2.2.5. FUSE LOSS DETECTION (60FL)
This function allows, for the determination, of a voltage loss because of a fuse failure. In
this case the overcurrent characteristics lose their directional property recovering it once
the voltage levels are recovered. This condition is produced when the negative
sequence voltage is higher than the settings value and the negative sequence current is
lower than its settings value.
