4.1. Password Protection
Password protection can be enabled to prevent unauthorised access to set-up
screens, by default password protection is not enabled.
Password protection is enabled by selecting a four digit number other than 0000,
setting a password of 0000 disables the password protection.
4. Programming

4.2.1.1 Potential Transformer Primary Value
This screen enables the user to set primary transformer voltage
In terms of kilovolts (note the x1000 enunciator).
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 1000 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.
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 0.239 kV i.e. 239 Volts indicating steady decimal point and cursor
flashing at the “hundreds of volts” position.
Potential Transformer Primary Value Confirmation
This screen will only appear following an edit of the
Potential Transformer Primary Value.
If the scaling is not correct, pressing the “ Down”
key will return to the “Potential Transformer Primary
Value Edit” stage.
Pressing the “ Up” key sets the displayed value
and will advance to the Potential Transformer secondary
Value (See Section 4.2.1.2)

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 4.2.1.1
potential transformer primary voltage. The ratio of full scale primary to full scale secondary is defined
as the transformer ratio.
