Figure 5–59: PHASE DISTANCE ZONE 2 OP SCHEME
For phase distance zone 2, there is a provision to start the zone timer with other distance zones or loop the pickup
flag to avoid prolonging phase distance zone 2 operation when the fault evolves from one type to another or
migrates from the initial zone to zone 2. Desired zones in the trip output function should be assigned to accomplish
this functionality.
