Figure 5-18 Information Properties Example for Information Type “Transformer Tap
Changer” (TxTap)
If none of the available encoding formats are selected, each individual tap changer
position may be set in a table. The table is accessed after the pull-down menu 7DEOH
for encoding is opened, by selecting the button to the side.
The encoded transformer tap changer position bit pattern is transformed into digital
values between 1 and 62. An unrecognized pattern is interpreted as position 63.
The number of bits coincides with the number of the binary inputs to be configured,
and limits the number of positions to be represented.
Using the display offset, the beginning of the evaluated bits may have an offset of a
programmed number. The stepping of the transfomer taps may be modified, using the
tap interval feature (see example).
Example
: Four transformer position settings are to be represented by three binary
inputs, using the designators 3 through 6. The encoding is binary.
