Once the analytic algorithm determines the appropriate phasor for each meter it
will present its findings to the headend. If the reference meter is given a named
phase, then the headend can also determine the names of the phases each meter is
connected to.
If the reference meter is attributed to an offset of 0°, all of the other phasors will be
displaced by 30° relative to the reference value as depicted in Table 5 1.
If, for example, the reference meter is connected AN, then labels can be assigned
to each of the phasors as depicted in Table 5 2.
