32P/32Q Directional
Power
F-PRO provides directional real power and reactive power protection. Set the
pickup setting to a positive value (trip on forward power flow away from bus)
or a negative value (trip on reverse power flow into bus).
You can set either a real (32P) and a reactive (32Q) direction. The values are
set by specifying the pickup current. This value is set to positive values to de-
tect power flow from the bus and to negative values to detect power flow into
the bus.

Fault Locator When a fault occurs and the line trips, the fault locator calculates the fault type
and the distance to the fault. This information is available from the front dis-
play of the relay or through terminal UI, or SCADA. Enable or disable the fault
locator through 50/51, 50N/51N and 46/50/51 respectively. Define the func-
tions initiating the fault location when setting.
