Description
Common trip, issued when either zone 1 or zone 2 trip
Zone 1 trip
Zone 2 trip
Set when measured impedance enters lens
characteristic
Generator rotates faster than the system during pole slip
Generator rotates slower than the system during pole
slip
Real part of measured positive-sequence impedance %
of VBase/(sqrt(3)*IBase)
Imaginary part of measured positive-seq impedance %
of VBase/(sqrt(3)*IBase)
Default Description
Disabled Operation Enable/Disable
Enabled Operation Zone1 Enable/disable
50.00 Percentage part of total forward impedance;
defines Z1 reach
Enabled Operation Zone2 Enable/disable
0.040 Breaker opening time; use default 0s value if it
is unknown
Default Description
1 Number of pole-slips in zone 1 required for
zone 1 trip
3 Number of pole-slips in zone 2 required for
zone 2 trip
6.000 Time without any slip required to completely
reset function
