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.
Figure 81: Setting transformer data (example)
Setting the primary transformer voltage
This parameter can be used to set the primary transformer voltage in kV.
To set the primary transformer voltage, proceed as follows:
1.
Go to Settings > Parameters > Transformer data > Primary trans-
former voltage .
2. Enter primary transformer voltage.
3. Press the Accept button to save the modified parameter.
Setting the secondary transformer voltage
This parameter can be used to set the secondary transformer voltage in V.
To set the secondary transformer voltage, proceed as follows:
1.
Go to Settings > Parameters > Transformer data > Secondary trans-
former voltage .
2. Enter secondary transformer voltage.
3. Press the Accept button to save the modified parameter.
Setting primary transformer current
This parameter can be used to set the primary transformer current.
