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.
