Potential Transformer Primary Decimal Point Edit
(Flashing decimal point indicates the cursor position).Initially the “decimal
point must be selected, pressing the “ ” or “ ” key moves the decimal
point position to the
right until it disappears, which means that it has
reached # # # #. after which it returns to #. # # #.
Note: The absence of decimal point in edit mode implies # # # #. decimal
point position.
Pressing the “ ” key accepts the present decimal point position and
advances to the “Potential Transformer Primary Digit Edit” mode.
Note :
PT Values must be set as Line to Line Voltage for Primary as Well as Secondary for all system types
(3P3W/3P4W/1P2W).
NOTE : The default value is ‘0.415 kVLL’.
The PT Primary value can be set from 100 VL- L to 1200 kVL-L. The value will be forced to previously set VL-L
if set less than 100.
Note:
The flashing digit indicates the cursor position, a steady decimal point is present to identify the scaling of
the number until the cursor position coincides with the steady decimal point position. At this stage the digit will
flash.
Potential Transformer Primary Digit Edit
Pressing the “ ” or “ ” key scrolls the value of the most significant digit
from 0 through 9 or 9 through to 0, respectively unless the present
displayed Potential Transformer Primary Value together with the Current
Transformer Primary Value, previously set, results in a maximum system
power of greater than 5400 MVA (1800 MVA per phase) in which case the
digit range gets restricted.
Pressing the “ ” key accepts the present value at the cursor position and
advances the cursor to the next less significant digit.
When the least significant digit has been set, pressing the “ ” key shows “Pls Wait” screen which is followed
by the “Potential Transformer Primary Value” screen (see Section 3.2.1.2).
