Power Swing: Two functions
Power Swing Blocking (ANSI 68)
Avoids uncontrolled tripping of the distance
protection Operates under symmetrical load conditions as
well as during single-pole auto-reclose cycles
Requires no settings
Can be configured separately to block each
distance zone
Evaluates the impedance trajectory of the
positive sequence impedance Provides a response characteristic with up to 4
impedance zones in the R/X plane
Operates independently from settings of distance
protection zones
Increments counters depending on the point at
which the impedance trajectory enters or exits
the associated impedance zone
Out-of-step protection (ANSI 78)
