Figure 163: Operating characteristic when load encroachment is activated
When the "phase selection" is set to operate together with a distance measuring zone
the resultant operate characteristic could look something like in figure
164. The figure
shows a distance measuring zone operating in forward direction. Thus, the operating
area of the zone together with the load encroachment area is highlighted in black.
