TRANSFORMER SETTING
•
Rated voltage in IL side (typically high voltage side)
•
Rated voltage in I’L side (typically low voltage side)
•
Rated power of transformer
•
Connection group of transformer
•
Zero current compensation in IL side (If transformer is earthed in
IL side, this must set as “ON”)
•
Zero current compensation in I’L side (If transformer is earthed
in I’L side, this must set as “ON”)
•
Connection group of the unit transformer, if any. IEC marking
with capital letters Y and D for HV side and small case letters y
and d for LV side combined with the dial hour is used. For
example Yd11 means a wye-delta transformer where the delta
side phase-to-ground voltages are leading 30
° the wye side
phase-to-ground voltages.
DEVICE INFO
•
Relay type (Type ALLEN BRADLEY 865)
•
Serial number (SerN)
•

DATE/TIME SETUP
•
Day, month and year (Date)
•
Time of day (Time)
•
Date format (Style). The choices are "yyyy-mm-dd",
"dd.nn.yyyy" and "mm/dd/yyyy".
CLOCK SYNCHRONISATION
•
Digital input for minute sync pulse (SyncDI). If any digital input
is not used for synchronization, select "".
•
Daylight saving time for NTP synchronization (DST).
•
Detected source of synchronization (SyScr).
•
Synchronization message counter (MsgCnt).
•
Latest synchronization deviation (Dev).
The following parameters are visible only when the access level is
higher than "User".
•
Offset, i.e. constant error, of the synchronization source (SyOS).
•
Auto adjust interval (AAIntv).
•
Average drift direction (AvDrft): "Lead" or "lag".
•
Average synchronization deviation (FilDev).
