Setting values of the protection function parameters (e.g. I>
menu). See the technical description chapter 2 onward for
appropriate protection function.

Configuration example
The example below illustrates the calculation and scaling of
setting values and the grouping of output relays in a typical
protection configuration. The values given in the example are
to be regarded as guidelines only.
Example: Generator connected directly to busbar
The application uses the following protection functions and
parameters:
•
Definite time overcurrent protection (I>, k, Type)
•
Two-stage overvoltage protection (U>, t>; U>>, t>>)
•
Undervoltage protection (U<, t<, NoCmp, I<Blk)
•
Reverse power (P<, t<)
•
Unbalanced load protection (K1, I2, Type)
•
Underexcitation protection (Q@P0%, Q@P80%, t)
•
Underfrequency protection (f<, t<, Ublock)
•
Overfrequency protection (f>, t>)
