Parallel operation method
You can use this parameter to set the parallel operation method. You can
select the following options:
Option Description
Master The device is designated as
the master. Tap synchronization [ ► Sec-
tion 9.21.1.1, Page 184] par-
allel operation method
Follower The device is designated as
the follower.
Auto. tap synchroniza-
tion Automatic assignment of
master or follower.
If a master is not detected,
the device with the lowest
CAN bus address is auto-
matically designated as the
master. All other devices are
designated as followers.
Circulating reactive
current Circulating reactive current minimization with CAN bus
communication [
► Section 9.21.1.2, Page 185] parallel op-
eration method
Power factor Circulating reactive current minimization without CAN bus
communication [
► Section 9.21.1.3, Page 187] parallel op-
eration method
Tap stagger (optional) The device is designated as the master for the tap stagger
parallel operation method.
Table 64: Setting parallel operation method
Only change the parallel operation method when the on-load tap-changers
are not performing tap-change operations.
CAN bus address
You can use this parameter to assign a CAN bus address to the device. So
that all devices can communicate using the CAN bus, each device requires a
unique identifier. If the value is set to 0, then no communication takes place.
Circulating reactive current sensitivity
You can use this parameter to set the influence of circulating reactive current
on how the control deviation is calculated. The higher the set value, the
greater the calculated control deviation as a result of circulating reactive cur-
rent.
To determine the ideal circulating reactive current sensitivity, note the rele-
vant section in the Commissioning chapter.
