5-220 L60 LINE PHASE COMPARISON SYSTEM – INSTRUCTION MANUALGROUPED ELEMENTS CHAPTER 5: SETTINGS55.6.7 Load encroachmentSETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) LOAD ENCROACHMENTThe load encroachment element responds to the positive-sequence voltage and current and applies a characteristic asshown in the figure.Figure 5-121: Load encroachment characteristicThe element operates if the positive-sequence voltage is above a settable level and asserts its output signal that can beused to block selected protection elements, such as distance or phase overcurrent. The following figure shows an effect ofthe load encroachment characteristics used to block the quadrilateral distance element.
