UMG 96RM-E
Total current measurement
If the current measurement is done via two current
transformers, the overall transformation ratio
of the current transformers must be programmed into
the UMG 96RM-E.
Example: The current is measured via two current
transformers. Both current transformers have
a transformation ratio of 1000/5A. The total measurement
is done using a total current transformer 5+5/5A.
The UMG 96RM-E must then be setup as follows:
Primary current:
1000A + 1000A = 2000A
Secondary current: 5A
