Year of fault
TIME
Time of fault (Hours.Minutes)
SEC
Time of fault (Seconds)

NOTES: The "YES/NO" targets are displayed only if they are "YES".
The angles are not displayed if the magnitude of the value or the reference is less than 0.5 A
or 0.7 V rms.
The impedance is dependent upon the CTYP setting. The internal impedance values are for a
5 A ct. The impedance value is multiplied by 5 if a 1 A ct is used (CTYP = 1).
