UMG 96RM
Total current measurement
If the current measurement takes place via two current
transformers, the total transformer ratio of the current
transformer must be programmed in the UMG 96RM.
Example: The current measurement takes place via two
current transformers. Both current transformers have
a transformer ratio of 1000/5 A. The total measurement
is performed with a 5+5/5 A total current transformer.
The UMG 96RM must then be set as follows:
Primary current: 1000 A + 1000 A = 2000 A
Secondary current: 5 A
