The Load Encroachment element responds to the positive-sequence impedance and applies a characteristic shown in the
figure below.
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 QUAD distance element.
