Current Transformers (CT)
Primary: indicates the current rating of the CT primary.
Secondary: indicates the output current of the CT secondary, either 1A or 5A.
Displays "N/A" if the Order Code indicates no CT is installed in the affected
location.
Voltage Transformers (VT)
Secondary: indicates the output voltage of the VT.
Ratio: the turns ratio of the VT.
Displays "N/A" if the Order Code indicates no VT is installed in the affected
location.
Synchrocheck 1/2 Delta
The Delta values for Synchrocheck 1 and 2, voltage frequency, and phase.
IRIG-B Signal Type
Displays the IRIG-B signal type in use, if applicable.
Normal Frequency
The system nominal frequency in hertz.
Phase Rotation
The system phase rotation, ABC or ACB.
Frequency Tracking Reference
A numerical setpoint value associated with a specific source. The indicated source is
used by the relay for developing frequency metering information. A value of zero
indicates that the relay is not intended to meter frequency.
Hi-Z Function
Enable or Disable the device's High Impedance (Hi-Z) function, if equipped.
