UG-1098 ADE9000 Technical Reference Manual
Rev. 0 | Page 48 of 86
In a Blondel compliant 3-wire delta meter, only the overall
power consumed by the system is meaningful; the individual
phase powers are not meaningful because a line current is
multiplied by a line to line voltage. To obtain the overall power
consumed by the system (active, reactive, and apparent), add
the contribution from Phase A and Phase C.
APPLYING THE ADE9000 TO A NON-BLONDEL
COMPLIANT 4-WIRE WYE SERVICE
To use the ADE9000 in a non-Blondel compliant 4-wire wye
service (such as for ANSI meter forms 6S, 7S, 14S, 29S, 36S, 46S,
and 76S), the Phase A and Phase C voltages are measured and
the Phase B voltage is calculated, VB = −VA − VC. All three
phase currents are measured. For this configuration, write
VCONSEL[2:0] = 010 and connect as shown in Figure 67.

The phasor diagram follows Figure 56. Phase sequence error
detection is performed based on the expected ABC sequence;
see the Phase Sequence Error Detection section for more
information.
To obtain the total power (active, reactive, and apparent), add
the contribution from Phase A, Phase B, and Phase C.
APPLYING THE ADE9000 TO A NON-BLONDEL
COMPLIANT 4-WIRE DELTA SERVICE
To use the ADE9000 in a non-Blondel compliant 4-wire delta
service (such as for ANSI meter forms 8S, 15S, and 24S), the
Phase A and Phase C voltages are measured and the Phase B
voltage is calculated, VB = −VA. All three phase currents are
measured. For this configuration, write VCONSEL[2:0] = 011
and connect as shown in Figure 68.

ADE9000 SERVICE TYPE SUMMARY
To summarize, the ADE9000 can be used in many different
configurations to measure 4-wire wye, 4-wire delta, and 3-wire
delta installations. Table 28 summarizes which VCONSEL[2:0]
and ICONSEL settings to use for each configuration.
