CHAPTER 5: SETTINGS
The C60 relay supports one fault report and an associated fault locator per CT bank to a maximum of four. The signal
source and trigger condition, as well as the characteristics of the line or feeder, are entered in this menu.
The fault report stores data, in non-volatile memory, pertinent to an event when triggered. The captured data contained in
the FaultReport.txt file includes:
• Fault report number
• Name of the relay, programmed by the user
• Firmware revision of the relay
• Date and time of trigger
• Name of trigger (specific operand)
• Line or feeder ID via the name of a configured signal source
• Active setting group at the time of trigger
• Pre-fault current and voltage phasors (two cycles before either a 50DD disturbance associated with fault report
source or the trigger operate). Once a disturbance is detected, pre-fault phasors hold for three seconds waiting for the
fault report trigger. If trigger does not occur within this time, the values are cleared to prepare for the next disturbance.
• Fault current and voltage phasors (one cycle after the trigger)
• Elements operated at the time of triggering
• Events — Nine before trigger and seven after trigger (only available via the relay web page)
• Fault duration times for each breaker (created by the breaker arcing current feature)
The captured data also includes the fault type, the distance to the fault location, distance to the fault location, fault loop
impedance, as well as the reclose shot number (when applicable). To include fault duration times in the fault report, enable
and configure the breaker arcing current feature for each of the breakers. Fault duration is reported on a per-phase basis.
The relay allows locating faults, including ground faults, from delta-connected VTs. In this case, the missing zero-sequence
voltage is substituted either by the externally provided neutral voltage (broken delta VT) connected to the auxiliary voltage
channel of a VT bank, or by the zero-sequence voltage approximated as a voltage drop developed by the zero-sequence
current, and user-provided zero-sequence equivalent impedance of the system behind the relay.
