Inverse Time, Definite Time and Instantaneous operation is available.Setting current range: 10 - 1260 A22.4Sequence CoordinationSequence Coordination allows a recloser to coordinate it's trip sequence withanother recloser downstream22.5Auto-re-closerRelay 79 (sequence 1,2,3,4)Operating SequenceReclose times are individually selectable. The operating sequence is defined by:O - 1st rt - CO - 2nd rt - CO - 3rd rt - COwhere rt = reclose time.where O = open.where C = close.1st Reclose Time range: 0.2 - 180 sec2nd Reclose Time range: 2.0 - 180 sec3rd Reclose Time range: 2.0 - 180 secTiming resolution: 0.1 secRecovery/ Reset Time: 0.1 - 180 secSequence Reset Timing resolution: 1 sec22.6Trips to LockoutOvercurrent and fault trips to lockout are selectable between 1 and 4. A separatesetting is available for Sensitive Earth Fault and Negative Phase Sequence.22.7Loss of phaseLoss 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 - 15kVVoltage resolution: 1VTime range: 0.1 - 100 secTime resolution: 0.1 sec22.8Live load blockingLive load blocking prevents a re-closer from closing if any of the load side terminalsare live.Live Load Threshold Voltage range: 2 - 15kV22.9Dead lockoutDead lockout prevents a reclose unless one or more of the source side or load sideterminals are live. If all terminals are dead, then the controller goes to lockout22.10Envelope and low frequencyThis feature trips the re-closer when the system frequency exceeds the under andover frequency trip threshold values. Frequency tripping range: 45 - 65 HzRelay 81Frequency calculation: once per cycle over a two-cycle periodNumber of under/over frequency cycles before tripping: 2 - 1000Accuracy: ±0.05Hz22.11Over voltageRelay 5922.12Low voltageRelay 2722.13DistanceRelay 2122.14Directional blockingDirectional protection67 relay PGQ/67Na protection feature that restricts tripping on faults to adesignated side of the re-closer. It prevents nuisance tripping if networkconditions are causing "false" earth faults. In radial systems, Directional Blockingprevents 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 mayuse a different time-current curve and settings to a reverse fault (i.e. these areindividually selectable). Both the forward protection and reverse protection areoperating at the same time. This is an additional protection feature22.15Cold load picks up(OPTIONAL)Cold load pick-up allows for a loss of diversity when a load has been without supplyfor a period.Multiplier range: 1 - 5Multiplier resolution: 0.1Time Constant range: 1 - 480 minTime constant resolution: 1 min22.16High impedance/conductor broken failureOptional22.17harmonicoptional22.18Protection time-current curves:1.
