1. Go to Settings > Parameters > On-load tap-changer regulator > Com-
pensation.
2. Select the desired parameter.
3. Set the desired parameter.
4. Press the Accept button to save the modified parameter.
Voltage increase
You can use this parameter to set the current-dependent voltage increase
∆U.
Voltage limit value
You can use this parameter to define the maximum permissible voltage in-
crease to avoid excess voltage on the transformer.
9.3.3 Parallel operation
Parallel transformer operation is used to increase the throughput capacity or
short-circuit capacity at one location. The device provides you with specific
functions for regulating transformers.
Conditions for parallel
operation
Compliance with the following general conditions is required for operating
transformers in parallel:
▪ Identical rated voltages
▪ Transformer power ratio (<3:1)
▪ Maximum deviation of short-circuit voltages (U
K
) for transformers con-
nected in parallel <10%
▪ The same number of switching groups
▪ For parallel operation with CAN communication: Current transformers with
the same connection values must be used for all devices operating in par-
allel
9.3.3.1 Parallel operation methods
You can undertake parallel operation with various parallel operation meth-
ods.
