Name your project and select your preferred unit system ( or Metric ) and standard frequency ( 60 Hz for North America or 50 Hz for international regions). Step 2: Establish the Power Source (Power Grid)

: Open ETAP and click the New Project icon. In the dialog box, enter a name (e.g., "Industrial_Plant_V1") and select the directory where you want to save your files.

Enter the rated power (MVA), voltage ratings ( ), percentage impedance ( ), and tap settings.

Select your preferred system engineering unit system: (typically used in North America, operating at 60 Hz) or IEC (international standard, typically operating at 50 Hz). etap tutorial

Input the rated horsepower (HP) or kilowatts (kW), power factor, efficiency percentage, and operational loading state. Step 4: Running a Load Flow Analysis

Arc flash analysis uses the system model to calculate incident energy and define flash protection boundaries for safety labeling.

Tip: Use the "Library" button in the component editor to automatically populate data for standard components (transformers, cables). 5. Running Load Flow Analysis (Power Flow) Name your project and select your preferred unit

ETAP utilizes an intelligent, multi-dimensional database structure. Unlike basic drafting tools, every element you place on the screen stores rich engineering attributes (e.g., impedance, thermal ratings, curves).

Familiarize yourself with the One-Line Diagram (OLD) workspace, the System Management toolbar (top), and the Edit Toolbar (right), where all your components (generators, buses, transformers) live.

Use the Configuration Manager to switch between "Normal Operation," "Emergency Design," and "Minimum Generation" states without deleting your core design framework. Enter the rated power (MVA), voltage ratings (

Core concepts and model elements

The Star module is ETAP's platform for overcurrent protection and coordination studies, allowing you to create Time-Current Characteristic (TCC) curves and verify selective device tripping.

A Load Flow (Power Flow) analysis calculates bus voltages, power factors, currents, and power losses across the entire network under steady-state conditions.

ETAP is a modular, analytical tool used for simulating electrical systems. It provides comprehensive capabilities for:
