will give higher priority to forcing self-polarization as indicated in the logic below. This is consistent with the overall philoso-
phy of distance memory polarization.
The memory polarization cannot be applied permanently but for a limited time only; the self-polarization may be
applied permanently and therefore should take higher priority.
NOTE
The distance zones of the L60 are identical to that of the UR-series D60 Line Distance Relay. For additional infor-
mation on the L60 distance functions, see the Theory of Operation chapter of the D60 manual, available on the GE
EnerVista CD or free on the GE Digital Energy web page.
