3.2.5.2 VOLTAGE RATIOS
The
screen also enables you to define the voltage ratios. To do this, press the V button to display the following
screen.
The ratios can be programmed to be the same in all channels, or different in one or more of them. The following steps
describe a 3-phase 5-wire hook-up; the available channels are determined by connection type and may be different for
your connection.
1. Highlight Ratio Set-up and press
V1+V2+V3+VN: each channel and the neutral has a different ratio. You are prompted to enter a separate ratio for
each channel (1, 2, and 3) and the neutral (N) as shown in Figure 3-13.
3V + VN: all channels have the same ratio and the neutral has a different ratio. You are prompted to enter a ratio for
the channels and another ratio for the neutral.
4V: all channels have the same ratio. You are prompted to enter the ratio that will apply to all.
4V 1/1: all channels have the same 1/1 ratio.
2. Select the set-up and validate by pressing
3. To select channels, press the ▲ and ▼ buttons to highlight the channel field and press
buttons to navigate within the field, and the ▲ and ▼ buttons to adjust values. When you are finished with the field,
press
to validate (the parameter must be validated to be applied).
4. To return to the Configuration menu, press
For the primary voltage (in kV) and the secondary voltage (in V), it is possible to specify the use of the multiplier 1/√3. If
the phase-to-neutral voltage ratios of phases 1, 2, and 3 are not identical; then all measurements and curves concerning
the phase-to-phase voltages are suppressed.
