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
SEF/REF as an SEF input. Use
of the input for high-impedance
REF requires an additional
setting resistor, and may also
require a metrosil.
