If using unequal main C.T.’s the ratio of the lowest primary current to the highest one should not exceed 1:10. When ordering in case of unequal main c.t.`s the ratio of each of them has to be specified absolutely. Unused primary connections have to be open circuited as opposed to the short circuiting of secondary connections.
Please review the following options and select the models that best suit your installation requirements:
CURRENT TRANSFORMER SUMMATION UNTIL 4
The summation current transformers sums up the instantaneous values of diffrent currents in a network, providing a proportional alternating current.
| Main transformers | until 4 |
| Dimensions | 115 x 45 x 73 mm |
| Burden | 15 VA |
CURRENT TRANSFORMER SUMMATION UNTIL 9
The summation current transformers sums up the instantaneous values of diffrent currents in a network, providing a proportional alternating current.
| Main transformers | until 9 |
| Dimensions | 115 x 100 x 73 mm |
| Burden | 15 VA |
Summation current transformers
Summation current transformers SSR-2 to SSR-9 are used to summarize secondary currents of several main c.t.`s in order to measure with one instrument only. The output current again constitutes a standardized quantity. That means the primary currents are not only added but also divided by the number of inputs.

When ordering in case of unequal main c.t.`s the ratio of each of them has to be specified absolutely.
