Fuse Loss (60FL)

The fuse loss (60FL) element detects fuse loss or loss of potential in a three-phase system.
Element logic connections are made on the BESTlogic™Plus screen in BESTCOMSPlus® and element
operational settings are configured on the Fuse Loss (60FL) settings screen in BESTCOMSPlus. A
summary of the logic output and operational settings appears at the end of this chapter.

Element Operation

The 60FL element detects fuse loss and loss of potential by using voltage and current thresholds that are
expressed as a percentage of the nominal voltage and current values. See the
information on changing the nominal voltage and current values.
When the 60FL element logic becomes true, the Fuse Loss output becomes true. A logic diagram is
shown in Figure 170. Logic parameters are shown in Table 92.
Trip Logic: 60FL Trip = (A * C * G * J * P) + (E * F * G * J) (See Table 92.)
Reset Logic: 60FL Reset = H * /K */L (See Table 92.)
