Protection functions
Description
Enable high set stage
Slope of the third line of the operating
characteristics
Selects if the 2. harmonic deblocking is allowed
in case of switch on to a fault (Allow / Do not
allow)
The ratio of the 5. harmonic to fundamental
component required to remove 5. harmonic
blocking
Selects if the 5. harmonic deblocking is allowed
in case of severe overvoltage situation (Allow /
Do not allow)
Description
Operation Disable / Enable
CT connection type. Determined by the
directions of the connected current
transformers
Connection of the HV side windings.
Determined by the transformer connection
group (e.g. Dyn11 ->"D")
Connection of the LV side windings.
Determined by the transformer connection
group (e.g. Dyn11 ->"yn")
Setting the phase shift between HV and LV with
clock number for connection group
compensation (e.g. Dyn11 -> 11)
Elimination of the zero-sequence current: 1 ->
not eliminated, 2-> on HV only, 3 -> on LV only,
4 -> both on HV and LV
