Marine Electrical Diagram

Electrical Single-Line Diagram & Views

Create, configure, customize, and manage your marine electrical system model. Core modeling and tools allow you to quickly and easily build 3-phase, 2-phase, 1-phase, AC / DC network one-line diagrams with unlimited buses and elements including detailed marine cables, DC Link and protection equipment.

Marine Electrical Diagram
  • Fully integrated view with multiple voltage level handling
  • Unlimited main panel / distribution boards and graphical sub-panels
  • Integrated 3-phase, 2-phase, 1-phase
  • Integrated AC, DC, grounding & earthing systems
  • Multi-level nesting of sub-systems

Auto-Build is an automated and powerful tool for creating and editing the one-line diagram. The rule-based design of Auto-Build can significantly reduce the time spent on creating a one-line diagram.

  • Automated creation of a one-line diagram without leaving the equipment toolbar
  • Quick & intuitive one-line diagram generation
  • Automatic spacing & alignment rules
  • No need to drag, drop, locate, and connect

Add component information, input data, and study results in one block to view on the one-line diagram. 

Datablocks are fully customizable allowing them to be shown, hidden, arranged, and formatted according to the user’s preference. 

Showing properties and results from different studies within the same one-line diagram. Use intelligent text box and hyperlink to include additional customized data to your single-line diagram.
  • Customize input data & study results
  • Display results, tags, and/or properties
  • Define templates & share
  • Automatically apply templates
  • Instant preview of Datablock

Composite Network & Motors

Composite Networks or nested networks allows users to model a portion of their project and represent it as a single element, providing a more simple and organized appearance. Composite networks can be nested for an unlimited number of sub-networks, allowing for multiple layers in one project.

  • Customizable Views
  • Unlimited Connections
  • User-Defined Location & Sizing
  • Visualize Properties & Results

Theme Manager

Set different themes for individual one-line diagrams. Themes can be color coded based on standard, voltage level, area, system grounding, earthing, deenergized elements, feeder, etc. 

Color contouring or user-configurable 'heatmaps' may also be applied behind the one-line diagram. One-line diagram color based contouring is based on voltage or power flow magnitude.

ETAP allows for one-line diagram decluttering based on:

  • Zoom level
  • Equipment type
  • Equipment state
  • Info annotations
  • Study results
  • Datablocks
