Helpful Hints for Coordinaide™ — The S&C Protection and Coordination Assistant.

Once you become familiar with Coordinaide, you’ll find that it is extremely easy to use. Since it is a web-based program, Coordinaide has a slightly different look and feel than Microsoft Windows®-based programs you’ve used. This article provides some helpful hints that will make your Coordinaide sessions enjoyable and productive.

The two most important things to remember are:

  • Be patient. The pages need time to update. Watch the download status bar at the bottom of the screen. Wait until the pages completely load before selecting the next navigation button.
  • Scroll down. Oftentimes, the next required “selection” is not immediately visible. Use the vertical scroll bar to navigate to the bottom of the page.

Here are some general hints:

  • Do not use the “Back” button on your Internet browser. Use the on-screen menus and navigation buttons.
  • Do not use punctuation characters to break up large numbers (e.g., 40,000 amperes). Only use periods as decimal points (e.g., 12.47 kV).
  • To move from device to device, click on the Navigation buttons at the top of the page (e.g., Device 1, Device 2). Or click on the device single-line diagrams at the bottom of the page.

Some additional hints, grouped by page or function.

“General Information” Page

  • Required Fields (to generate meaningful results):
    • Voltage, kV (Three-Phase)
    • Available Fault Current (RMS Sym. Amperes)
    • At least one protective device should be selected
  • Optional Fields:
    • Project Name
    • Date
    • By (name)
  • Getting Started:
    • Enter General Information (e.g., Name, Date, By).
    • Enter required System Information (e.g., Voltage and Available Fault Current).
    • Select all devices to be included on the coordination graph before pressing “Continue”.
    • “Clear All Fields” will erase all your entered data, and allow you to start over.

“Device” Pages

  • Selecting a Protective Device:
    • Select device attributes from the drop-down menus, working from the top (the protective device closest to the source) to the bottom (the protective device closest to the load).
    • Select “Draw/Redraw” to draw the graph immediately, or
    • Select “Continue” to proceed to the next page (or device).
  • Skipping a Protective Device:
    • Select “Continue” to proceed to the next page (or device).
    • If you want to add a device to a position previously skipped, select “Click to Select a Device” or click on “General Info” at the top of the page. This will direct you back to the “General Information” page.
  • Importing TCC Data for a Protective Device from a Microsoft Excel® spreadsheet:
    • Arrange the data in column format
      • COLUMN 1 — current (descending)
      • COLUMN 2 — time (ascending)
    • Save the data in Excel as a “CSV (Comma-Separated Variable)” text file.
    • Copy and paste separate minimum-melting and total-clearing TCC data sets into appropriate fields on the “User Provided (Import Data Points)” device page.

“Results” Page

  • Scale: Select either button to change the current scale of the graph (i.e., 0.5 to 10000 amperes or 5 to 100000 amperes).
  • Zoom: Enter the starting and ending currents and times to zoom in on a desired section of the coordination plot.
  • Output Curves: Select “Device #” and then “Click to Convert”. Export data to Excel using the “cut” and “paste” functions.
  • Print Reports:
    • Select “Printer Friendly Graph” and use the browser “Print” function.
    • Select “Printer Friendly Summary” and use the browser “Print” function.
  • Click on “Return to General Info” to start over.
