control and device interface, or a monitoring vehicle or transformer center level, e.g. It is used
for monitoring and reporting with IEC 61850 protocol.
All data under the measurements heading refers to the values on the primary side by looking
at current and voltage transformer ratios.( Main Menu > Configuration > CT/VT Settings ).
These measurements can also be used to verify the proper operation of current and voltage
transformers located in the center during protection and control device tests and
commissioning operations and to verify the secondary connection of the measurement
transformers. According to the device model, only the measured voltage is called VPM; only
the measured current is called CPM
The measurement screens are generally read-only; does not allow data entry.
