ABB RET670 - Setting Parameters; Faulty Phase Identification with Load Encroachment FMPSPDIS

SIRLevel: The setting of the parameter SIRLevel is by default set to 10. This is a
suitable setting for applications with CVT to avoid transient overreach due to the CVT
dynamics. If magnetic voltage transformers are used, set SIRLevel to 15 the highest level.
IMinOp: The minimum operate current for the SIR measurement is by default set to
20% of IBase.
