• Information on the actual status of the system
• Conversion of secondary values to primary values and percentages
Prerequisites
Except for secondary values, the device is able to indicate the primary values and percentages of the measured
values.
A precondition correct display of the primary and percentage values is the complete and correct entry of the
nominal values for the instrument transformers and the protected equipment as well as current and voltage
transformer ratios in the ground paths when configuring the device.
Measured values which cannot be calculated due to the selected voltage connection are shown as dots.
