25 Complex fast curve - phase N Y/N
The Complex fast curve - phase setting enables the following three settings for the phase fast curve, if set to
Y.
• This setting is hidden and set to N if Fast curve - phase (No. 8) is set to OFF.
Setting Default Range Incr.
Const. time adder - phase
fast curve
0.00 0-60.00 cycles 0.25 cyc.
The Const. time adder - phase fast curve setting adds a constant time to the phase fast curve, if set
to other than 0 cycles.
• This setting is hidden and set to zero (0) if Complex fast curve - phase is set to N.
Setting Default Range Incr.
Vert. multiplier - phase fast
curve
1.00 0.10 - 2.00 0.01
The Vert. multiplier - phase fast curve setting shifts the phase fast curve in time, by the entered
multiplier, if Fast curve - phase (No. 8) is programmed with a recloser or user curve. If no particular
multiplier is desired, set Vert. multiplier - phase fast curve equal to 1.00.
• If Fast curve - phase (No. 8) is programmed with a US (U1-U5) or IEC (C1-C5) curve, Vert.
multiplier - phase fast curve is hidden and nonoperative. The preceding Time-dial - phase fast
curve (No. 8) subsetting provides the US and IEC curves with an effective vertical multiplier,
instead.
• This setting has no multiplying effect on the Constant time adder - phase fast curve and Min.
response time - phase fast curve settings. They all operate independently.
• This setting is hidden and set to 1.00 if Complex fast curve - phase is set to N and Fast
curve-phase (No. 8) is programmed with a recloser or user curve.
Setting Default Range Incr.
Min. response - phase fast
curve
0.00 0-60.00 cycles 0.25 cyc.
The phase fast curve can trip no faster than the Min. response time - phase fast curve setting.
If the Min. response time - phase fast curve setting is set equal to zero (0), it has no effect on the
phase fast curve. If the Min. response time - phase fast curve setting is set equal to 15 cycles, for
example, the phase fast curve cannot trip on the portion of the curve that is faster than 15 cycles - the
phase fast curve effectively flattens out at 15 cycles.
• This setting is hidden and set to zero (0) if Complex fast curve - phase is set to N.
No. Setting Default Range Incr.
26 Complex fast curve - ground N Y/N
The Complex fast curve - ground setting enables the following three settings for the ground fast curve, if set
to Y.
• This setting is hidden and set to N if Fast curve - ground (No. 9) is set to OFF.
Setting Default Range Incr.
Const. time adder - ground
fast curve
0.00 0-60.00 cycles 0.25 cyc.
The Const. time adder - ground fast curve setting adds a constant time to the ground fast curve, if
set to other than 0 cycles.
• This setting is hidden and set to zero (0) if Complex fast curve - ground is set to N.
