Description of
06 A A/C Aug 2000
Not released to production
Additional IDMT characteristics for overcurrent protection
(rectifier and RI curve), earth fault protection (RI and IDG
curve) and sensitive earth fault protection (IDG curve)
Change to time dial setting range of IEEE and US curves.
Previously curves were based on TD/7 where TD = 0.5-15.
Now, curves are based on TD where TD = 0.01-100. Also,
includes change to US ST Inverse (C02) curve. K constant
and L constant multiplied x 7 because of change to TD, now
K=0.16758 and L=0.11858
Angle measurements for sequence quantities in
Measurements 1 menu added
Optional 2nd rear communication port added
New power supply with increased output rating and reduced
dc inrush current (typically < 10A). (Model number hardware
changed to suffix C)
Wider setting range for Power and Sensitive Power
protection. P>1/2 (reverse power) and P<1/2 (low forward
power) maximum setting changed from 40In to 300In W
(Vn=100/120V) and from 160In W to 1200In W
(Vn=380/480V). Sen –P>1/2 and Sen P<1/2 maximum
setting changed from 15In to 100In W (Vn=100/120V) and
from 60In to 400In W (Vn=380/480V). There is also an
additional setting for the Power and Sensitive Power
protection to select the Operating mode as Generating or
Motoring
