Figure 161: 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 162. 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.
