2.2.1. BREAKER FAILURE (50BF)
2.2.1.1. GENERAL DESCRIPTION
The aim of this function is to determine if a failure in the operation of the breaker has
happened. If T seconds after the trip signal the current in any of the phases or neutral
is greater than the preset value the breaker failure signal is sent. T is the Time Delay
setting for this function. If the tripped breaker (52b) digital inputs and the closed
breaker (52a) digital inputs are assigned, the working state of the breaker is also
verified by inspecting these inputs.
Figure 2-48 shows the logical diagram for this function
