9.2 Power grid
9.2.1 Transformer data
The transformation ratios and measuring set-up for the voltage and current
transformers used in the system can be set with the following parameters.
The device uses this information to calculate the corresponding measured
values on the primary side of the current transformer (and therefore the
transformer) from the recorded measured values. These are then displayed.
9.2.1.1 Setting transformer data
You can use the following parameters to set the transformer data. Also note
the Examples for standard circuits for current transformers and voltage
transformers.
1. Go to
Settings > Parameters > Grid > Transformer data
.
2. Select the desired parameter.
3. Set the desired parameter.
4. Press the
Accept
button to save the modified parameter.
Primary transformer voltage
You can use this parameter to set the primary voltage of the voltage trans-
former in kV.
Secondary transformer voltage
You can use this parameter to set the secondary voltage of the voltage
transformer in kV.
Primary transformer current
You can use this parameter to set the primary current of the current trans-
former.
Secondary transformer current
You can use this parameter to set the secondary current of the current trans-
former. You can select the following options:
▪ 1 A
▪ 5 A
