Results with nominal burden or with operating burden
The measured or calculated results in the MR-Results card can be displayed for
the nominal burden or for the operating burden. Select the burden to be used
using the corresponding soft key
Results with Op. Burden or Results with
Nom. Burden .
• When the results are displayed for the nominal burden, the "VA" and "cos
ϕ
"
fields on the top of the page show for each tap or intertap combination
selected with the cursor in the "Taps" column the assigned nominal burden
and cos
ϕ
used for the measurement (e.g. 25VA for X1-X5, 12.5VA for X1-
X4 etc., as assigned in the MR-Config. card).
Using the Show Inter Taps soft key you can display the intertap
combinations instead of the tap combinations.
• When the results are displayed for the operating burden, the "Burden" and
"cos
ϕ
" fields on the top of the page display the operating burden specified
on the CT-Object card. The operating burden is the same for all tap or
intertap combinations.
By default, the results are displayed for the nominal burden values.
Use the Results with Op. Burden soft key to display the results for
the operating burden instead. The operating burden is the same for
all tap combinations.
If the results are displayed for the operating burden, the soft key
changes to
Results with Nom. Burden to toggle back to the results
with nominal burden.
See section 6.3.2 below.

key is labeled Pol. in Min. .
Using this soft key you can display the intertap combinations instead
of the tap combinations.

key is labeled Show Taps .
