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.
