CURRENT DIFFERENTIAL
The following settings are available for current differential protection.
•
CURRENT DIFF SIGNAL SOURCE 1
: This setting selects the first source for the current differential element local
operating current. If more than one source is configured, the other source currents are scaled to the CT with the maxi-
mum primary current assigned by the
CURRENT DIFF SIGNAL SOURCE 1
to
CURRENT DIFF SIGNAL SOURCE 4
settings. This
source is mandatory and is assigned with the
SYSTEM SETUP
SIGNAL SOURCES
SOURCE 1
menu.
