Timing Mode
Definite Timing
Setting Range ........................................................... 50 to 600,000 ms
Accuracy....................................................................
±0.5% or ±2 cycles, whichever is greater
Inverse Timing
Setting Range ........................................................... 0 to 9.9

±5% or ±2 cycles, whichever is greater
Refer to the
Time Curve Characteristics chapter for
information on available timing curves.
32 - Power Protection
Pickup
5 Ampere CT Setting Range ..................................... 1 to 6,000 W, three-phase
1 Ampere CT Setting Range ..................................... 1 to 1,200 W, three-phase
Accuracy....................................................................
±3% of setting or ±2 watts, whichever is greater,
at unity power factor. (Accuracy of phase
relationship measurement between V and I is
accurate to within 0.5 degrees when I is greater
than 0.1 Aac and V is greater than 5 Vac. The
power and var measurements at power factor
other than 1.0 are affected accordingly.)
Dropout ...................................................................... 95 to 99% of the actual pickup value
Time Delay
Setting Range ........................................................... 50 to 600,000 ms
Accuracy....................................................................
±0.5% or ±2 cycles, whichever is greater
40Q - Loss of Excitation Protection - Reverse var Based
Pickup
5 Ampere CT Setting Range ..................................... 1 to 6,000 var
1 Ampere CT Setting Range ..................................... 1 to 1,200 var
Accuracy....................................................................
±3% or ±2 var, whichever is greater
Dropout ...................................................................... 93 to 99% of the actual pickup value
Time Delay
Setting Range ........................................................... 1 to 600,000 ms
Accuracy....................................................................
±0.5 or ±2 cycles, whichever is greater
40Z - Loss of Excitation Protection - Impedance Based
Offset impedance mapping can be used to protect against a loss of field (under impedance). Two circular
tripping zones are used on the impedance plane (R and X). Figure 332 illustrates 40Z offset impedance
mapping.
