EXAMPLE 2: BREAKER TRIP CIRCUIT INTEGRITY MONITORING
If it is required to monitor the trip circuit continuously, independent of the breaker position (open or closed), a method to
maintain the monitoring current flow through the trip circuit when the breaker is open must be provided (as shown in the fig-
ure below). This can be achieved by connecting a suitable resistor (see figure below) across the auxiliary contact in the trip
circuit. In this case, it is not required to supervise the monitoring circuit with the breaker position – the
BLOCK
setting is
selected to “Off”. In this case, the settings are as follows (EnerVista UR Setup example shown).
Figure 5–151: TRIP CIRCUIT EXAMPLE 2
The wiring connection for two examples above is applicable to both form-A contacts with voltage monitoring and
solid-state contact with voltage monitoring.
