Records; Fault Reports - GE D60 Instruction Manual

CHAPTER 6: ACTUAL VALUES
per the following equations.
where
VA, VB, VC are phase voltage phasors in secondary volts
IA, IB, IC are current phasors in secondary amps
I0 is the zero sequence current phasors in secondary amps
IG is the ground current from the parallel line scaled to the source phase CT in secondary amps
Z0/Z1 is the zero sequence impedance to positive sequence impedance ratio
Z0M/Z1 is mutual zero sequence impedance to positive sequence impedance ratio, both are settings taken from the first
enabled ground distance zone (count from zone 1 to zone 5)
ZAG, ZBG, ZCG are calculated only if at least one ground distance zone is enabled; otherwise all the metering quantities for
ground distance impedance (ZAG, ZBG, and ZCG) are reset to zero, including magnitude and angle. Note that VTs of the
distance source must be connected in Wye if the ground distance element is enabled.
