Figure 4-98: Wattmetric characteristic angle response

POWER PICKUP DELAY

Range: 0.000 to 6000.000 s in steps of 0.001 s

Default: 0.200 s

The setting defines a definite time delay before the inverse time characteristic is

activated. If the curve selection is set as "Definite Time" the element operates after this

security time delay. If the curve selection is "Inverse," or one of the FlexCurves, the

element uses both the definite and inverse time timers simultaneously. The definite time

timer specified by this setting, is used, and when it expires it releases the inverse time

timer for operation (torque control).
