The New Relay Group command in the Main Window lets you create a new relay group for a line, a switch, a phase shifter or a transformer (2- or 3-winding). Initially the relay group contains no relays or logic schemes. To execute this command you must first select a branch.
TO ADD A NEW RELAY GROUP ON A BRANCH:
1. Select a branch.
Click the left mouse button once on the branch to which you want to add a new relay group. For best results, click the mouse near the approximate location where you want the new relay group to be added.
The branch symbol will turn dotted red when selected.
2. Select the Relay | New Relay Group command.
Note: The Relay group menu item is dimmed and cannot be activated if the selected branch already has relay groups on all the terminal buses.
The program will insert a relay group at a terminal bus of the selected branch that is closest to the last mouse click. A dialog box will appear.
The relay-group dialog box has two tabs. The Relay/Breaker Data tab lists all the protective elements that are within the relay group. The Protection Logic tab lists the logic schemes and the coordination pairs.
The Relay/Breaker Data page is shown below.
Please refer to the Relay | RELAY GROUP xe "Properties:relay group"PROPERTIES COMMAND for more information on this dialog box.
