Click on the connection point of one component and drag to another to create a connection. 4. Inputting Component Data
The primary workspace in ETAP is the one-line diagram. Tutorials guide users in dragging and dropping components like buses, transformers, generators, and loads from the library onto the workspace. Data Entry and Parametrization:
The One-Line Diagram is the primary graphical interface where you model your system. : Ensure you are in to add or modify components. Adding Elements : Use the toolbar to drag and drop elements such as Transformers Generators Connecting Components
Displays simulation results, errors, and warnings. 3. Building a One-Line Diagram (OLD) The first step in any ETAP tutorial is building the model.
This comprehensive tutorial covers everything from navigating the user interface to running advanced simulation studies. 1. Understanding the ETAP User Interface etap tutorial
Before running simulations, you need to build the electrical network model.
Choose between 2-winding or 3-winding, set MVA, kV, and impedance (
The main workspace canvas where you build your electrical network using graphical icons.
This step-by-step tutorial covers everything from setting up your first project to executing advanced system simulations. 1. Introduction to the ETAP Interface Click on the connection point of one component
This is often the first major simulation taught. Users learn to run a "Power Flow" to calculate bus voltages and branch currents, helping identify overloads or under-voltage conditions. Short Circuit Analysis:
Calculating maximum fault currents to select protective devices based on IEEE/IEC standards .
After launching the ETAP software, go to > New Project . A dialog box will prompt you to enter a project name, choose a storage location, and set the system's base frequency (50 Hz or 60 Hz) and units. Once confirmed, the software will automatically open the drawing environment, ready for you to build your model.
Click the Device Evaluation button. ETAP compares your fault current to the existing breaker ratings. If the rating is lower than the fault, the breaker will turn red—signaling a dangerous mis-coordination. Tutorials guide users in dragging and dropping components
: Assesses the risk of electrical explosions to ensure compliance with safety standards like Relay Coordination
This tutorial provides a comprehensive introduction to ETAP, taking you from building a simple one-line diagram to conducting complex power flow analysis. 1. Introduction to ETAP Software
Ensure that the fault current does not exceed the interrupting capacity of circuit breakers. III. Protective Device Coordination
