10.4.4 Phase Information
Under the
Measurement title, there is a drop down list, which allows you to select the
measurement type. This can be Single Phase , Three Phase or Belted Cable (also known
as three core cable with one accessible earth). The Single Phase option should be selected
when each phase is tested separately. For single phase measurements, only channel 1 is
used.
Three Phase should be selected when all three channels are used simultaneously
with separate RFCTs. Belted Cable should be selected when the earth conductor surrounds
all three cores and it is not possible to attach an RFCT to a separate earth conductor for
each core. The drop down list is shown in Figure 27.
Figure 27 - Measurement selection
For
Belted Cable , no phase information is required and so the configure window is not
needed as the phase setting is locked to belted. For Single Phase and Three Phase , once
the option for the measurement type has been selected, the Configure button to the right
must be clicked to set the phase for the measurement.
For single-phase configuration, first, select the phase naming convention from the drop down
list as shown in Figure 28.

This will then populate the drop down list under
Channel 1 , with the selected options. From
this drop down list, then select the appropriate option for the phase being tested and click
OK , as shown in Figure 29.
