Description
Signal for starting in Zone 4 (excepting
when Zone 4 is being used as an
overreaching zone).
Signal for starting in the final zone.
Measurement by the distance function
(Zones 1, 2, 3, 4 or the final zone).
Measurement in the distance protection
overreach zone.
Measurement by the distance protection in
the forwards direction.
Measurement by the distance protection in
the reverse direction (reverse zone).
Tripping by the 'weak infeed' function.
Power-swing blocking function picked up.
VT supervision picked up.
Delayed operation of the VT supervision
after 12 s.
Signal generated when a transfer trip signal
is transmitted.
Signal for boosting PLC transmitting power.
Signal indicating a deviation of the memory
voltage frequency.
