ABB RET670 - Setting Parameters

The value of k=0.92 is recommended in generator applications as the trip delay is
normally quite long.
The calibration factors for current and voltage measurement errors are set % of rated
current/voltage:
IMagComp5, IMagComp30, IMagComp100
VMagComp5, VMagComp30, VMagComp100
IMagComp5, IMagComp30, IMagComp100
The angle compensation is given as difference between current and voltage angle errors.
The values are given for operating points 5, 30 and 100% of rated current/voltage. The
values should be available from instrument transformer test protocols.
