Table64: 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 [►Section 7.5.3.1, Page 82] chapter.
Circulating reactive current blocking limit
You can use this parameter to set the limit value for the maximum permissi-
ble circulating reactive current. This value relates to the rated current of the
current transformer. If, during parallel operation, the circulating reactive cur-
rent exceeds the set limit value, the device triggers the Circulating reactive
current blocking limit exceeded event. All devices operating in the parallel
operation group are blocked.
Desired power factor
You can use this parameter to set the power factor, which the transformer
has under normal operating conditions. If the measured power factor devi-
ates from the desired one, the device calculates a correction which is added
to the control deviation.
Enter a desired power factor other than 0. If you enter a desired power fac-
tor of 0, the device is not able to calculate the voltage correction.
