action. If a target is enabled for the element, the BE1-11m will record a target when the Trip output
becomes true. See the

Fault Reporting

chapter for more information about target reporting.

If the pickup condition subsides before the element delay or calculated inverse time expires, the timer and
Pickup output are reset, no corrective action is taken, and the element is rearmed for any other
occurrences of overvoltage.

Element Blocking

Fuse Loss

The fuse loss (60FL) element of the BE1-11m can be used to block 59P protection when fuse loss or loss
of potential is detected in a three-phase system.

If the 60FL element trip logic is true and Block Phase/V1 is enabled, all functions that use the phase
voltage are blocked. See the

Fuse Loss (60FL)

chapter for more information on the 60FL function.

Protective elements blocked by 60FL should be set so that trip times are 60 milliseconds or greater to
assure proper coordination of blocking.

Block Logic Input

The Block input provides logic-supervision control of the element. When true, the Block input disables the
element by forcing the Trip and Pickup outputs to logic 0 and resetting the element timer. Connect the
element Block input to the desired logic in BESTlogicPlus. When the element is initially selected from the
Elements view, the default condition of the Block input is a logic 0.

Logic Connections

Overvoltage element logic connections are made on the BESTlogicPlus screen in BESTCOMSPlus. The
overvoltage element logic block is illustrated in Figure 34. Logic inputs and outputs are summarized in
Table 9.
