The Relay Group Properties Command in the Main Window lets you review and edit the properties of a relay group. Objects within a relay group include relays, fuse, reclosers and logic schemes. Within the relay-group dialog box, you can (1) edit the parameters of protective devices and logic schemes that are within the group, (2) add new protective devices and logic schemes to the relay group, (3) remove existing protective devices and logic schemes from the group or (4) export relay parameters to a disk file. You can also review and edit coordinating pairs of which the relay group is a member.
To execute this command you must first select the relay group of interest.
Please see Section 5.1 RELAY DIALOG BOXES for explanation of relay, fuse and recloser parameters. Please see SECTION 6 LOGIC SCHEMES for information on logic schemes.
TO REVIEW OR EDIT THE PARAMETERS OF A RELAY GROUP:
1. Select a relay group.
Click the left mouse button once on the relay group you want to review or edit.
The relay group symbol will turn dotted red when selected.
2. Select the Relay | Relay Group Properties command.
A dialog box will appear. The ‘Relay/Breaker Data’ page is on top initially. The list box shows a list of all the relays, fuses and reclosers that are within the relay group. The first device is highlighted.
You can select multiple devices in this list (with mouse clicks with the <Ctrl> or <Shift> key held down) when using the “Show Curve”, “Delete”, “Copy” and “Export” functions.
3. Enter breaker trip logic.
When the trip-logic is set to “Fastest device in group”, OneLiner will compute the trip time as the fastest time among all the tripping relays and logic schemes in the relay group. This is how OneLiner worked prior to V12.
In V12 and later, you can alternatively select in this list box one of the logic schemes. In this case, OneLiner will compute the trip time based solely on the operating time of the selected logic scheme.
Note: if you specify a logic scheme for relay-group trip and the scheme is later deleted or becomes otherwise unavailable, the logic of ‘Fastest device in group’ option will automatically be applied in trip time calculation.
4. Enter the breaker interrupting time in cycles.
The breaker interrupting time is the time between energization of the trip circuit to the extinction of the arc on the primary contacts. The program uses this value for stepped-event simulations.
5. Enter the reclosing logic and reclosing intervals for lines and switches.
Set the number of operations to 1 if there is no reclosing. Set it to 2 if the line/switch recloses once, and so on. The maximum number is 4.
When the number of operations is greater than 1, you must enter the reclosing intervals (in seconds) in the edit boxes provided. The reclosing interval is the time lapse between the opening of the line/switch terminal and the subsequent reclosing operation.
6. Enter a memo.
The memo is for any notes you wish to keep for this relay group. It can have up to 512 characters.
7. Press the button to the right of the text area to enter one or more tags and user-defined data fields for this relay group.
The tags are for organizing objects that are related for some purpose. Please see documentation for Network | Apply Tag for more information.
The user-defined data fields are customizable in File | Preferences dialog box.
TO GET INFO ON A PROTECTIVE DEVICE:
1. Select a single device to review or edit.
2. Press Get Info to review or edit the device parameters.
Note: The Get Info button is enabled only when one, and only one, item is selected in the list box.
A dialog box will appear listing the parameters of the relay, fuse or recloser you selected. Please refer to SECTION 5 RELAY DIALOG BOXES for more information on the dialog boxes of these devices.
TO SHOW RELAY, FUSE OR RECLOSER CURVES:
1. Select one or more devices in the list and press Show Curve.
Note: You can select up to 16 overcurrent devices or 1 distance-relay.
The Relay Group dialog box will disappear. The OC Curves Window or the DS Relays Window will appear showing you the curves or characteristics of the selected devices.
TO TOGGLE THE ON/OFF-LINE STATE OF DEVICE(S):
1. Select one or more device in the list and press On/Off-line.
The indicator to the right of the relay ID will change to reflect the new state. The in-service devices are always listed before the out-of-service devices.
TO ADD A RELAY, FUSE OR RECLOSER TO A RELAY GROUP:
1. Press the Add button. A dialog box will ask you want you want to add.
Mark one of the radio buttons and press OK.
If you selected New Distance Phase or Ground Relay, a “Select a Distance Relay Type” dialog box will appear. The type name is generally the relay's actual trade name. If the relay type name you are seeking is not in the list, you must first exit OneLiner and add the new relay type to the distance relay library using the Distance Relay Editor.
Note: Relay types with names that end with “__”, e.g., “SEL331G__”, are hard coded and therefore cannot be added or removed with the Distance Relay Editor.
Highlight a distance relay type and press OK.
A dialog box for the distance relay will appear. Please refer to section 5.6 DISTANCE GROUND RELAYS for more information on the distance relay dialog box.
If you selected New OC Relay, New Fuse or New Recloser in the “Add New Protective Device” dialog box, a dialog box for the relay, fuse or recloser will appear. Please refer to sections 5.2 OVERCURRENT GROUND RELAYS through 5.5 RECLOSERS for more information on these dialog boxes.
