NOTICE!
The „nominal current“ (rated current) In is for all Earth (Ground) Overcurrent stages
dependent on whether the ground (earth) current is measured or calculated. This is
especially true of all settings parameters that are dened in units of In.
• Measured ground (earth) current, [Field Para / General Settings] »CT . IG Source« =•
“measured”:
In is the rated current of the ground (earth) CT, and the WIC1 currently supports 1 A
ground (earth) CTs.
•
Calculated ground (earth) current, [Field Para / General Settings] »CT . IG Source« =
•
“calculated”:
In is the rated current of the phase CTs, and this corresponds to the setting [Field
Para / CT] »CT . In,relative«. (See also ╚═▷ “11.1.3 Setting of the Rated CT current
In” and ╚═▷ “4.2 Field Parameters”.)
