1540

In Model 1000 and 1540 combined, the PT Secondary Value is factory set, as marked on the barrel. The PT Secondary Value is user programmable on the 1540 and Integra 1560 two part.

This 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 Section 3.6 Potential Transformer Primary Voltage. This defines the actual full scale voltage that will be obtained from the PT secondary and measured by the unit. The ratio of the full scale primary to full scale secondary voltage is the transformer ratio. Given full scale primary and secondary voltages, the unit knows what primary voltage to display for any given measured secondary voltage.

The secondary voltage displayed is in volts. Following the previous example, on a 2.2 kV system with 110V PT secondary, set this screen to 110.0.

If there is no PT associated with this unit, leave this value unchanged and skip this step.

To accept the displayed PT Secondary Voltage, press >>. The next Set-up screen will appear (Section 3.8 Demand Integration Time).

 

To change the PT Secondary Voltage display, press .

 

Note that the decimal point edit screen will only appear when

 

the display unit is connected to a transducer designed for

 

connection to voltages in the range 57.7 to 139V.

 

Initially all the digits of the present value will be flashing and

 

the decimal point position will be illuminated. This is to indicate

Decimal Point

that initially the ‘multiplier’ must be selected.

 

 

Press to change the decimal point position.

 

Press >> to accept the decimal point position. The Digit Edit

 

screen appears.

 

Set the display to read the value of the PT Secondary voltage,

 

as described in Section 3.2 Number Entry Procedure.

 

After the last digit has been set and accepted, the Confirmation

 

screen will appear.
