Symptom
Transformers should be simultaneously part of two transformer groups. This cannot be realized in the SAP standard, as the system always considers a device group as a unit.
Example:
In practice / in the field / at the customer's premises, transformer cascades are installed.
This means that 6 current transformers use 3 voltage transformers and they are assigned to 2 meters. For this reason, 2 device groups must be built in SAP Utilities, in each of which 3 current transformers and the 3 voltage transformers must be combined.
Meter 1 - Current transformer 1 / 2 / 3 - Voltage transformer A / B / C - device group 1
Meter 2 - current transformers 4 / 5 / 6 - voltage transformers A / B / C - device group 2
The device groups can differ in the transformer factor (transformer constant/multiplication constant) due to the different possible device characteristics.
