CHAPTER 6: ACTUAL VALUES 6.2 STATUS
GEK-106310-AF F650 DIGITAL BAY CONTROLLER 6-31
• PreFault values: Prefault values for all the current and voltage units (Modulus (mod), Angle (deg))
• P
ostFault values: Postfault values for all the current and voltage units (Modulus (mod), Angle (deg))
• R
Primary/ R Secondary: Primary/ Secondary Fault Resistance; this value represents the resistance in primary/
secondary values of the portion of the affected line until the defect.
• Se
condary fault resistance: Resistance of Positive sequence x distance / Line Lenght;
• X Primary/X Secondary:
Primary/ Secondary Fault Reactance. This value represents the reactance in primary/
secondary values of the portion of the affected line until the defect.
• Se
condary fault reactance: Reactance of Positive sequence x distance / Line Lenght;
• Fault r
esistance: This value provides the estimated ground fault resistance in primary values of the fault
seen by the F650 by neglecting the resistance of the affected portion of the line.
• F
ault report trigg: This signal indicates whether the signal that initiates the calculation of the distance to
the fault has been activated.
• Clear fault
reports: This signal indicates the reset of fault reports.
• F
ault date: Date and time of the last fault produced in the relay. In format (Day/Month/year
Hour:minutes:seconds.milliseconds)
• F
ault type: Type of the last fault produced in the Relay (phase to ground, phase to phase, three-
phase, etc).
• F
ault location: Location of the last fault produced in the relay.
• Fa
ult report number: Number of fault reports
