detection of low-level phase-to-phase faults in the presence of high level three phase
loads. Inverse Time, Definite Time and Instantaneous operation is available.		Setting current range: 10 - 1260 A
22.4Sequence CoordinationSequence Coordination allows a recloser to coordinate it's trip sequence with
another recloser downstream
22.5Auto-re-closerRelay 79 (sequence 1,2,3,4)
Operating Sequence
Reclose times are individually selectable. The operating sequence is defined by:
O - 1st rt - CO - 2nd rt - CO - 3rd rt - CO
where rt = reclose time.
where O = open.
where C = close.		1st Reclose Time range: 0.2 - 180 sec

Timing resolution: 0.1 sec
Recovery/ Reset Time: 0.1 - 180 sec
Sequence Reset Timing resolution: 1 sec
22.6Trips to LockoutOvercurrent and fault trips to lockout are selectable between 1 and 4. A separate
setting is available for Sensitive Earth Fault and Negative Phase Sequence.
22.7Loss of phase
Loss of phase protection trips the re-closer if phase-earth voltage on one or two, phases falls below a set voltage threshold for a set length of time.		Threshold voltage range: 2 - 15kV
Voltage resolution: 1V
Time range: 0.1 - 100 sec
Time resolution: 0.1 sec
22.8Live load blocking
Live load blocking prevents a re-closer from closing if any of the load side terminals
are live.		Live Load Threshold Voltage range: 2 - 15kV
22.9Dead lockout
 		Dead lockout prevents a reclose unless one or more of the source side or load side
terminals are live. If all terminals are dead, then the controller goes to lockout
22.10Envelope and low frequency
This feature trips the re-closer when the system frequency exceeds the under and
over frequency trip threshold values. Frequency tripping range: 45 - 65 Hz		Relay 81
Frequency calculation: Once per cycle over a two-cycle period
Number of under/over frequency cycles before tripping: 2 - 1000
Accuracy: ±0.05Hz
22.11Over voltageRelay 59
22.12Low voltageRelay 27
22.13DistanceRelay 21
22.14Directional blocking
Directional protection
 		67 relay PGQ/67N
a protection feature that restricts tripping on faults to a
designated side of the re-closer. It prevents nuisance tripping if network
conditions are causing "false" earth faults. In radial systems, Directional Blocking
prevents nuisance tripping by blocking faults in the source direction and only responding to faults in the load direction.
Distinct protection for faults in the forward and reverse direction. A forward fault may
use a different time-current curve and settings to a reverse fault (i.e. these are
individually selectable). Both the forward protection and reverse protection are
operating at the same time. This is an additional protection feature
22.15Cold load picks up(OPTIONAL)

the Instantaneous Multiplier x Setting Current.		Multiplier range: 1 - 30
Resolution of setting: 0.1
