The data in the table are valid for a single IED with 64 Kbits/s communication in the loop-back mode.
*Note: Data obtained with single three-phase input current group. The operate and reset times for L3CPDIF are valid for an static output
from SOM.
**Note: Data obtained with two three-phase input current groups. The rated symmetrical currents are applied on both sides as pre- and
post-fault currents. The fault is performed by increasing one phase current to double on one side and decreasing same phase current to
zero on the other side.
