SEL-787 Settings Sheets
Instruction Manual
These settings sheets include the definition and input range for each setting in the relay. You can access the settings
from the relay front panel and the serial ports.
➤ Some settings require an optional module (see Section 4: Protection and Logic Functions for details).
➤ Some of the settings ranges may be more restrictive than shown, because of settings interdependency
checks performed when new settings are saved (see Setting Entry Error Messages on page 6.6).
➤ The settings are not case sensitive.
