4.2
DIFF. IN ANGLE:
This setting determines the maximum difference in angle admissible between voltage values at both sides
of the central breaker for a synchronism situation.
4.3
DIFF. IN FREQUENCY:
This setting determines the maximum difference in frequency admissible between voltage values at both
sides of the central breaker for a synchronism situation.
4.4
TEMP. 25/ 79:
This setting determines the minimum time during which the difference in module, phase and frequency
between voltage values at both sides of the central breaker must remain under the values set in 4.1, 4.2 and 4.3.
for a synchronism for reclose condition.
4.5
TEMP. 25/ CLOSE:
This setting determines the minimum time during which the difference in module, phase and frequency
between voltage values at both sides of the central breaker must remain under the values set in 4.1, 4.2 and 4.3.
for a synchronism for close condition.
4.6
RECLOSE PERMISSIONS:
This mask allows to set the situations that must converge for a central breaker reclose permission: 79/ DL-
DB, 79/ LL-DB, 79/ DL-LB and/or 79/ SYNCHECK.
4.7
CLOSE PERMISSIONS:
This mask allows to set the situations that must converge for a central breaker close permission: CLOSE/
DL-DB, CLOSE/ LL-DB, CLOSE/ DL-LB and/or CLOSE/ SYNCHECK.
The names used to describe the settings both for the local MMI and the communications program is limited by the
space available for the identifying texts. For reference, the following is a table of the names used for each setting
in the local display and the GE-LOCAL software.
