C
• PDIS: phase distance, ground distance
• PIOC: phase instantaneous overcurrent, neutral instantaneous overcurrent, ground instantaneous overcurrent, nega-
tive-sequence instantaneous overcurrent.
• PTOC: phase time overcurrent, neutral time overcurrent, ground time overcurrent, negative-sequence time overcur-
rent, neutral directional overcurrent, negative-sequence directional overcurrent
• PTUV: phase undervoltage, auxiliary undervoltage, third harmonic neutral undervoltage
• PTOV: phase overvoltage, neutral overvoltage, auxiliary overvoltage, negative sequence overvoltage
• RBRF: breaker failure
• RREC: autoreclosure
• RPSB: power swing detection
• RFLO: fault locator
• XCBR: breaker control
The protection elements listed above contain start (pickup) and operate flags. For example, the start flag for PIOC1 is
PIOC1.ST.Str.general. The operate flag for PIOC1 is PIOC1.ST.Op.general. For the F35 protection elements, these flags
take their values from the pickup and operate FlexLogic™ operands for the corresponding element.
Some protection elements listed above contain directional start values. For example, the directional start value for PDIS1 is
PDIS1.ST.Str.dirGeneral. This value is built from the directional FlexLogic™ operands for the element.
The RFLO logical node contains the measurement of the distance to fault calculation in kilometers. This value originates in
the fault locator function.
