2. TIMER SETTINGS
2.1
UNDERVOLTAGE TIMER:
This setting determines the timer for function - A.
2.2
UNDERVOLTAGE' TIMER:
This setting determines the timer for function - A'.
3. 25 SETTINGS FOR 521 (only for MOV2)
3.1
DIFF. IN MODULE:
This setting determines the maximum difference in module admissible between voltage values at both sides
of the side breaker for a synchronism situation.
3.2
DIFF. IN ANGLE:
This setting determines the maximum difference in phase admissible between voltage values at both sides
of the side breaker for a synchronism situation.
3.3
DIFF. IN FREQUENCY:
This setting determines the maximum difference in frequency admissible between voltage values at both
sides of the side breaker for a synchronism situation.
3.4
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 side breaker must remain under the values set in 3.1, 3.2 and 3.3. for
a synchronism for reclose condition.
3.5
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 side breaker must remain under the values set in 3.1, 3.2 and 3.3. for
a synchronism for close condition.
3.6
RECLOSE PERMISSIONS:
This mask allows to set the situations that must converge for a side breaker reclose permission: 79/ DL-DB,
79/ LL-DB, 79/ DL-LB and/or 79/ SYNCHECK.
3.7
CLOSE PERMISSIONS:
This mask allows to set the situations that must converge for a side breaker close permission: CLOSE/ DL-
DB, CLOSE/ LL-DB, CLOSE/ DL-LB and/or CLOSE/ SYNCHECK.
4. 25 SETTINGS FOR 520 (only for MOV2)
4.1
DIFF. IN MODULE:
This setting determines the maximum difference in module admissible between voltage values at both sides
of the central breaker for a synchronism situation.
