Table 8-3: Parameters and settings
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.
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 CT SB2.
Tap in Use The tap combination actually used during operation of the CT (e.g. X1-X4).
Select the tap combination using the soft keys (for example X1-X5, X1-X4). To
select an intertap combination for the tap in use, press the Show Inter Taps soft
key. The MR-Config. card then offers soft keys for the intertap combinations (for
example X2-X4, X3-X4).
After completion of the test, the Test Results card will display the results for the
tap combination selected in this field.
By default, the "Tap in Use" is set to the full tap combination given by the "Number
of Taps".
Taps This column lists all possible tap combinations of the CT (e.g. X1-X5, X1-X4,
X1-X3, ...). The number of available tap combinations depends on the number of
taps specified in the "Number of Taps" field.
When the MR-Config. card is displayed but not in edit mode (i.e., the card’s tab is
highlighted as shown in Figure 8-2 on page 37) you can switch the common tap.
Example:
X1 is assumed as the default common tap, X5 as the highest available tap: Press
the Common Tap to X5 soft key to use X5 as common tap instead of X1. The soft
key then changes to Common Tap to X1.
Using the Show Inter Taps soft key you can display the intertap combinations
instead of the tap combinations. If the intertap combinations are displayed, the soft
key changes to Show Taps.
Examples of intertap combinations: X2-X3, X2-X4, X3-X4.
