IGS> T Curve
Selection of which curve will be used for ANSI 51GS: ground surge overcurrent.
IDMT: parametric curve, given by the IGS> T Del and IGS> T Lim parameters as described
in the chapter ground surge time-overcurrent protection.
Mod Inv: moderately inverse curve according to ANSI standard
Very Inv: very inverse curve according to ANSI standard
Ext Inv: extremely inverse curve according to ANSI standard
IECInv: moderately inverse curve according to IEC standard
IECVerInv: very inverse curve according to IEC standard
IECExtInv: extremely inverse curve according to ANSI standard
Default setting: IDMT
IGS Trp BO [Trp 1 / Trp 2 / Trp 1+2 / None]
Selection of trip binary output for ground surge overcurrent protection.
Default setting: None
