Figure 160: Characteristic of load encroachment function
The influence of load encroachment function on the operation characteristic is dependent
on the chosen operation mode of the FRPSPDIS (21) function. When output signal
PHSELZis selected, the characteristic for the FRPSPDIS (21) (and also zone
measurement depending on settings) can be reduced by the load encroachment
characteristic (as shown in figure 161).
