Primary Value
Potential Transformer
The nominal full scale voltage which will be displayed as the L1-N, L2-N and L3-N for a
four wire (Ln) system or as L1-2, L2-3 and L3-1 in a three wire(LL) system. This screen
enables the user to display the line to neutral and line to line voltages inclusive of any
transformer ratios, the values displayed represent the voltage in kilovolts (note the x1000
