The load encroachment element responds to the positive-sequence voltage and current and applies a characteristic shown
in the figure below.
Figure 5–79: LOAD ENCROACHMENT CHARACTERISTIC
The element operates if the positive-sequence voltage is above a settable level and asserts its output signal that can be
used to block selected protection elements such as distance or phase overcurrent. The following figure shows an effect of
the load encroachment characteristics used to block the quadrilateral distance element.
