Figure159: Setting the transformer data for the reference system
Proceed as follows to set the transformer data:
1. Go to Settings > Parameter > Reference system transformer data.
2. Select the desired parameter and enter the desired value.
3. Press the Accept button to save the modified parameter.
7.15.2 Configuring bushing monitoring
Follow the notes in the following sections when configuring capacitance
monitoring and dissipation factor monitoring.
7.15.2.1 Configuring capacitance monitoring
The device monitors the change in difference of capacitance C1 between the
phases. If the capacitance C1 of all three bushings changes in the same way
(e.g. due to a temperature change), the difference in capacitances ΔC1 re-
mains constant.
