To use the power factor method, you need to know the conditions of your
network in order to correctly set the device parameters.
The power factor method is suited to transformers connected in parallel with
a similar nominal output and short-circuit voltage U
K
and to vector groups
with the same and different step voltages. This does not require any informa-
tion about the tap position.
For the circulating reactive current minimization parallel operation method
without CAN communication, you have to set the following parameters:
▪ Activating parallel operation
▪ Parallel operation method: Power factor
▪ Circulating reactive current sensitivity
▪ Circulating reactive current blocking limit
▪ Desired power factor
▪ Desired load stress type
▪ Parallel operation error delay time
Note that the parameters "Error if no communication" and "Behavior if no
communication" have no function in the circulating reactive current mini-
mization without CAN communication parallel operation method.
8.9.2 Configuring parallel operation
In the Parallel operation menu item, you can set the parameters needed for
parallel transformer operation.
Figure 68: Setting parallel operation
The following sections describe how you can set the parameters.
