Summation CT

If you want to add a 2^nd set of Current Transformers through 1 meter, you will need:

• 3 x 2 way summation CTs (SUM-CT-2W).
• 6 x CTs (2 x CTs per Summation CT).

Because the meter is totalling the 2 x sets of CTs, the CT ratio of the meter must be doubled.

For example:

100A supply, the meter needs to be set at 200A.
