3.2.1.3 Potential Transformer Secondary Value
The value must be set to the nominal full scale secondary voltage which will be obtained from the Transformer
when the potential transformer (PT) primary is supplied with the voltage defined in 3.2.1.2 Potential
Transformer Primary voltage.The ratio of full scale primary to full scale secondary is defined as the
transformer ratio.The PT Secondary value can be set from 100VL-L to 600VL-L (according to input voltage
range).
Pressing the “ ” key accepts the present value and advances to the
“Current Transformer Primary Value” screen (see Section 3.2.1.4).
Similarly, pressing the “ ” key accepts the present value and advances to
the “Potential Transformer Primary Value” screen (see Section 3.2.1.2).
Pressing the “ ” key advances to the “Potential Transformer Secondary
Digit Edit” mode.
Potential Transformer Secondary Digit Edit
Pressing the “ ” or “ ” key scrolls the value of the most significant digit
from 0 through 9 or 9 through 0, respectively.
Pressing the “ ” key accepts the present value at the cursor position and
advances the cursor to the next less significant digit.
After entering the least significant digit, pressing the “ ” key sets the
value and advances to the “Pls Wait” screen followed by the “Potential
Transformer Secondary Value” screen (see Section 3.2.1.3).
NOTE : The default value is 415 VLL.
