Description
Sets the nominal secondary
sensing current to 5 amps
Sets the nominal secondary
auxiliary voltage to 69.3 V
Sets the phase CT ratio to 1
Sets phase VT ratio to 1
Sets phase VT connection
to 4W-Y
Sets 27/59 mode to phase-
neutral
Configures the primary side
for a WYE connection
Disables the primary
winding zero sequence trap
Establishes circuit 1 on the
primary side of the
transformer. For report
labeling purposes only.
Sets the phase rotation of
circuit 1 for ABC
Sets A-phase in circuit 1
equal to the phase
relationship setting for
circuit 2
Configures the secondary
side for a WYE connection
Disables the secondary
winding zero sequence trap
Establishes circuit 2 on the
secondary side of the
transformer. For report
labeling purposes only.
Sets the phase rotation of
circuit 2 for ABC
Sets A-phase in circuit 2
equal to the phase
relationship setting for
circuit 1
Configures the primary side
for a WYE connection
Configures the secondary
side for a WYE connection
with normal ABC phase
rotation
