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).
