Figure 1-2. Percentage Restraint Characteristic
Second-Harmonic Restraint Inhibit of the restrained output occurs when the second-
harmonic component exceeds a pickup setting which is 12%
of the operating current for single-phase units or 18% for
three-phase units.
Fifth-Harmonic Restraint
Inhibit of the restrained output occurs when the fifth-harmonic
component exceeds a pickup setting which is 35% of the
operating current.
Unrestrained Output
Pickup Range
Front panel thumbwheel switches adjust the pickup point of
the unrestrained output over a range of 6 to 21 times the tap
setting in increments of 1 x Tap.
Pickup Accuracy
±
3% of the front panel setting.
