Figure 6.
The multi breaker packages for single- and three phase tripping typical arrangement for one protection sub-system is shown here.
Auto-reclose, Synchrocheck and Breaker failure functions are included for each of the two breakers.
The basic delivery includes one binary input module and one
binary output module, which is sufficient for the default
configured IO to trip and close circuit breaker. All IEDs can be
reconfigured with the help of the application configuration tool
in PCM600. The IED can be adapted to special applications and
special logic can be developed, such as logic for automatic
opening of disconnectors and closing of ring bays, automatic
load transfer from one busbar to the other, and so on.
The basic IED configuration is provided with the signal matrix,
single line diagram and the application configuration prepared
for the functions included in the product by default. All
parameters should be verified by the customer, since these are
specific to the system, object or application. Optional functions
and optional IO ordered will not be configured at delivery. It
should be noted that the standard only includes one binary
input and one binary output module and only the key functions
such as tripping are connected to the outputs in the signal
matrix tool. The required total IO must be calculated and
specified at ordering.
The configurations are as far as found necessary provided with
application comments to explain why the signals have been
connected in the special way. On request, ABB is available to
support the re-configuration work, either directly or to do the
design checking.
