Below are the descriptions of the controls existing in
the menu.
Level
Level
parameter sets the multiplication factor of delay
times for the selected functions. The setting range is
from %20 to %500; in other words, delay times can be
multiplied in a range of 0.2 to 5.0. When the setting
value is declared below %100, the CLP function will
behave in inverse characteristics it is intended for. This
kind of application is made available for specific
applications. When the setting value is declared above
%100, the CLP function will behave as described in the
previous paragraphs.
Time
The
Time
parameter determines the duration of CLP
functionality, starting at the moment that the dedicated
input receives the
Start CLP
signal. This duration
determines, at the same time, the moment that the
protection functions will start to behave as they
originally set to.
Covered Functions (Active / Passive)
The entire control lines other than those described in
the previous page are used for declaring CPM 310 G
which protection functions are to be covered by the
CLP functionality. By setting each of the listed functions
as
Active
or
Passive
, the functions that are covered and
excluded are decided. The functions being mentioned
here is listed as follows:
• Phase Overcurrent Protection Functions: I>, I>>,
I>>>.
Earth Overcurrent Protection Functions: I
e
>, I
e
>>,
I
e
>>>.
Negative Sequence Overcurrent Functions: I

>>.
CLP configuration methods vary by numerous
applications. To decide to use CLP, or which functions
are to be included or excluded, examinations with a
number of parameters must be studied. It is
recommended to seek professional help for these
processes. □
