Available soft keys

The following soft keys are available if the MR-Config. card is selected but not in edit mode (the card's
tab is highlighted as shown in Figure 9-2):
Table 9-2: Soft keys available in the MR-Config. card
Soft key Description
By default, the table in the MR-Config. card displays the nominal burden values. Use
the Op. Burden soft key to display this table with the operating burden instead.
The soft key then changes to Nom. Burden to switch the table back to the nominal
burden values.
For the nominal burden values the column header is "VA", for the operating burden
values the column header is "Burden".
See "VA" and "Burden" on page 53 for more detailed information.
Using the Common Tap to X# soft key you can select the common tap (e.g. tap X5
instead of default tap X1). The common tap is the tap that is used as reference for all
tap combinations (e.g. X1-X2, X1-X3, X1-X4 etc. if the common tap is X1).
If the highest tap (e.g. X5) is selected as common tap, the soft key changes to
Common Tap to X1.
The default common tap can be selected using the Select Startup Mode option in the
Setting Menu, see chapter 7 on page 32.
Use the Show Inter Taps soft key to display the intertap combinations instead of the
tap combinations. If the intertap combinations are displayed, the soft key is labeled
Show Taps.
Examples of tap combinations: X1-X2, X1-X3, X1-X4, etc.
Examples of intertap combinations: X2-X3, X2-X4, X3-X4, etc.

Parameter Description
Number of Taps Overall number of tap connections available on the multi-ratio CT.
Possible values: Soft keys No. Taps 2, No. Taps 3, No. Taps 4, No. Taps 5 or
No. Taps 6.
If the number of taps selected is 5 or 3, CT Analyzer offers soft keys with
predefined CT ratios when the "I-pn" field is selected in the CT-Object card
(IEEE C57.13 only; see "I-pn" on page 47).
The default number of taps can be selected using the Select Startup Mode option
in the Setting Menu, see chapter 7 on page 32.
When testing a single-ratio CT using the CT SB2 switch box, select No. Taps 2.
However, single-ratio CT testing should preferably be performed using the normal
single-ratio CT test mode of CT Analyzer without using the CT SB2.
