This configuration is used in applications with single breakers with single or double busbars. The protection scheme includes a 1–phase tripping and 1– or 3–phase autoreclosing scheme with a synchronism check.

The differential protection for up to 3 CT sets, 2–3 line ends is the main protection function. It is available with communication modules for single or redundant channels and can be used in two- or multi-terminal arrangements. Measuring functions for S, P, Q, I, U, PF, f are available for local presentation on the local HMI and/or remote presentation.

The availability of additional analog inputs allows connection of separate metering cores and a calibration parameter on the measurement function allows calibration at site to very high accuracy. Optional functions can be ordered and include functions such as full control, local and remote, directional earth fault, out-of-step protection, frequency protection, and so on.

These optional functions must be added to the configuration and loaded into the IED after delivery. The following should be noted. The configuration is made with the binary input and binary output boards in the basic IED delivery. In many cases this is sufficient, in other cases e.g. with full control of all apparatuses included more IO cards are required.

Our proposal for a full version with control is to use three binary input modules and two binary output module. For systems without substation automation, a second binary output board might be required
