Setting Default Range Incr.
Vert. multiplier - ground
fast curve
1.00 0.10 - 2.00 0.01
The Vert. multiplier - ground fast curve setting shifts the ground fast curve in time, by the entered
multiplier, if Fast curve - ground (No. 9) is programmed with a recloser or user curve. If no
particular multiplier is desired, set Vert. multiplier - ground fast curve equal to 1.00.
• If Fast curve - ground (No. 9) is programmed with a US (U1-U5) or IEC (C1-C5) curve, Vert.
multiplier - ground fast curve is hidden and nonoperative. The preceding Time-dial - ground
fast curve (No. 9) subsetting provides the US and IEC curves with an effective vertical multiplier,
instead.
• This setting has no multiplying effect on the Constant time adder - ground fast curve and Min.
response time - ground fast curve settings. They all operate independently.
• This setting is hidden and set to 1.00 if Complex fast curve - ground is set to N and Fast curve-
ground (No. 9) is programmed with a recloser or user curve.
Setting Default Range Incr.
Min. response - ground fast
curve
0.00 0-60.00 cycles 0.25 cyc.
The phase fast curve can trip no faster than the Min. response time - ground fast curve setting.
If the Min. response time - ground fast curve setting is set equal to zero (0), it has no effect on the
ground fast curve. If the Min. response time - ground fast curve setting is set equal to 15 cycles, for
example, the ground fast curve cannot trip on the portion of the curve that is faster than 15 cycles - the
ground fast curve effectively flattens out at 15 cycles.
• This setting is hidden and set to zero (0) if Complex fast curve - ground is set to N.
No. Setting Default Range Incr.
27 Complex delay curve - phase N Y/N
The Complex delay curve - phase setting enables the following three settings for the phase delay curve, if set
to Y.
• This setting is hidden and set to N if Delay curve - phase (No. 10) is set to OFF.
Setting Default Range Incr.
Const. time adder - phase
delay curve
0.00 0-60.00 cycles 0.25 cyc.
The Const. time adder - phase delay curve setting adds a constant time to the phase delay curve, if
set other than 0 cycles.
• This setting is hidden and set to zero (0) if Complex delay curve - phase is set to N.
