You can import relay data into an ASPEN OneLiner binary file by:
1. Create a text file with .RAT extension in the form described in this section. You are responsible for this step.
2. Importing the text file into OneLiner using (1) the Relay | Import Relay command in the Main Window, or (2) the Import button in the relay-group dialog box (see documentation for the Relay | Relay Group Property command).
The relay text data file begins with an optional header section that begins with the line [ASPEN RELAY DATA] and ends with a blank line. The line delimiter=’ or delimiter=” specifies the string delimiter being used. Other information in this section includes the date, and program name and version that generated the file.
The relay data that follow may contain parameters of overcurrent relays, distance relays, fuses and reclosers.
The record for each device begins with a line that identifies the device type - for example, "OC GROUND RELAY" for an overcurrent ground relay. The relay data, on one or more lines that follow, must be arranged in a specific order. The line width is limited to 132 characters.
Adjacent data items for a relay must be separated by a semicolon, plus any number of blanks. Data items containing alphanumeric text, such as bus names, must be enclosed by the string delimiter. You can change the string delimiter in the Network tab of the File | Preferences command.
Data for different relays are separated by one or more blank lines.
Relay data are briefly described in this section. Please refer to SECTION 5 RELAY DIALOG BOXES for more information on relay parameters.
