When the calculated negative phase-sequence voltage value U2s exceeds the set start
value of the stage U2>, the stage generates a start signal after a 50 ms' start time.
When the set operate time at definite-time characteristics or the calculated operate
time at IDMT characteristics elapses, the stage generates a trip signal. The stage is
reset in 70 ms after the calculated negative phase-sequence voltage value has fallen
below the set start value of the stage.
The negative phase-sequence voltage is calculated as follows:
U2s = U a U aU 12 + × +× 2
23 31
3 (1)
a =1∠ 120°
a
2 = 1∠ -120°
The negative phase-sequence value is scaled to the amplitude of the measured
voltage. On a network with a reverse phase order, the calculated negative phasesequence value has the same amplitude as the measured voltage signal.
Stage U2> can be set to be blocked when one of the measured phase-to-phase
voltages falls below 0.15 × Un. The selection is made in SGF4.
Stage U2> has a fixed drop-off/pick-up ratio of 0.96.
5.1.4.3. Undervoltage protection
The undervoltage protection can be based on either conventional voltage
measurement or the calculated positive phase-sequence voltage.
The low-set undervoltage stage UThe low-set stage can also be used for alarm purposes.
The high-set undervoltage stage U<* Conventional voltage measurement (U<* Calculated positive phase-sequence voltage (U1
