About this chapter
This chapter describes the IED configurations.
Introduction
There are six different software alternatives with which the IED can be ordered. The
intention is that these configurations shall suit most applications with minor or no
changes. The few changes required on binary input and outputs can be done from the
Signal Matrix tool in the PCM600 engineering platform.
The main protection functions are switched Enabled and fully operative at delivery
whereas back-up functions not generally used will be set toDisabled.
The configurations are:
• Two-winding transformer. Single-breaker arrangement.
• Two-winding transformer. Multi-breaker arrangement.
• Three-winding transformer. Single-breaker arrangement.
• Three-winding transformer. Multi-breaker arrangement.
The Multi-breaker arrangement includes Breaker-and-a-half and Ring-breaker
arrangements.
The number of IO must be ordered to the application where more IO is foreseen to be
required in the Multi-breaker arrangement.
However, all IEDs can be reconfigured with the help of the ACT configuration tool in
the PCM600 engineering platform. This way the IED can be made suitable for special
applications and special logic can be developed, that is logic for automatic opening of
disconnectors and closing ring bays, automatic load transfer from one busbar to the
other, and so on.
ABB will of course, on request, be available to support the re-configuration work,
either direct or to do the design checking.
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
