Phase Overvoltage (59P) Protection BE1-11m
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 7-2. Logic inputs and outputs are summarized in
Table 7-2.

Disables the 59P function when true
True when the 59P element is in a trip condition
True when the 59P element is in a pickup condition
Operational Settings
Overvoltage element operational settings are configured on the Overvoltage settings screen (Figure 7-3)
in BESTCOMSPlus.
