FLEXCURVE A(D)
FlexCurves™ A through D have settings for entering times to reset and operate at the following pickup levels: 0.00 to 0.98
and 1.03 to 20.00. This data is converted into two continuous curves by linear interpolation between data points. To enter a
custom FlexCurve™, enter the reset and operate times (using the VALUE keys) for each selected pickup point (using the
MESSAGE UP/DOWN keys) for the desired protection curve (A, B, C, or D).
The relay using a given FlexCurve™ applies linear approximation for times between the user-entered
points. Special care must be applied when setting the two points that are close to the multiple of pickup of
1; that is, 0.98 pu and 1.03 pu. It is recommended to set the two times to a similar value; otherwise, the lin-
ear approximation may result in undesired behavior for the operating quantity that is close to 1.00 pu.
