Example: If primary value of PT is set as
692.8kV L-L (max value) then primary value
Pressing the “ Up” key will advance to the next
less significant digit. (* Denotes that decimal
point will be flashing).

The “Maximum Power” restriction of 666.6 MVA refers to 120% of nominal current and 120%
of nominal voltage, i.e, 462.96 MVA nominal power per phase.
When the least significant digit had been set, pressing the “ Up” key will advance to the
“Current Transformer Primary Value Confirmation” stage.
The minimum value allowed is 1, the value will be forced to 1 if the display contains zero
