MR tapcon 240 - Transformer data; Setting the primary transformer voltage

Transformer data
The transformation ratios and measuring set-up for the voltage and current
transformers used 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.
The following parameters are available for this purpose:
▪ Primary voltage
▪ Secondary voltage
▪ Primary current
▪ Secondary current (current transformer connection)
▪ Transformer circuit
The measured values displayed for the device are influenced by the settings
for the above parameters. Note the table below.

Setting the primary transformer voltage
This parameter can be used to set the primary transformer voltage in kV.
When you are setting the primary transformer voltage, the device shows the
primary voltage rather than the secondary voltage in the main screen and
you can also set the control parameters in kV.
If a setting of 0 kV is chosen, no primary transformer voltage is displayed.
To set the primary transformer voltage, proceed as follows:
