Typical Connection for 3 Phase-fault and Earth-fault Protection
7SG11 Argus 4 Diagrams and Parameters
Notes
1. CT circuits are shown
connected to 1A tap - use
alternative tap for 5A rated
CTs.
2. CT and earth connections
are typical only.
3. Application shows use of
Holmgreen connection for E/F
circuit. Use of separate ring-
core CT is also possible.
