4 Good to Know for Commissioning
Direction Determination
Direction determination is available only for protection devices that are able to measure
phase currents and voltages.
If direction determination is available then it is a feature of the module Prot ("Module
General Protection", see
It is important to know that the general convention for all E-Series protection devices
is that "Forward" direction always points towards the main object to be protected. For
example, this means for a generator protection device that a "Forward" fault is not in
direction towards the power system, it is rather in direction towards the generator.
Adaptive Parameter Sets
By means of Adaptive Parameter Sets you can modify dynamically single parameters within
the parameter sets of a protection module.
Adaptive Parameter Sets are available only for a few protection modules (essentially only
the overcurrent protection modules).
From the practical point of view, there is one essential difference to the ordinary
parameters sets (see
parameter set affects all protection functions at once. This can increase your
commissioning and testing efforts considerably if you "only" want to modify the behavior
of one particular protection function.
Contrast to this, Adaptive Parameter Sets are "local", i. e. they are effective only within
the protection function where they had been activated. (See below how to do this.)
You can assign a digital signal to any of the parameters [Protection Para / Global Prot
Para / I-Prot / "module"] »AdaptSet 1«, ..., »AdaptSet 4«. ("module" means the name of a
protection module that features Adaptive Parameter Sets, for example: [I[1]]).
These four assignment parameters are always "Global Parameters" (i. e. within the menu
branch [Protection Para / Global Prot Para]). For example, let us make the following
assignment: »AdaptSet 1« = "V[1] . Pickup", see the upper dialog window ① in the
diagram below.
With this assignment, the PowerPort-E dialog window for the "Setting Group Parameters",
for example the menu branch [Protection Para / Set 1 / I-Prot / I[1]], is getting enhanced by
an additional column ②, as shown in the bottom dialog window in the diagram below.
