SEL-387E Instruction Manual
Phase Undervoltage Element Pickups (27PnP)
Range
: OFF, 0.1–300.0 V
Set pickups for the phase voltage value below which you want the elements to assert. Note that
n
represents one of two pickup levels, 1 or 2.
Phase-Phase Undervoltage Element Pickups (27PPn)
Range
: OFF, 0.1–520.0 V
Set pickups for the phase-to-phase voltage value below which you want the elements to assert.
Note that
n represents one of two pickup levels, 1 or 2.
Positive-Sequence Undervoltage Element Pickup (27V1P)
Range
: OFF, 0.1–100.0 V
Set the pickup for the positive-sequence voltage value below which you want the element to
assert.
Phase Overvoltage Element Pickups (59PnP)
Range
: OFF, 0.0–300.0 V
Set pickups for the phase voltage value above which you want the elements to assert. Note that
n
represents one of two pickup levels, 1 or 2.
Residual Overvoltage Element Pickups (59GnP)
Range
: OFF, 0.0–300.0 V
Set pickups for the residual voltage value above which you want the elements to assert. Note that
n represents one of two pickup levels, 1 or 2.
Negative-Sequence Overvoltage Element Pickup (59QP)
Range:
OFF, 0.0–100.0 V
Set the pickup for the negative-sequence voltage value above which you want the element to
assert.
Phase-Phase Overvoltage Element Pickups (59PPn)
Range
: OFF, 0.0–520.0 V
Set pickups for the phase-to-phase voltage value above which you want the elements to assert.
Note that
n represents one of two pickup levels, 1 or 2.
Positive-Sequence Overvoltage Element Pickup (59V1P)
Range
: OFF, 0.0–100.0 V
Set the pickup for the positive-sequence voltage value above which you want the element to
assert.
