What happens to the transformer data if the transformer has change in sensor allocation?

From June 2022, the Ecostruxure Transformer Expert product has been changed to be transformer asset-centric, rather than sensor-centric in terms of datasets. Therefore, any data logged for a given transformer is not lost if that transformer has a change in its sensor allocation.  The measured (and derived) data from any sensor continues to be linked with a transformer.  There will only be gaps in datasets for time periods where a transformer has no assigned sensor. 

This functionality enables a replacement sensor to be installed in a transformer and data from the previous and new sensor will be automatically concatenated.  It also enables a distributor to test a sensor in the workshop, but not include that test data in the calculations by choosing the correct date of physical installation in the target customer transformer.
