Potential Transformer primary Digit Edit
Pressing the “ Down” key will scroll the value of
the most significant digit from 0 through to 9 unless
the presently displayed Potential Transformer Primary
Value together with the Current Transformer Primary
Value, previously set, would result in a maximum power
of greater than 666.6 MVA per phase in which case
the digit range will be restricted.
Pressing the “ Up” key accepts the present value
at the cursor position and advances the cursor to the
next less significant digit.
The PT Primary value can be set from 100V L-L to 692.8 kV L-L.
Note : the flashing decimal point indicates the cursor position, a steady decimal point will
be present to identify the scaling of the number until the cursor position coincides with the
steady decimal point position. At this stage the decimal point will flash.
When the least significant digit has been set pressing the “ Up” key will advance to the
“Potential Transformer Primary Value Confirmation” stage.
Screen showing display of 0.120 kV i.e. 120 Volts indicating steady decimal point and cursor
flashing at the “hundreds of volts” position.
