Connecting Current Transformers - Siemens SINAMICS DCM Operating Instructions Manual

Connecting
6.5 Division options
Example 5: Controlling a SITOR thyristor set 6QG12
The information on cables, cable lengths, and module division provided in Example 3 also
largely applies to this example.
The firing pulse transformer module is completely divided up. The small individual boards
containing the firing pulse transformers can be connected to the power unit instead of the
old-style small firing pulse transformer boards. The fuse monitoring and voltage
measurement equipment is mounted in the immediate vicinity of the SITOR set.
