Figure 159: 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
160.
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.
