UMG 96RM-M
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-M.
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
