysis
- Transient Stability Analysis
- Star – Protective Device Coordination
- DC Load Flow Analysis
- DC Short-Circuit Analysis
- DC Arc Flash Analysis
- Battery Sizing and Discharge Calculations

- Contingency Analysis
- Rail Traction Power
- Star Systems
- Underground Raceway Systems
- Ground Grid Systems
- Cable Pulling Systems Cable and ground grid analysis, and cable pulling calculations are available from the Underground Cable Raceway Systems, Ground Grid Systems, and Cable Pulling Systems studies, respectively.
Tutorial:
➢ To begin, start ETAP by double-clicking the icon on your desktop.
The first tutorial shows you how to create a small system. For this section you can use the “New Project” option when the Select Demo Project window appears. For the rest of the tutorials (except for Star), you should use the “Example Project” option instead.
Building a One-Line Diagram:
The purpose of this tutorial is to show the fundamentals of building and manipulating a one-line diagram (OLD) in ETAP. Various elements will be added to the one-line view (OLV), and an introduction to equipment editors will be made. ➢ To build or edit a one-line diagram in ETAP, you must be in Edit Mode. Click the Edit button on the Mode toolbar. ➢ On the AC Edit toolbar, select a Power Grid (Utility) element by clicking on the Power Grid button. The cursor will change to the Power Grid icon when moving over the OLV. Click anywhere in the OLV to place a Utility on your one-line diagram. ➢ By following the same procedure, insert the following elements until your OLD appears as follows and connect them with wire.
