10.1.1 Table view modes
When both primary side and non-primary side of transformer windings have tap positions, it is not
easy to show all measurements for all tap combinations in one table. Hence, to show the
measurements easier, there are two table view modes. The first one is the primary table view
mode. In this mode, for each tap position on the non-primary side, there is a measurement table
consisting all primary tap positions. The other view mode is the non-primary table view mode. In
this mode, for each tap position on the primary side, there is a measurement table which includes
all non-primary tap positions.
As an example, assume that there is transformer with 5 taps (1 to 5) on the primary side, and 33
taps (16R to 16L) on the secondary side. Figure 42 shows the primary view mode. In this mode for
each of the secondary taps, there is table with 5 primary taps (33 tables, each 5 taps). The
secondary selected tap is shown on the top and it is possible to change it.

Figure 43 shows on the other hand the secondary view mode. This time for each of the primary
taps, there is table with 33 secondary taps (5 tables, each 33 taps). The primary selected tap is
also shown on the top and it is possible to change it.
