CHARACTERISTICS
Breaker failure (BF)
Both overvoltage elements can produce the Breaker Failure output if the U> BF and U>>BF pa-
rameters are set to ON.
The parameters are available inside the Set \ Profi le A(or B) \ Overvoltage - 59 \ U> Element (U>>
Element) \ Setpoints menus.
[1]
All the parameters can be set separately for Profi le A and Profi le B (Set \ Profi le A(or B) \ Overvolt-
age - 59 \ U> Element (U>> Element) \ Setpoints menus).
Note 1 The common settings concerning the Breaker failure protection are adjustable inside the Breaker Failure - BF menu.
