Fundamental Harmonics Measurements Menu
Fundamental Harmonics Measurements Menu
displays
the measurements of fundamental harmonics (f= 50 Hz
/ 60 Hz) of the primary R, S, T phases and the primary
earth current. The display menu is shown on the left.
Using
RMS Current Measurements Menu
and
Fundamental Harmonics Measurements Menu
together,
administrators can easily evaluate the TDH (Total
Harmonic Distortion) on the line.
Note that the values shown on the menu are primary
values.
Fundamental harmonics current values are measured
and displayed within the range of (0.1-40.0) I
n
and
(0.1-40.0) I
en
. Values lower than the base limit will
neither be measured nor be displayed, while values
exceeding the upper limit will be evaluated and
displayed as 40 I
n
or 40 I
en
.
For the fact that DEMA CPM 310 G evaluates the
primary current values by utilizing the information
acquired from the secondary signals and the
CT
Settings
menu, the values at the
CT Settings
menu
must be set correctly to make sure
RMS Current
Measurements Menu
displays correct evaluations. □
